Revised Steady Rest Instructions
Refer to Page 43 of the Owner's Manual for
a detailed description of the steady rest (see
Figure 1) and its function.
To use steady rest:
1. DISCONNECT LATHE FROM POWER!
2. Loosen clamp knob that secures top half of
steady rest (see Figure 1), and open top.
4. Close steady rest and secure with clamp
knob. If necessary, raise upper finger roller to
allow steady rest to close.
5. Use finger adjustment knobs to adjust all three
finger rollers so they just touch workpiece
without causing deflection.
Note: The finger rollers should properly support the workpiece along the spindle centerline while still allowing it to freely rotate.
Note: You do not need to lubricate the steady rest
finger rollers. They are permanently sealed and
lubricated at the factory.

This lathe is equipped with a foot brake (see
Figure 8) to quickly stop the spindle instead of
allowing the spindle to coast to a stop on its own.
Pushing the foot brake while the spindle is ON
cuts power to the motor and stops the spindle.
After the foot brake is used, the spindle lever must
be returned to the OFF (middle) position to reset
the spindle switches before re-starting spindle
rotation.

Model G0776 (Mfd. Since 7/14)
ELECTRICAL EQUIPMENT INJURY RISKS. You
can be shocked, burned, or killed by touching live
electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.
DISCONNECT POWER FIRST. Always disconnect machine from power supply BEFORE making
adjustments, changing tooling, or servicing machine.
This prevents an injury risk from unintended startup
or contact with live electrical components.
EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.
-11-
WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to avoid
accidental slips, which could cause loss of workpiece control.
HAZARDOUS DUST. Dust created while using
machinery may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material,
and always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hearing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifications—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!
AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.
GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly.
-12-
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.
UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before

CHECK DAMAGED PARTS. Regularly inspect
machine for any condition that may affect safe
operation. Immediately repair or replace damaged
or mis-adjusted parts before operating machine.
MAINTAIN POWER CORDS. When disconnecting cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.
EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intended operation, stop using the machine! Contact our
Technical Support at (570) 546-9663.
Model G0776 (Mfd. Since 7/14)
Additional Safety for Metal Lathes
Serious injury or death can occur from getting entangled in, crushed between, or struck by
rotating parts on a lathe! Unsecured tools or workpieces that fly loose from rotating objects
can also strike nearby operators with deadly force. To minimize the risk of getting hurt or killed,
anyone operating this machine MUST completely heed the hazards and warnings below.
CLOTHING, JEWELRY & LONG HAIR. Tie back
long hair, remove jewelry, and do not wear loose
clothing or gloves. These can easily get caught on
rotating parts and pull you into lathe.
SECURE WORKPIECE. An improperly secured
workpiece can fly off spindle with deadly force.
Make sure workpiece is properly secured before
starting the lathe.
ROTATING PARTS. Always keep hands and body
at a safe distance from rotating parts—especially
those with projecting surfaces. Never hold anything against rotating workpiece, such as emery
cloth, that can pull you into lathe.
CHUCKS. Chucks can be heavy and difficult to
hold. During installation and removal, protect your
hands and precision bed ways by using a chuck
cradle or piece of plywood over the bed ways. Use
lifting equipment, as necessary, for large chucks.
GUARDING. Guards and covers protect against
entanglement or flying objects. Always ensure they
are properly installed while machine is running.
STOPPING SPINDLE. Always allow spindle to
completely stop on its own, or use a brake, if
provided. Never put hands or another object on a
spinning workpiece to make it stop faster.
ADJUSTMENT TOOLS. Remove all chuck keys,
wrenches, and adjustment tools before turning
lathe ON. A tool left on the lathe can become a
deadly projectile when spindle is started.
SAFE CLEARANCES. Before starting spindle,
verify workpiece has adequate clearance by handrotating it through its entire range of motion.
NEW SETUPS. Test each new setup by starting
spindle rotation at the lowest speed and standing
to the side of the lathe until workpiece reaches full
speed and you can verify safe rotation.
SPINDLE SPEEDS. Using spindle speeds that are
too fast for the workpiece or clamping equipment
can cause rotating parts to come loose and strike
nearby people with deadly force. Always use slow
spindle speeds with large or non-concentric workpieces. Never exceed rated RPM of the chuck.
LONG STOCK SAFETY. Long stock can whip
violently if not properly supported. Always support
any stock that extends from the chuck/headstock
more than three times its own diameter.
CLEARING CHIPS. Metal chips can be razor
sharp. Avoid clearing them by hand or with a rag.
Use a brush or vacuum instead.
Model G0776 (Mfd. Since 7/14)
CRASHING. A serious explosion of metal parts
can occur if cutting tool or other lathe component
hits rotating chuck or a projecting part of workpiece. Resulting metal fragments can strike nearby
people and lathe will be seriously damaged. To
reduce risk of crashing, ALWAYS release automatic feeds after use, NEVER leave lathe unattended,
and CHECK all clearances before starting lathe.
COOLANT SAFETY. Coolant can become very
toxic through prolonged use and aging. To minimize toxicity, change coolant regularly. When
using, position nozzle properly to avoid splashing
operator or causing a slipping hazard on floor.
TOOL SELECTION. Cutting with incorrect or dull
tooling increases risk of injury from broken or dislodged components, or as a result of extra force
required for operation. Always use sharp tooling
that is right for the job.
SANDING/POLISHING. To reduce risk of entanglement, never wrap emery cloth around rotating
workpiece. Instead, use emery cloth with the aid
of a tool or backing board.
MEASURING WORKPIECE. To reduce risk of
entanglement, never measure rotating workpieces.
-13-
Additional Chuck Safety
ENTANGLEMENT. Entanglement with a rotating chuck can lead to death, amputation, broken
bones, or other serious injury. Never attempt to
slow or stop the lathe chuck by hand, and always
roll up long sleeves, tie back long hair, and remove
any jewelry or loose apparel BEFORE operating.
CHUCK SPEED RATING. Excessive spindle
speeds greatly increase the risk of the workpiece
or chuck being thrown from the machine with
deadly force. Never use spindle speeds faster than
the chuck RPM rating or the safe limits of your
workpiece.
USING CORRECT EQUIPMENT. Many workpieces can only be safely turned in a lathe if additional
support equipment, such as a tailstock or steady/
follow rest, is used. If the operation is too hazardous to be completed with the lathe or existing
equipment, the operator must have enough experience to know when to use a different machine or
find a safer way.
TRAINED OPERATORS ONLY. Using a chuck
incorrectly can result in workpieces coming loose
at high speeds and striking the operator or bystanders with deadly force. To reduce the risk of this hazard, read and understand this document and seek
additional training from an experienced chuck user
before using a chuck.
-14-
CHUCK CAPACITY. Avoid exceeding the capacity
of the chuck by clamping an oversized workpiece.
If the workpiece is too large to safely clamp with
the chuck, use a faceplate or a larger chuck if possible. Otherwise, the workpiece could be thrown
from the lathe during operation, resulting in serious
impact injury or death.
CLAMPING FORCE. Inadequate clamping force
can lead to the workpiece being thrown from the
chuck and striking the operator or bystanders.
Maximum clamping force is achieved when the
chuck is properly maintained and lubricated, all
jaws are fully engaged with the workpiece, and
the maximum chuck clamping diameter is not
exceeded.
PROPER MAINTENANCE. All chucks must be
properly maintained and lubricated to achieve
maximum clamping force and withstand the rigors
of centrifugal force. To reduce the risk of a thrown
workpiece, follow all maintenance intervals and
instructions in this document.
DISCONNECT POWER. Serious entanglement or
impact injuries could occur if the lathe is started
while you are adjusting, servicing, or installing the
chuck. Always disconnect the lathe from power
before performing these procedures.

SECTION 2: POWER SUPPLY
Availability
Circuit Requirements for 220V
Before installing the machine, consider the availability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrician or
qualified service personnel in accordance with all
applicable codes and standards.
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the power
supply.
Nominal Voltage............................... 220V/240V
Cycle...........................................................60 Hz
Phase.............................................Single Phase
Circuit Rating....................................... 15 Amps
Plug/Receptacle.............................. NEMA 6-15
Cord.........“S”-Type , 3-Wire, 14 AWG, 300VAC
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power supply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)
Full-Load Current Rating
The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.
Full-Load Current Rating at 220V..... 8.5 Amps
The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, consult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid overloading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.

Grounding Instructions
This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
The power cord and plug specified under “Circuit
Requirements for 220V” on the previous page
has an equipment-grounding wire and a grounding prong. The plug must only be inserted into
a matching receptacle (outlet) that is properly
installed and grounded in accordance with all
local codes and ordinances (see figure below).
GROUNDED
6-15 RECEPTACLE
Current Carrying Prongs
6-15 PLUG
Grounding Prong
Figure 9. NEMA 6-15 plug and receptacle.
Serious injury could occur if you connect
the machine to power before completing the
setup process. DO NOT connect to power
until instructed later in this manual.
Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is necessary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service personnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with
a new one.
Extension Cords
We do not recommend using an extension cord
with this machine. If you must use an extension
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:
Minimum Gauge Size............................14 AWG
Maximum Length (Shorter is Better).......50 ft.
No adapter should be used with the plug. If
plug does not fit the available receptacle, or
if machine must be reconnected for use on
a different type of circuit, the reconnection
must be performed by an electrician or
qualified service personnel, and it must
comply with all local codes and ordinances.

Cleanup
The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.
Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.
There are many ways to remove this rust preventative, but the following steps work well in a wide
variety of situations. Always follow the manufacturer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.
Before cleaning, gather the following:
•
Disposable rags
•
Cleaner/degreaser (WD•40 works well)
•
Safety glasses & disposable gloves
•
Plastic paint scraper (optional)
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used to
clean machinery. Avo i d
u sing t h e s e p r o d u c t s
to c l e a n m a c hin e r y.
Many cleaning solvents
are toxic if inhaled. Only
work in a well-ventilated
area.
NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces.
T23692—Orange Power Degreaser
A great product for removing the waxy shipping
grease from your machine during clean up.
Basic steps for removing rust preventative:
1.
Put on safety glasses.
2.
Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it soak
for 5–10 minutes.
3.
Wipe off the surfaces. If your cleaner/degreaser is effective, the rust preventative will wipe
off easily. If you have a plastic paint scraper,
scrape off as much as you can first, then wipe
off the rest with the rag.

Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.
Model G0776 (Mfd. Since 7/14)
Site Considerations
Weight Load
Physical Environment
Refer to the Machine Data Sheet for the weight
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.
The physical environment where the machine is
operated is important for safe operation and longevity of machine components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemicals, airborne abrasives, or extreme conditions.
Extreme conditions for this type of machinery are
generally those where the ambient temperature
range exceeds 41°–104°F; the relative humidity
range exceeds 20%–95% (non-condensing); or
the environment is subject to vibration, shocks,
or bumps.
Space Allocation
Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the maintenance and service described in this manual.
See below for required space allocation.
Electrical Installation
Place this machine near an existing power source.
Make sure all power cords are protected from
traffic, material handling, moisture, chemicals, or
other hazards. Make sure to leave enough space
around machine to disconnect power supply or
apply a lockout/tagout device, if required.
Lighting
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.
Lighting around the machine must be adequate
enough that operations can be performed safely.
Shadows, glare, or strobe effects that may distract
or impede the operator must be eliminated.

Lifting & Placing
HEAVY LIFT!
Straining or crushing injury
may occur from improperly
lifting machine or some of
its parts. To reduce this risk,
get help from other people
and use a forklift (or other
lifting equipment) rated for
weight of this machine.
Do not attempt to lift or move this lathe without
using the proper lifting equipment (such as forklift
or crane) or the necessary assistance from other
people. Each piece of lifting equipment must be
rated for at least 2000 lbs. to support dynamic
loads that may be applied while lifting. Refer to
Needed for Setup on Page 18 for details.
To lift and move lathe:
1. Remove shipping crate top and sides, then
remove small components from shipping pallet.
2. Move lathe to its prepared location while it is
still attached to shipping pallet.
3. Unbolt lathe from shipping pallet.
4. To balance load for lifting, move tailstock and
carriage to extreme right end of bedway, then
lock them in place.
Note: Before attempting to move the carriage, make sure the carriage lock is loose,
the half nut is disengaged, and the power
feed is disengaged (feed selection lever).
5. Remove splash guard so it does not get
damaged when lathe is raised.
-22-
6. Insert round steel bar stock through four lifting holes (see Figure 15).
Note: To properly support the lathe and
avoid damaging lathe components, bar stock
should be at least 1" diameter thick and 49"
long, so it projects 14" from both sides of the
lathe when installed.

7. Attach lifting straps to bar stock and power
lifting equipment (see Figure 15). Make sure
there is enough space between straps and
control rod, feed rod, leadscrew and electrical
cabinet to prevent putting pressure on these
components when lifting.
8. Raise lathe a couple of inches and check balance of load. Have two other people carefully
steady lathe to help prevent it from swinging.
—If load is not safely balanced, immediately lower lathe and resolve issue before
attempting to lift it again.
9. Raise lathe enough to clear shipping pallet
and carefully remove pallet.
10. Lower lathe into position.
11. Re-install splash guard.
Model G0776 (Mfd. Since 7/14)
Anchoring to Floor
Leveling
Number of Mounting Holes............................. 6
Diameter of Mounting Hardware.................. 5 ⁄ 8"
Anchoring machinery to the floor prevents tipping
or shifting and reduces vibration that may occur
during operation, resulting in a machine that runs
slightly quieter and feels more solid.
If the machine will be installed in a commercial or
workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes
may require that it be anchored to the floor.
If not required by any local codes, fastening the
machine to the floor is an optional step. If you
choose not to do this with your machine, we recommend placing it on machine mounts, as these
provide an easy method for leveling and they have
vibration-absorbing pads.
Anchoring to Concrete Floors
Lag shield anchors with lag screws (see below)
are a popular way to anchor machinery to a concrete floor, because the anchors sit flush with the
floor surface, making it easy to unbolt and move
the machine later, if needed. However, anytime
local codes apply, you MUST follow the anchoring
methodology specified by the code.
For accurate turning results and to prevent
warping the cast iron bed and ways, the
lathe bedways MUST be leveled from side
to side and from front to back on both ends.
Recheck the bedways 24 hours after
installation, two weeks after that, and then
annually to make sure they remain level.
Leveling machinery helps precision components,
such as bedways, remain straight and flat during
the lifespan of the machine. Components on a
machine that is not level may slowly twist due to
the dynamic loads placed on the machine during
operation.
If needed, use metal shims between the lathe bed

SECTION 4: OPERATION
Operation Overview
The purpose of this overview is to provide the novice machine operator with a basic understanding
of how the machine is used during operation, so
the machine controls/components discussed later
in this manual are easier to understand.
Due to the generic nature of this overview, it is
not intended to be an instructional guide. To learn
more about specific operations, read this entire
manual and seek additional training from experienced machine operators, and do additional
research outside of this manual by reading "howto" books, trade magazines, or websites.
To reduce your risk of
serious injury, read this
entire manual BEFORE
using machine.
To complete a typical operation, the operator
does the following:
1. Securely mounts workpiece in lathe.
2. Puts on safety glasses and a face shield, rolls
up sleeves, removes jewelry, and secures
any clothing, jewelry, or hair that could get
entangled in moving parts.
3. Installs tooling, aligns it with workpiece, then
backs it away to establish a safe startup
clearance.
4. Removes all setup tools from lathe.
5. Checks for safe clearances by rotating
workpiece by hand at least one full revolution.
6. Moves slides to where they will be used during operation.
7. Sets correct spindle speed for operation.
8. If using power feed, selects proper feed rate
for operation.
To reduce risk of eye or face injury from
flying chips, always wear approved safety
glasses and face shield when operating this
machine.
9. Turns main power switch ON, then resets
EMERGENCY STOP button.
10. Uses spindle lever to start spindle rotation.
11. Uses carriage handwheels or power feed
options to move tooling into workpiece for
operations.
If you are not experienced with this type
of machine, WE STRONGLY RECOMMEND
that you seek additional training outside of
this manual. Read books/magazines or get
formal training before beginning any projects. Regardless of the content in this section, Grizzly Industrial will not be held liable

Chuck & Faceplate
Mounting
Camlock Stud
Installation
This lathe is equipped with a D1-type spindle
nose. This type of spindle uses camlocks that are
adjusted with a chuck key to securely mount a
chuck or faceplate with repeatable precision and
ease.
Follow this procedure to install camlock studs in
chucks, faceplates, or drive plates so they can be
mounted to the spindle.
Note: Skip this section if camlock studs are
already installed.
To install camlock studs:
Never use spindle speeds faster than chuck
RPM rating or safe limits of your workpiece.
Excessive spindle speeds greatly increase
risk of workpiece or chuck being thrown
from machine with deadly force!
1. Lightly oil threads of each stud.
2. Thread studs until datum line is flush with or
just above surface, and alignment groove is
positioned over hole.
This lathe ships with the 3-jaw chuck installed.
This is a scroll-type chuck where all three jaws
move in unison when the chuck key is used.
Alignment
Groove
Cap
Screw
The included 4-jaw chuck features independent
jaws, which are used for square or unevenlyshaped stock, and to mount work that needs to be
adjusted to near zero total indicated runout.
The included faceplate has slots for T-bolts that
hold standard or custom clamping hardware. With
the correct clamping hardware, a faceplate offers
a wide range of uses, including machining nonconcentric workpieces, straight turning between
centers, off-center turning, and boring.
Figure 24. Camlock stud installation.
3. Install a cap screw in hole next to each stud.
These cap screws prevent studs from rotating so they properly engage with camlock
during installation.

and tightening the cap screws.
Model G0776 (Mfd. Since 7/14)
Chuck Safety &
Support Devices
Because chucks are heavy and often awkward
to hold, some kind of lifting, support, or protective device should be used during installation or
removal. The weight and size of the chuck will
determine the appropriate device to use (refer to
the following figure for examples).
Accidentally dropping a chuck can cause
amputation, crushing injuries, or property
damage. To reduce this risk, always use
some kind of lifting, support, or protective
device during installation or removal.
Chuck Installation
To ensure accurate work, it is extremely important
to make sure the spindle nose and chuck mating
surfaces/tapers are clean. Even a small amount of
lint or debris can affect accuracy.
The chuck is properly installed when all camlocks
are tight, the spindle and chuck tapers firmly
lock together, and the back of the chuck is firmly
seated against the face of the spindle all the way
around—without any gaps.
To install chuck:
1.
DISCONNECT LATHE FROM POWER!
2.
Use appropriate lifting, support, or protective device to protect ways and support
chuck during installation process (refer to
Installation & Removal Devices section on
previous page).
3.
Clean and lightly oil camlock studs, then thoroughly clean mating surfaces of spindle and
chuck.
4.
Install chuck by inserting camlock studs
straight into spindle cam holes.

5.
Incrementally tighten camlocks in criss-cross
or star pattern to ensure that chuck seats
evenly against spindle.
6.
When chuck is fully seated and all camlocks
are tight, verify that cam line is between the
two “V” marks on spindle nose, as shown in
following figure.
7.
Verify that chuck fits spindle properly by
checking for any gaps between mating surfaces.
—If there is not a gap, proceed to Step 8.
—If there is a gap, remove chuck, re-clean
mating surfaces carefully, and re-install. If
problem persists, contact our Tech Support.
8.
Verify that chuck/spindle tapers are seated firmly together by removing chuck, per
Chuck Removal instructions, and pay close
attention to how easily tapers release.
—If it was necessary to bump chuck or use
a mallet to release tapers, then they are
seating together properly.
Cam line between “V”s
Figure 27. Cam line positioned between the "V"
marks after the camlocks are fully tightened.
—If cam line is NOT between "V" marks when
camlock is tight, stud may be installed at
incorrect height. To fix this, adjust stud
height as shown in following figure. Make
sure to re-install stud cap screw afterward.
—If adjusting stud height does not correct
problem, try swapping stud positions on
chuck.
—If tapers released easily with little intervention, they are not seated together firmly as
required. Remove chuck, re-clean mating
surfaces carefully, and re-install. If problem
persists, contact our Tech Support.
Registration Marks
Lightly stamp registration marks across the mating
seams of chuck components. These marks will
help you re-install the chuck in the same position
after removal, which ensures consistent chuck
balance and turning results, and allows the
same camlocks and studs to operate together for
consistent locking and unlocking.

Scroll Chuck
Clamping
This 3-jaw, scroll-type chuck has an internal scrollgear that moves all jaws in unison when adjusted
with the chuck key. This chuck holds cylindrical
parts on-center with the axis of spindle rotation
and can be rotated at high speeds if the workpiece
is properly clamped and balanced.
Never mix jaw types or positions to
accommodate an odd-shaped workpiece. The
chuck will spin out of balance and may throw the
workpiece! Instead, use an independent jaw chuck
or a faceplate.

Chuck Jaw Reversal
4-Jaw Chuck
This chuck has 2-piece jaws that consist of
a top jaw and a master jaw. The top jaw can
be removed, rotated 180°, and re-installed in
the reverse position for additional work-holding
options. When reversing the top jaws, always
keep them matched with their original master jaw
to ensure the best fit.
Refer to the Chuck Installation or Chuck
Removal sections for instructions on installing or
removing the 4-jaw chuck.
To reverse 2-piece jaws:
1.
DISCONNECT MACHINE FROM POWER!
2.
Remove cap screws that secure top jaw to
master (bottom) jaw.
3.
Remove top jaw, rotate it 180°, then re-install
it with longest cap screw in tallest portion of
jaw.
4.
Repeat Steps 2–3 with each remaining jaw
(we recommend only reversing one jaw at a
time to keep all original parts together).
The 4-jaw chuck features independently adjustable jaws for holding non-concentric or off-center
workpieces. Each jaw can be independently
removed from the chuck body and reversed for a
wide range of work holding versatility.
Because of dynamic forces involved in
machining a non-concentric or off-center
workpiece, always use a low spindle speed
to reduce risk of workpiece coming loose
and being thrown from lathe, which could
cause death or serious personal injury.
To mount workpiece in 4-jaw chuck:
1. DISCONNECT MACHINE FROM POWER!
Short Cap Screw
Long Cap Screw
Rotate Top

2. Use an appropriate device to protect ways
(refer to Installation & Removal Device
subsection).
3. Use chuck key to open each jaw so workpiece
will fit into spindle opening and lay flat against
chuck face and jaw steps.
4. With help from another person or a holding
device, position workpiece so it is centered in
chuck.
Figure 32. Reversing the chuck jaws.
-34-
Model G0776 (Mfd. Since 7/14)

Faceplate
Refer to the prior Chuck Installation and Chuck
Removal subsections for instructions on installing
or removing the faceplate.
The faceplate included with your lathe can be
used for a wide range of operations, including
machining non-concentric workpieces, straight
turning between centers, off-center turning, and
boring.
The tools needed for mounting a workpiece will
vary depending on the type of setup you have.
Figure 33. 4-jaw chuck tightening sequence.
6.
After workpiece is secured by jaws, use dial
indicator to make sure workpiece is centered
in chuck.
—If workpiece is not correctly centered,
make fine adjustments by slightly loosening one jaw and tightening opposing jaw
until workpiece is correctly positioned (see
below for an example).
Machining non-concentric workpieces at
high speeds could cause workpiece to be
thrown from lathe with deadly force. To
reduce this risk, use a low RPM, and use
counter-weights to balance faceplate or
workpiece.
Failure to properly secure workpiece to
faceplate could cause workpiece to be
thrown from lathe with deadly force. To
reduce this risk, use a minimum of THREE
independent clamping devices to hold
workpiece onto faceplate.

Tailstock
To mount non-concentric workpiece to faceplate:
1.
DISCONNECT MACHINE FROM POWER!
2.
Use appropriate device to protect ways (refer
to Installation & Removal Device subsection).
3.
With help from another person or holding
device to support workpiece, position it onto
faceplate and clamp it in place with a minimum of three independent clamping devices
(see below for an example).
Be sure to take into account rotational and
cutting forces that will be applied to workpiece when clamping it to faceplate. If necessary, use counter-weights to balance assembly and use a dial indicator to make sure
workpiece is properly positioned for your
operation.
Non-Cylindrical
Workpiece
The tailstock is typically used to support long
workpieces at the side opposite the spindle, using
a live or dead center. It can also hold a tapered
drill bit (or a drill chuck with a regular drill bit) for
boring holes. Unlike boring done with a drill press
where the workpiece is fixed and the drill bit
rotates, the drill bit in a tailstock remains stationary while the workpiece is rotated by the spindle.
The entire tailstock can be repositioned and
locked in place along the length of the bed. An
independently controlled offset adjustment allows
the upper part of the tailstock to move perpendicular to the bedways so it can be aligned with
the spindle center (for concentric turning) or offset
from the spindle center (for tapered turning).
The tailstock quill also features independent
adjustment controls that allow it to be advanced
toward the spindle or locked firmly in position.

Note: If the tooling has an open hole in the end,
then a screw can be threaded into the end of the
tool to provide a solid surface for the quill pin to
push against when the quill is retracted for tool
removal. Otherwise, removal of such tooling may
be difficult.
To install tooling in tailstock:
1.
With tailstock locked in place, unlock quill,
then use handwheel to extend it approximately 1".
2.
Thoroughly clean and dry tapered mating
surfaces of quill and center, making sure no
lint or oil remains on tapers.
3.
With a firm and quick motion, insert tool into
quill. Check to see if it is firmly seated by
attempting to twist it—a firmly seated tool will
not twist.
4.
Unlock tailstock and move it until tip of tool
is close to, but not touching, workpiece, then
lock tailstock.

Removing Tooling
1.
Use shop rag to hold tool.
2.
Rotate quill handwheel counterclockwise until
tool is forced out of quill.
—If tool does not come loose by retracting
quill, extend quill and use drift key in slot
shown in the Figure below to remove tool.

Model G0776 (Mfd. Since 7/14)
Offsetting Tailstock
The tailstock quill can be offset from the spindle centerline for turning tapers. Offsetting quill
toward the front of the lathe results in a taper
at the tailstock end. Conversely, offsetting quill
toward the back of the lathe results in a taper at
the spindle end.
Note: The marks on the offset indicator are arbitrary. For a precise offset, use a dial indicator to
check quill movement while adjusting the screws.

Aligning Tailstock to Spindle
Centerline
This is an essential adjustment that should be verified or performed each time the tailstock is used
to turn concentric workpieces between centers
or immediately after offsetting the tailstock when
turning a taper. If the tailstock is not aligned with
the spindle centerline when it is supposed to be,
turning results will be inaccurate along the length
of the workpiece.

Dead Centers
A dead center is a one-piece center that, when
mounted in the tailstock, does not rotate with the
workpiece and is used to support long, slender
workpieces.
Use the dead center in the spindle for operations
where the workpiece rotates with the center and
does not generate friction.
The carbide-tipped dead center can better withstand the effects of friction and is best used in the
tailstock where the workpiece will rotate against
it. The tip of the center must be generously lubricated during the operation to avoid premature
wear and maximize smooth operation. Using low
spindle speeds will also reduce the heat and wear
from friction.

To remove the sleeve and center from the spindle,
insert a piece of round bar stock (or similar)
through the outside end of the spindle. Have
another person hold onto the sleeve and center
with a gloved hand or shop rag, then tap the bar
stock to knock the sleeve loose.
Note: The maximum quill travel is 4", but
we do not recommend extending the quill
more than 2" or stability and accuracy will be
reduced.
Use quill handwheel to feed quill out from
casting approximately 1".
Mounting Center in Tailstock
4.
Insert center into tailstock quill.
Either a carbide-tipped dead center or live center
can be used in the tailstock. Mounting instructions
are the same for both. The Figure below shows
an example photo of a dead center mounted in a
tailstock.
5.
Seat center firmly into quill during workpiece
installation by rotating quill handwheel clockwise to apply pressure with center engaged
in center hole of workpiece.
Carbide-Tipped
Dead Center
Note: Only apply enough pressure with
tailstock quill to securely mount workpiece
between centers. Avoid overtightening center against workpiece, or it may become
difficult to remove later, and it will result in
excessive friction and heat, which may damage workpiece and center.
Removing Center from Tailstock
To remove the center from the quill, hold onto it
with a gloved hand or shop rag, then rotate the
quill handwheel counterclockwise to draw the quill
back into the casting until the center releases.
Figure 48. Example of using a carbide-tipped
dead center installed in the tailstock.
If the center does not come loose by retracting the
quill, extend the quill to expose the slot shown in
the Figure below, then use a drift key to remove
the center.
To avoid premature wear of dead center
or damage to workpiece, use low spindle
speeds and keep tip of dead center mounted
in tailstock well lubricated.

To install tool in tool post:
1.
Position tool in holder so cutting edge extends
just enough to allow tool to cut freely—but no
more. The cutting edge must be well supported to ensure good cutting results and
avoid chipping.
Over-extending a cutting tool from the post
will increase risk of tool chatter, breakage,
or tool loosening during operation, which
could cause metal pieces to be thrown at
the operator or bystanders with great force.
DO NOT extend a cutting tool more than 2.5
times the width of its cross-section (e.g.,
2.5 x 0.5" = 1.25").
2.
Secure tool with at least two set screws.
3.
Adjust cutting tool height to spindle centerline, as instructed in next subsection.
-46-
Figure 58. Cutting tool aligned with spindle
centerline (viewed from tailstock).
There are a number of ways to check and align
the cutting tool to the spindle centerline. If necessary, you can raise the cutting tool by placing
steel shims underneath it. The shims should be
as long and as wide as the cutting tool to properly
support it.
Below are two common methods:
•
Move the tailstock center over the cross slide
and use a fine ruler to measure the distance
from the surface of the cross slide to the tip
of the center. Adjust the cutting tool height so
it is the same distance above the cross slide
as the tailstock center.
•
Align the tip of the cutting tool with a tailstock
center, as instructed in the following procedure. For this to work, the tailstock must
be aligned to the spindle centerline (refer to
Aligning Tailstock To Spindle Centerline
in this manual for detailed instructions).

Spider
Spindle Speed
Your lathe is equipped with a set of outboard
spindle supports otherwise known as a "spider"
(see Figure 61).
Using the correct spindle speed is important for
getting safe and satisfactory results, as well as
maximizing tool life.
To set the spindle speed for your operation, you
will need to: 1) Determine the best spindle speed
for the cutting task, and 2) Configure the lathe
controls to produce the required spindle speed.
Spider Screw
Determining Spindle Speed
Jam Nut
Many variables affect the optimum spindle speed
to use for any given operation, but the two most
important are the recommended cutting speed for
the workpiece material and the diameter of the
workpiece, as noted in the formula shown below.
Spider
Figure 61. Spider assembly located on the outboard spindle.
*Recommended
Cutting Speed (FPM) x 12
Spindle
= Speed
Dia. of Cut (in inches) x 3.14
(RPM)
*Double if using carbide cutting tool
Remove spider screws when not in use.
Always DISCONNECT LATHE FROM POWER
when installing, removing, or adjusting spider screws. Ignoring this warning can lead
to personal injury or machine damage.
The spider is especially designed for supporting
gun barrels during chambering operations; however, it is a great support option for almost any
long workpiece that extends through the outboard
side of the spindle.
The tips of the spider screws have brass wear
pads that hold the workpiece without causing
indents in the finish.
When spider screws are installed, always use the
jam nuts to lock each spider screw in position.
Merely tightening the spider screws against the
workpiece and leaving the jam nuts loose is not
safe. Spiders screws that loosen during operation
can crash into the lathe end cover.
-48-
Figure 62. Spindle speed formula for lathes.
Cutting speed, typically defined in feet per minute
(FPM), is the speed at which the edge of a tool
moves across the material surface.
A recommended cutting speed is an ideal speed
for cutting a type of material in order to produce
the desired finish and optimize tool life.
The books Machinery’s Handbook or Machine
Shop Practice, and some internet sites, provide excellent recommendations for which cutting
speeds to use when calculating the spindle speed.
These sources also provide a wealth of additional
information about the variables that affect cutting
speed and they are a good educational resource.
Also, there are a large number of easy-to-use
spindle speed calculators that can be found on
the internet. These sources will help you take into
account the applicable variables in order to determine the best spindle speed for the operation.

If you have trouble rotating the spindle by hand,
you can use the spindle key or a chuck key to get
additional leverage—be sure to remove the key
when you are done.

Power Feed
Both the carriage and cross slide have power feed
capability when the carriage is engaged with the
feed rod. The rate that these components move
per revolution of the feed rod is controlled by the
quick-change gearbox dial positions and the end
gear configuration.
The feed per revolution and the spindle speed
must be considered together—this is the feed
rate. The sources you use to determine the optimum spindle speed for an operation will also
provide the optimal feed to use with that spindle
speed.
Often, the experienced machinist will use the
feeds and speeds given in their reference charts
or web calculators as a starting point, then make
minor adjustments to the feed rate (and sometimes spindle speed) to achieve the best results.
The carriage can alternately be driven by the
leadscrew for threading operations. However, this
section only covers the use of the power feed
option for the carriage and cross slide components for non-threading operations. To learn how
to power the carriage for threading operations,
refer to Threading on Page 55.
If the feed selection lever and the half nut
are engaged at the same time, machine
damage could occur. Even though there is
a lock-out device to prevent this, it could
break if forced.
To avoid damaging the lathe, ALWAYS make
sure the spindle is completely stopped
BEFORE using the headstock controls to
make changes.
Power Feed Controls
Use Figures 66–67 and the following descriptions to understand the power feed controls.
Note: Before using power feed, you may have to
reconfigure the end gears, depending on how they
are set up. Refer to End Gears on Page 52 for
detailed instructions.

D. Feed Selection Lever: Changes the power
feed to either the cross slide or the carriage.
When the lever is up, the cross slide is selected. When the lever is down, the carriage is
selected. In the middle position neither the
cross slide nor the carriage will move.
Note: The feed selection lever must slide to
the right before it can move downward. This
is a safety feature designed to prevent the
lever from engaging the cross feed when
lifted to disengage the longitudinal feed.
Note: When using this lever, you may need
to slightly rotate the handwheel of the component you are trying to engage, so that the
apron gears can mesh.

Threading
The following subsections will describe how to
use the threading controls and charts to set up the
lathe for a threading operation. If you are unfamiliar with the process of cutting threads on a lathe,
we strongly recommend that you read books,
review industry trade magazines, or get formal
training before attempting any threading projects.

Using the controls on the lathe, follow the example below to understand how to set up the lathe
inch
for the desired threading operation.
—"A2" indicates that the dial marked A–E
must be set to the "A" position, and the dial
marked 1–5 must be set to the "2" position.
To set dials for 32 TPI:
—The sub-row "I" indicates the dial marked
I–II must be set to the "I" position.

Important: Make sure the feed selection lever is
in the disengaged position before attempting to
engage the half nut.
The numbers on the thread dial are used with the
thread dial chart to show when to engage the half
nut during inch threading. Loosen the cap screw
on the thread dial (see Figure 82), pivot the gear
teeth so they mesh with the leadscrew threads,
then re-tighten the cap screw.
Note: The thread dial is not used for metric
threading or pitch turning. You must leave the half
nut engaged from the beginning until the turning
is complete for this type of operation.

When threading, we recommend using slowest speed possible and avoiding deep cuts,
so you are able to disengage half nut when
required and prevent an apron crash!
When the first thread cutting pass is complete,
the operator disengages the carriage from the
leadscrew using the half nut lever. The operator
returns the carriage for the next pass and reengages the half nut using the same thread dial
setting to resume the cut in the previous pass.

Cleaning/Protecting
Because of its importance, we recommend that
the cleaning routine be planned into the workflow
schedule.
Typically, the easiest way to clean swarf from the
machine is to use a wet/dry shop vacuum that is
dedicated for this purpose. The small chips left
over after vacuuming can be wiped up with a
slightly oiled rag. Avoid using compressed air to
blow off chips, as this may drive them deeper into
the moving surfaces or cause sharp chips to fly
into your face or hands.
All unpainted and machined surfaces should be
wiped down daily to keep them rust free and in
top condition. This includes any surface that is
vulnerable to rust if left unprotected (especially
parts that are exposed to water soluble cutting
fluid). Use a quality ISO 68 way oil (see Page 60
for offerings from Grizzly) to prevent corrosion.

The recommended lubrication is based on
light-to-medium usage. Keeping in mind
that lubrication helps to protect the value
and operation of the lathe, these lubrication
tasks may need to be performed more frequently than recommended here, depending on usage.
Failure to follow reasonable lubrication
practices as instructed in this manual could
lead to premature failure of lathe components and will void the warranty.

Place a catch pan under the apron drain plug
shown in Figure 119, then use a 24mm open-end
wrench to remove the fill plug and drain plug, then
empty the reservoir.
Flush the reservoir by pouring a small amount of
clean oil into the fill hole and allowing it to drain
out the bottom. Replace the drain plug, add oil as
previously described, then re-install the fill plug.
This lathe has 15 ball oilers that should be oiled
on a daily basis before beginning operation. Refer
to Figures 120–125 for their locations.
Ball Oilers
Proper lubrication of ball oilers is done with a
pump-type oil can that has a plastic or rubberized cone tip. We do not recommend using metal
needle or lance tips, as they can push the ball too
far into the oiler, break the spring seat, and lodge
the ball in the oil galley.
Lubricate the ball oilers before and after machine
use, and more frequently under heavy use. When
lubricating ball oilers, first clean the outside surface to remove any dust or grime. Push the rubber or plastic tip of the oil can nozzle against the
ball oiler to create a hydraulic seal, then pump the
oil can once or twice. If you see sludge and contaminants coming out of the lubrication area, keep
pumping the oil can until the oil runs clear. When
finished, wipe away any excess oil.

The end gears, shown in Figure 125, should
always have a thin coat of heavy grease to
minimize corrosion, noise, and wear. Wipe away
excess grease that could be thrown onto the
V-belts and reduce optimal power transmission
from the motor.

Handling & Care
Make sure to clean and lubricate any gears you
install or change. Be very careful during handling
and storage—the grease coating on the gears will
easily pickup dirt or debris, which can then spread
to the other gears and increase the rate of wear.
Make sure the end gear cover remains closed
whenever possible to keep the gears free of dust
or debris from the outside environment.
Model G0776 (Mfd. Since 7/14)

Lubricating
1. DISCONNECT LATHE FROM POWER!
2. Open end gear cover and remove all end
gears shown in Figure 125.
3. Clean end gears thoroughly with mineral
spirits to remove the old grease. Use a small
brush if necessary to clean between teeth.
4. Clean shafts, and wipe away any grease
splatters in vicinity and on inside of end gear
cover.
5. Using a clean brush, apply a thin layer of
grease on gears. Make sure to get grease
between gear teeth, but do not fill teeth valleys.
6. Install end gears and mesh them together
with an approximate 0.002"–0.004" backlash.
Once gears are meshed together, apply a
small dab of grease between them where
they mesh together—this grease will be distributed when gears rotate and recoat any
areas scraped off during installation.
7. Close end gear cover before reconnecting
lathe to power.

works well to help clean out the threads. Make
sure to move the carriage out of the way, so you
can clean the entire length of the leadscrew.
Apply a thin coat of oil along the length of the
leadscrew. Use a stiff brush to make sure the oil
is applied evenly and down into the threads.
Note: In some environments, abrasive material
can become caught in the leadscrew lubricant and
drawn into the half nut. In this case, lubricate the
leadscrew with a quality dry lubricant.

Coolant System
Service
The coolant system consists of a fluid tank, pump,
and flexible nozzle. The pump pulls fluid from the
tank and sends it to the nozzle, which controls
the flow of coolant. As the fluid leaves the work
area, it drains back into the tank through the
chip drawer where the swarf and metal chips are
screened out. The chip drawer slides open and is
removable for cleaning.
Use Figures 127–128 to identify the locations of
the coolant system controls and components.
Coolant
Pump
Switch
Nozzle
Figure 127. Coolant controls.
Drain Tube
Chip Drawer
Pump & Tank
(Inside Cabinet)
Although most swarf from machining operations is
screened out of the coolant before it returns to the
tank, small particles will accumulate in the bottom
of the tank in the form of sludge. To prevent this
sludge from being pulled into the pump and damaging it, the pump’s intake is positioned a couple
inches from the bottom of the tank. This works
well when the tank is regularly cleaned; however, if too much sludge is allowed to accumulate
before the tank is cleaned, the pump will inevitably
begin sucking it up.
Hazards
As coolant ages and gets used, dangerous
microbes can proliferate and create a biological
hazard. The risk of exposure to this hazard can
be greatly reduced by replacing the old fluid on a
monthly basis, or as indicated by the fluid manufacturer.
The important thing to keep in mind when working with the coolant is to minimize exposure to
your skin, eyes, and lungs by wearing the proper
PPE (Personal Protective Equipment), such as
long-sleeve waterproof gloves, protective clothing,
splash-resistant safety goggles, and a NIOSHapproved respirator.
BIOLOGICAL & POISON
HAZARD!
Use the correct personal protection equipment
when handling coolant.
Follow federal, state,
and fluid manufacturer
requirements for proper
disposal.
Figure 128. Additional coolant components.
The chip drawer is very heavy. Unless
removing the chip drawer for cleaning, do
not pull it out more than halfway to prevent
it falling and causing impact injuries. If
removing the drawer for cleaning, get
assistance!

Machine Storage
To prevent the development of rust and corrosion,
the lathe must be properly prepared if it will be
stored for a long period of time. Doing this will
ensure the lathe remains in good condition for
later use.
7. Place a few moisture absorbing desiccant
packs inside of the electrical box.
8. Cover the lathe and place it in a dry area that
is out of direct sunlight and away from hazardous fumes, paint, solvents, or gas. Fumes
and sunlight can bleach or discolor paint.
1. Run the lathe and bring all reservoirs to operating temperature, then drain and refill them
with clean oil.
9. Every few months, rotate by hand all geardriven components a few times in several
gear selections. This will keep the bearings,
bushings, gears, and shafts well lubricated
and protected from corrosion—especially
during the winter months.
2. Pump out the old coolant, then add a few
drops of way oil and blow out the lines with
compressed air.
10. Slide the carriage, tailstock, and steady rest
down the lathe bed to make sure that way
spotting is not beginning to occur.
3. DISCONNECT LATHE FROM POWER!
Bringing Lathe Out of Storage
Preparing Lathe for Storage
4. Thoroughly clean all unpainted, bare metal
surfaces, then apply a liberal coat of way oil,
heavy grease, or rust preventative. Take care
to ensure these surfaces are completely covered but that the rust preventative or grease
is kept off of painted surfaces.
5. Lubricate the machine as outlined in the
lubrication section. Be sure to use an oil can
to purge all ball oilers and oil passages with
fresh oil.
1. Re-install the V-belts and re-tension them
(refer to Page 83) if you removed them for
storage purposes.
2. Remove the moisture-absorbing desiccant
packs from the electrical box.
3. Repeat the Test Run and Spindle Break-In
procedures, beginning on Page 28.
4. Add coolant, as described in Coolant System

Adjusting Backlash
3. Tighten backlash adjustment set screws
shown in Figure 130 in small increments.
Backlash is the amount of play in a leadscrew
and can be felt as the free play in a handwheel
when changing direction of rotation. The amount
of the backlash can be viewed on the handwheel
micrometer-collar graduated dial.
When adjusting backlash, tighten the components
enough to remove backlash, but not so much that
the components bind the leadscrew, making it
hard to turn. Overtightening will cause excessive
wear to the sliding block and leadscrew.

Adjusting Gib
The goal of adjusting the gib screws is to remove
sloppiness or "play" from the ways without overadjusting them to the point where they become
stiff and difficult to move.
In general, loose gibs cause poor finishes and
tool chatter; however, over-tightened gibs cause
premature wear and make it difficult to turn the
handwheels.
The cross-slide and compound slide on this lathe
each use a long steel wedge called a gib that is
positioned between the component and its dovetailed-ways. Gib screws at each end move the gib.
Depending upon which direction the gib moves,
the space between the sliding ways increases or
decreases to control the rigidity of the cross slide
and compound slide.
Cross Slide Gib
Make sure the ways and leadscrew have been
cleaned and re-lubricated before beginning any
adjustments. Refer to Ball Oiler Lubrication on
Page 68 for instructions and lubricant specifications.

Before adjusting the gibs, loosen the locks for the
devices so the gibs can slide freely during adjustment, then lubricate the ways.
The gib adjustment process usually requires
some trial-and-error. Repeat the process as necessary until you find the best balance between
loose and stiff movement. Most machinists find
that the ideal gib adjustment is one where a small
amount of drag or resistance is present, yet the
handwheels are still easy to move.

Compound Slide Gib
Figure 132 shows the gib arrangement for the
compound slide. The compound slide gib adjusts
in the same manner and with the same tools
as the cross slide gib. However, in this case, to
increase or decrease tension, the gib adjustment
screw directions are reversed.
The saddle gib is located on the bottom of the
back edge of the slide (Figure 134). This gib is
designed differently than the cross or compound
slide gibs. Instead of being a wedge-shaped plate,
it is a flat bar. The gib pressure is applied by four
set screws. Hex nuts secure these set screws in
place, so they will not loosen during operation.

Saddle Gib
The saddle is supplied with a carriage lock on
the front right-hand side of the slide (see Figure

rigidity when making face cuts. Before making
adjustments to the saddle gib, make sure that this
lock is loose by turning it counterclockwise one
full turn.
IMPORTANT: Do not loosen the carriage lock
more than a couple of turns or the components
inside will come apart. Re-installing these components is difficult and time consuming.

Adjusting Half Nut
Replacing Shear Pin
The half-nut mechanism can be adjusted if it
becomes loose from wear. The half nut is mounted in ways with a gib exerting pressure between
components to reduce sloppy movement. The
half-nut gib is a flat bar-type gib, similar to the saddle gib, and is tensioned with three set screws.
A straight 4 x 25mm brass shear pin (Figure 136)
holds the leadscrew and the drive hub together.
The pin is designed to break and disengage the
power transfer to the leadscrew to help protect
more expensive lathe components in the case of
a carriage crash or the lathe is overloaded.

—If one half of the shear pin has fallen out
and the leadscrew shaft can be seen
through the pin hole, rotate the leadscrew
until the end of the inner sheared pin can
be seen. Next, insert the 3 ⁄ 16" dowel punch
into the hole and tap the pin out through
the other side.
—If the shear pin halves are still stuck in both
sides of the drive hub, center punch one
of the pins and drill an 1⁄8" hole in the pin
approximately 1⁄4" deep. Next, thread the
#8 wood screw into the hole until the screw
begins to thread into the brass. Using pliers, pull the pin from the hole, and drive the
rest of the pin out as outlined above.
4. Align holes in drive hub with hole in leadscrew,
and tap new shear pin into position until it is
flush.
Tip: For easy shear pin replacement in the
future, use the center punch or a scribe and
mark the end of the drive hub and the side of
the leadscrew with a timing mark to indicate
where true hole alignment is located. Next,
scribe a line on the leadscrew just where it
enters the drive hub, this line will indicate correct depth of leadscrew. Should the pin ever
shear again, line-up the marks, and drive out
the pin pieces, and tap in the new pin.
Adjusting Feed
Clutch
This lathe is equipped with a feed rod clutch,
shown in Figure 137, that connects the feed drive
hub with the feed rod through a set of spring-loaded internal steel balls. This clutch helps protect
the apron feed system from overload. The feed
rod clutch comes set from the factory, and unless
there is a problem, it needs no adjustment.
Feed Clutch
Set Screws
Feed Rod
Figure 137. Feed rod clutch.
The clutch may slip if the path for the carriage
or the cross feed is obstructed during turning
or facing operations, the tool bit crashes into
a workpiece shoulder, the carriage lock is left
applied when the feed selection lever is engaged,
or if too deep of a cut is taken, causing a sudden
binding of the tool and workpiece.
It is imperative to recognize however, the clutch
is not a foolproof way of protecting your lathe
from damage if an operational mistake is made, a
chuck-carriage crash occurs, or general machine
overloading occur on a regular basis.
Never completely tighten the feed clutch set
screws past the normal setting outlined in this
procedure in an attempt to completely eliminate
clutch slip. Doing so will void the warranty, and
can lead to a non-slipping clutch, resulting in catastrophic gearbox damage.

Tool Needed
Qty
Hex Wrench 4mm............................................... 1
To adjust feed rod clutch:
1. DISCONNECT LATHE FROM POWER!
2. Engage apron longitudinal feed selection
lever and gearbox and headstock levers so
feed rod does not move.
—If the clutch slips during normal work loads
and no problem exists with the feed system, the clutch spring pressure must be
increased. Using the 4mm hex wrench,
tighten the (4) set screws 1⁄8-turn and
recheck for slippage.
—If for any reason the clutch is bound
up or locked, and does not slip when it
should, the clutch spring pressure must be
reduced. Using the 4mm hex wrench, loosen the (4) set screws 1⁄8-turn, and recheck
for slippage.
Adjusting Tailstock
Lock
When pushed toward the spindle, the tailstock lock
holds the tailstock firmly in place on the bedway
with a locking plate underneath. If the position of
the lock lever is difficult to use, the lever can be
adjusted for the best leverage.

Tensioning/
Replacing V-Belts
3. Adjust hex nuts on motor mount bolts (see
Figure 141) until there is approximately 3⁄4"
deflection in each V-belt when it is pushed
with moderate pressure.
V-belts stretch and wear with use, so check the
tension after the first three months and then every
six months to ensure optimal power transmission.
Replace all of the V-belts as a matched set if any
of them show signs of glazing, fraying, or cracking.

Adjusting Spindle
Bearing Preload
This lathe is shipped from the factory with the
spindle bearing preload set. If the spindle ever
develops end-play and the workpiece finish suffers, you can re-establish the bearing preload,
remove the end-play, and correct the workpiece
finish issue.
Tools Needed
Qty
Hook-Style Spanner Wrench 68-75mm.............. 1
Dial Indicator with Magnetic Base...................... 1
Heavy Dead Blow Hammer................................ 1

5. Loosen inner spanner nut one turn.
1. Run lathe for 20 minutes on high speed to
bring lathe to normal operating temperature.
Note: You may have to tap on the outboard
end of the spindle as explained in Step 6, to
help unload the spindle and break the spanner nut loose.
2. DISCONNECT LATHE FROM POWER!
3. Remove chuck and spider bolts, then shift
spindle to neutral and remove headstock
gear cover to access outboard end of spindle
(see Figure 142).

NOTICE
For the next step, DO NOT strike the wooden block with excessive force. If you do,
you can cause the tapered roller bearings
to indent the mating races. If this damage occurs, one or more spindle bearings
will have to be replaced, as this damage
will generate vibration at higher spindle
speeds.
Figure 142. Location of outboard end of spindle.
-84-
Model G0776 (Mfd. Since 7/14)
6. Place wood block over outboard end of
spindle. Tap it a few times with dead blow
hammer (see Figure 144). Your goal is to
slide spindle forward just enough to introduce
spindle end-play that you can feel by hand.
9. Insert chuck wrench into a cam socket to prevent spindle from turning, then tighten inner
spanner nut until dial indicator needle just
stops moving (see Figure 146).
Note: For convenience and accuracy, we
recommend having another person watch the
dial while you tighten the inner spanner nut.
Figure 144. Unseating spindle bearings to introduce spindle end-play.
Figure 146. Adjusting spindle bearings.
7. Place dial indicator on cross slide and move
carriage toward headstock until contact point
of indicator touches spindle face (see Figure
145).
While tightening spanner nuts, rock spindle
back and forth slightly with cam key to make
sure spindle tapered roller bearings seat
properly in their races.
When dial indicator needle stops moving,
there will be zero spindle end-play and no
bearing preload. It is essential that you find
this point without tightening spanner nut
too much and inadvertently pre-load spindle
bearings.
If you think you have gone past zero end-play
point, unload bearings by repeating Steps
5–6, then re-tighten inner spanner nut until it
has reached zero end play position.
10. Tighten spanner nut an additional 1⁄16-turn.
Figure 145. Dial indicator setup.
8. Move carriage an additional 0.100" toward
headstock, and zero dial indicator.
11. Without allowing inner spanner nut to tighten
any farther, tighten outer spanner nut against
inner nut.
Do not overtighten outer spanner nut because
additional preload can force bearings even
tighter against races in headstock and cause
headstock to compress or crack, or bearing
may quickly fail.
12. Re-install outboard gear cover.
Model G0776 (Mfd. Since 7/14)

Confirming Bearing Preload
1. Re-attach all removed lathe components and
prepare it for operation.
Removing/Installing
Gap Insert
2. Install chuck and tighten jaws.
3. Set spindle speed to its highest setting.
4. Connect lathe to power and turn lathe spindle
ON.
5. Periodically shutting down lathe a few times
and checking temperature, let lathe run for 20
minutes.
6. Turn spindle OFF, disconnect lathe from
power, and check temperature of spindle.
—If the spindle nose is slightly warm to the
touch, you have correct bearing preload.
—If the spindle nose is hotter than you
can comfortably keep your hand on, the
preload is too tight and you must repeat
the bearing preload adjustment procedure.
When repeating the procedure, rotate the
inner spanner nut a little less during Step
10 in the preceding instructions.
This lathe is equipped with a removable gap
insert that will allow for turning large diameter
workpieces. The gap was seated, pre-loaded,
and then ground for precise mating and alignment
at the factory. Removing the gap can cause the
lathe insert to slightly spring out of shape. When
re-installed, there is no guarantee that original
alignment and flush mating will be the same. For
this reason, removing the gap is considered a
permanent alteration to the lathe, even if it is later
re-installed.

5. Tap outside of gap piece with a dead blow
hammer to loosen it, and, with the help of
another person, remove gap piece.
Checking/Replacing
Brake Shoes
Re-installing Gap
1. Clean all mating surfaces completely with
mineral spirits and inspect and remove any
burrs. ALL MATING SURFACES MUST BE
ABSOLUTELY CLEAN!
2. Lightly oil a lint-free cloth with way oil, and
rub a thin film into pores of freshly cleaned
gap surfaces. Next, place gap in position on
lathe bed.
3. Back off threaded dowel pin jam nuts until
they are flush with end of pins, then drop pins
into pin holes in gap.
4. Jostle gap closer to its final alignment until
pins seat naturally.
5. Install and lightly snug four cap screws in an
order that will draw gap closer into alignment.
Using blocks of wood and clamps to get mating surfaces into alignment can also be helpful.
6. When alignment and flush mating is acceptable, tighten four cap screws in a pattern that
will maintain or improve the alignment.
7. Wait 24 hours, and check for quality of mating. If unacceptable, use clamps and blocks
of wood, and loosen and tighten appropriate
cap screws to draw-in and release certain
areas of gap to achieve the required alignment.
If the brake responds poorly, verify that the all linkage is tight and that the belts are tight and free of
oil or grease. Replace the brake shoe set if the
lining thickness is 3 ⁄ 16" or less. When inspecting
for amount of brake wear measure from the following locations:
•
If riveted linings are used, the measurement is
taken from the rivet heads to the lining surface
as viewed from the brake pad surface.
•
If bonded linings are used, the measurement
is taken from the metal shoe surface to the
surface of the lining as viewed from the side
of the brake shoe.
When inspecting the drum, if the drum pulley is
bell-mouthed, cracked, or shows deep groves,
replace it. For minor scoring, the drum pulley can
be dressed with sandpaper or turned on a lathe.

2. Remove headstock gear cover.
8. When satisfied with alignment, tap dowel pins
the rest of the way into the gap until they are
in a fully seated position, and thread jack nuts
down until they just contact the gap.
9. Tighten preload cap screw inward until it contacts headstock and resistance can be felt,
then tighten it an additional 3⁄4-turn.
