greatly increases the risk of accidents and injury.
MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machinery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.
Model G0838 (Mfd. Since 01/20)
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.
-7-
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 reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.
HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material. 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 BEFORE
operating machine.
-8-
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

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 G0838 (Mfd. Since 01/20)
Additional Safety for Wood Lathes
Serious injury or death can occur from getting entangled in, crushed between, or struck
by rotating parts on a lathe! Rotating workpieces can come loose and strike operator or
bystanders with deadly force if they are improperly secured, rotated too fast, or are not strong
enough for the rotational forces required for turning. Improper tool setup or usage can cause
tool kickback or grabbing, resulting in impact injury or entanglement. To reduce the risk of
operator (or bystander) injury or death, anyone operating this machine MUST completely heed
the hazards and warnings below.
VERIFY WORKPIECE INTEGRITY. Verify each
workpiece is free of knots, splits, nails, or foreign
material to ensure it can safely rotate on spindle
without breaking apart or causing tool kickback.
WEAR PROPER PPE. Always wear a face shield
and safety glasses when operating lathe. Do not
wear gloves, necktie or loose clothing. Keep long
hair away from rotating spindle.
PROPERLY
PREPARE
WORKPIECE.
Before mounting, cut off waste portions to
balance workpiece for safe rotation and removal
of large edges that can catch on tooling.
USE CORRECT SPEEDS. Select correct spindle
speed for workpiece size, type, shape, and
condition. Use low speeds when roughing or when
turning large, long, or non-concentric workpieces.
Allow spindle to reach full speed before turning.
SECURE LOCKS. Verify tool rest, headstock,
and tailstock are secure before turning lathe ON.
SECURE WORKPIECE. Use proven setup techniques and always verify workpiece (and centers/
tooling holding workpiece) are well-secured before
starting lathe. Only use high-quality fasteners with
non-tapered heads for faceplate attachment.
ADJUST TOOL SUPPORT. An improperly supported tool may be grabbed or ejected. Adjust tool
rest approximately 1⁄4" away from workpiece and
1
⁄ 8" above workpiece center line to provide proper
support for turning tool. Firmly hold turning tool
with both hands against tool rest.
REMOVE ADJUSTMENT TOOLS. Remove all
chuck keys, wrenches, and adjustment tools
before turning lathe ON. These items can become
deadly projectiles when spindle is started.
CHECK CLEARANCES. Before starting spindle,
verify workpiece has adequate clearance by
hand-rotating it through its entire range of motion.
TEST NEW SETUPS. Test each new setup by
starting spindle rotation at lowest speed and
standing to side of lathe until workpiece reaches
full speed and you can verify safe rotation.
Model G0838 (Mfd. Since 01/20)
AVOID TOOL KICKBACK. This occurs when
turning tool is grabbed or ejected from workpiece
with great force. Commonly caused by poor
workpiece selection/preparation, improper tool
usage, or improper machine setup or tool rest
adjustment.
SAFELY PERFORM ROUGHING. Use correct
tool. Take light cuts, use low speeds, and firmly
support tool with both hands.
USE SHARP TOOLS. Sharp tools cut with
less resistance than dull tools. Using dull tools
increases the risk of tool kickback or grabbing.
SAFELY STOPPING ROTATION. Always allow
rotating workpiece to stop on its own. Never put
hands or another object on workpiece to stop it.
SAFELY MEASURE WORKPIECE. Only measure mounted workpiece after it has completely
stopped. Trying to measure a spinning workpiece
increases entanglement risk.
SANDING/POLISHING. To reduce entanglement
risk, remove tool rest before sanding. Never
completely wrap sandpaper around workpiece.

SECTION 2: POWER SUPPLY
Availability
Circuit Information
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.
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.)
Electrocution, fire, shock,
or equipment damage
may occur if machine is
not properly grounded
and connected to power
supply.
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 240V..... 9.5 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.
Circuit Requirements
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Nominal Voltage.......... 208V, 220V, 230V, 240V
Cycle...........................................................60 Hz
Phase............................................ Single-Phase
Power Supply Circuit.......................... 15 Amps
Plug/Receptacle.............................. NEMA 6-15
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.
-10-
Model G0838 (Mfd. Since 01/20)
Grounding Requirements
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.
This machine is equipped with a power cord that
has an equipment-grounding wire and a grounding
plug. Only insert plug into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.
DO NOT modify the provided plug!

6-15 PLUG
Grounding Pin
Figure 4. Typical 6-15 plug and receptacle.
Serious injury could occur if you connect
machine to power before completing 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).
No adapter should be used with plug. If
plug does not fit available receptacle, or if
machine must be reconnected for use on a
different type of circuit, reconnection must
be performed by an electrician or qualified
service personnel, and it must comply with
all local codes and ordinances.
Model G0838 (Mfd. Since 01/20)
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.

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)
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.
4.
Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.

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.
Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.
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
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.

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.

SECTION 4: OPERATIONS
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, seek additional training from experienced
machine operators, and do additional research
outside of this manual by reading "how-to" books,
trade magazines, or websites.
To reduce your risk of
serious injury, read this
entire manual BEFORE
using machine.
Eye injuries or respiratory problems can
occur while operating this tool. Wear personal protective equipment to reduce your
risk from these hazards.
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
for accidents caused by lack of training.
Model G0838 (Mfd. Since 01/20)
To complete a typical operation, the operator
does the following:
1.
Examines workpiece to make sure it is suitable for turning. No extreme bows, knots, or
cracks should exist.
2.
Prepares and trims up workpiece with a
bandsaw or table saw to make it roughly
concentric.
3.
Installs workpiece between centers, or attaches it to faceplate or chuck.
4.
Adjusts tool rest according to type of
operation, and sets minimum clearance
between workpiece and lip of tool rest to 1⁄4"
gap.
5.
Rotates workpiece by hand to verify spindle
and workpiece rotate freely throughout full
range of motion.
6.
Verifies pulley speed range is set for type of
wood and size of workpiece installed.
7.
Verifies spindle direction switch is in "O" position and spindle speed dial is turned all the
way counterclockwise so spindle does not
start in high speed.
8.
Ties back long hair and clothing and puts on
safety glasses, face shield, and respirator.
9.
Sets spindle direction switch to forward or
reverse, starts spindle, adjusts spindle speed,
and carefully begins turning operation, keeping chisel against tool rest entire time it is
cutting.
10. Turns spindle OFF when cutting operation is

-19-
Workpiece Inspection
Adjusting Headstock
Some workpieces are not safe to turn or may
require modification before they are safe to turn.
Before turning, inspect all workpieces for the
following:
The Model G0838 headstock is equipped with a
cam-action clamping system to secure it to the
lathe bed. When the lever is tightened, a locking
plate lifts up underneath the bed and secures
the headstock in place. The headstock can be
positioned anywhere along the lathe bed.
•
Workpiece Type:
This machine is intended for turning natural
wood products. Never attempt to turn any
composite wood materials, plastics, metal,
stone, or rubber workpieces; turning these
materials can lead to machine damage or
severe injury.
•
Foreign Objects:
Nails, staples, dirt, rocks and other foreign
objects are often embedded in wood. While
cutting, these objects can become dislodged
and hit the operator, cause tool grab, or break
the turning tool, which might then fly apart.
Always visually inspect your workpiece for
these items. If they can't be removed, DO
NOT turn the workpiece.
•
Large/Loose Knots:
Loose knots can become dislodged during
the turning operation. Large knots can cause
a workpiece to completely break in half
during turning and cause machine damage
and injury. Choose workpieces that do not
have large/loose knots.
•
Excessive Warping:
Workpieces with excessive bowing or twisting are unstable and unbalanced. Never turn
these workpieces at high speed, or instability
will be magnified and the workpiece can be
ejected from the lathe causing injury. Only
turn concentric workpieces!
To position headstock along length of bed:
1.
DISCONNECT MACHINE FROM POWER!
2.
Loosen headstock lock lever (see Figure 17).
Headstock Lock
Lever
Figure 17. Location of headstock lock lever.
3.
Slide headstock to desired location on bed,
and use headstock lock lever to secure headstock in position.
Note: The large clamping hex nut underneath
the headstock will require occasional adjusting to ensure proper clamping pressure of
the headstock to the bed. Turn this hex nut
in small increments to fine tune the clamping
pressure as needed.
Always operate lathe with headstock firmly
locked to bed. Otherwise, serious personal
injury may occur, as workpiece or faceplate
could shift during operation or be ejected
from lathe.
-20-
Model G0838 (Mfd. Since 01/20)
Adjusting Tailstock
Adjusting Tool Rest
The tailstock adjusts in the same manner as the
headstock.
The tool rest assembly consists of two components: the tool rest base (or banjo) and the tool
rest. The tool rest base moves forward/backward
and along the length of the lathe bed. The tool
rest rotates and moves up and down in the tool
rest base. Locks for both components allow you to
secure the tool rest in position after making these
adjustments.
To position tailstock along length of bed:
1.
Loosen tailstock lock lever and move tailstock
to desired position along bed, as shown in
Figure 18.
When adjusting the tool rest, position it as close
as possible to the workpiece without actually
touching it. This maximizes support where the
cutting occurs and minimizes leverage, reducing
the risk of injury if a "catch" occurs.
Tailstock Lock
Lever
Figure 18. Tailstock lock lever location.
2.
Re-tighten tailstock lock lever to secure
tailstock to bed.
Note: The large clamping hex nut underneath
the tailstock will require occasional adjusting
to ensure proper clamping pressure of the
tailstock to the bed. Turn this hex nut in small
increments to fine tune the clamping pressure as needed.
Always operate lathe with tailstock firmly
locked to bed. Otherwise, serious personal
injury may occur if tailstock moves/shifts
during operation.
Model G0838 (Mfd. Since 01/20)
Many woodturners typically set the height of the
tool rest 1⁄ 8" above or below the centerline of the
workpiece, depending on their height, the type
of tool they're using, and the type of operation
they're performing.
As a rule of thumb: For most (spindle) turning
operations, the cutting tool should contact the
workpiece slightly above centerline. For most
inside (bowl) turning operations, the cutting tool
should contact the workpiece slightly below
centerline.
Keeping all these factors in mind, your main goal
when adjusting the tool rest should be providing
maximum support for the type of tool being used,
in a position that is safe and comfortable for you.
Improperly supported or positioned cutting
tools can "catch" on workpiece, ejecting
tool from your hands with great force. To
reduce this risk, always ensure tool rest is
properly positioned for each type of operation, cutting tool is firmly supported against
tool rest BEFORE cutting, and cutting tool
is properly positioned to cut at the correct
angle for tool and operation type.
-21-
To adjust tool rest:
1.
Loosen tool rest base lock lever and move
tool rest assembly to desired position on
lathe bed, as shown in Figure 19.
Note: To maximize support, the tool rest
base should always be locked on both sides
of the bed. Never pull the tool rest so far back
that it is only secured on one side.

Indexing
Spindle Turning
Always disconnect lathe from power before
using indexing feature. DO NOT start lathe
with indexing pin inserted into spindle; otherwise entanglement injury and property
damage could occur.
Spindle turning is the operation performed when
a workpiece is mounted between centers in the
headstock and tailstock, as shown in Figure 34.
Bowls, table legs, tool handles, and candlesticks
are typical projects where this operation is used.
Indexing on a lathe is typically used for workpiece
layout and other auxiliary operations that require
equal distances around the workpiece circumference, such as clock faces or inlays.
By inserting the indexing pin into one of the
three outer indexes of the Model G0838 spindle
housing and engaging one of the 12 inner indexes
in the spindle, the workpiece can be positioned in
30° increments, as shown in Figures 32–33.

3.
Using a 1⁄4" drill bit, drill a 1⁄4" deep hole at
center mark on end of the workpiece to be
mounted on headstock spur center.
8.
Install live center into tailstock quill and tighten quill-lock handle to lock quill in position
(refer to Page 23 for additional instructions).
4.
To help embed spur center into workpiece,
cut 1⁄8" deep saw kerfs in headstock end of
workpiece along diagonal lines marked in
Step 1.
9.
Slide tailstock toward workpiece until point of
live center touches workpiece center mark,
then lock tailstock in this position.
5.
If your workpiece is over 2" x 2", cut corners
off workpiece lengthwise to make turning
safer and easier (see Figure 36).

Note: Use tool rest to support opposite end of
workpiece so that workpiece and spur center
do not separate during installation.
10. Loosen quill-lock handle and rotate tailstock
handwheel to push live center into workpiece
at least 1⁄4".
Do not press the workpiece too firmly with
the tailstock or the bearings will bind and
overheat. Do not adjust the tailstock too
loosely or the workpiece will spin off the
lathe. Use good judgment and care, otherwise serious personal injury could result
from the workpiece being ejected at high
speeds.
11. Properly adjust tool rest to workpiece (see
Adjusting Tool Rest on Page 21).
Model G0838 (Mfd. Since 01/20)
Faceplate Turning
12. Before beginning lathe operation, rotate
workpiece by hand to ensure there is safe
clearance on all sides.
Keep lathe tool resting on tool rest the
ENTIRE time it is in contact with workpiece
or when preparing to make contact between
lathe tool and workpiece. Otherwise, spinning workpiece could force lathe tool out
of your hands or entangle your hands with
workpiece. Failure to heed this warning
could result in serious personal injury.
Faceplate turning is when a workpiece is mounted
to the faceplate, which is then mounted to the
headstock spindle, as shown in Figure 38. This
type of turning is usually done with open-faced
workpieces like bowls or plates.
Spindle Turning Tips:
•
When turning the lathe ON, stand away from
the path of the spinning workpiece until the
spindle reaches full speed and you can verify
that the workpiece will not come loose.
•
Use the slowest speed when starting or stopping the lathe.
•
Select the right speed for the size of workpiece
that you are turning (refer to Figure 27 on
Page 25).
•
Keep the turning tool on the tool rest the
ENTIRE time that it is in contact with the
workpiece.
•
Learn the correct techniques for each tool
you will use. If you are unsure about how to
use the lathe tools, read books or magazines
about lathe techniques, and seek training
from experienced and knowledgeable lathe
users.

causing unnecessary vibration and runout. It
is best to mount backing block to faceplate
and turn other surface flat prior to mounting.
Figure 39. Typical attachment of faceplate to
workpiece.
NOTICE
Only use screws with non-tapered heads
(see Figure 40) to attach faceplate to the
workpiece. Screws with tapered heads can
split faceplate or snap off during operation.

backing block.
3.
Drill a 1⁄4" hole through center of backing block.
4.
Look through hole in backing block to line
up center with workpiece, and then glue and
clamp backing block to workpiece.
Note: Allow glue to cure according to manufacturer's instructions.
5.
Follow Steps 1–3 under Mounting
Workpiece on Faceplate (see Page 29) to
attach backing block to faceplate.
Figure 40. Correct and incorrect screw types.
3.
Thread and secure faceplate onto headstock

Model G0838 (Mfd. Since 01/20)
Outboard Turning
Outboard turning is a variation of faceplate
turning and is accomplished with the headstock
positioned so the faceplate is not directly over the
bed, allowing a larger turning capacity than the
swing specification of the lathe.
The only way to rotate the headstock on this
machine is to remove it from the bed first, which
can be a heavy and cumbersome task. A much
simpler alternative to removing the headstock is
to remove the tailstock and slide the headstock
to the other end of the bed. This will position the
spindle so it is not directly over the bed whereby
outboard turning can safely be accomplished.
When outboard turning, ALWAYS use a
floor-mounted tool rest and keep tool in
contact with rest during all turning operations. Failure to do so could cause tool to be
pulled out of operator's control and ejected
at high speed.
Sanding/Finishing
After the turning operations are complete, the
workpiece can be sanded and finished before
removing it from the lathe, as shown in Figure 42.
To outboard turn:
1.
DISCONNECT MACHINE FROM POWER!
2.
Remove tailstock and tool base from machine
by removing hex nuts and clamp washers
located underneath assemblies, then lifting
them from lathe bed.
3.
Loosen headstock, then move it all the way to
tail end of lathe bed, as shown in Figure 41.
Figure 42. Typical sanding operation.
Note: Whenever sanding or finishing, move tool
rest holder out of the way to increase personal
safety and gain adequate working room.

Selecting Turning
Tools
•
Lathe tools come in a variety of shapes and sizes,
and usually fall into five major categories.
•
Scrapers—Typically used where access for
other tools is limited, such as hollowing operations. This is a flat, double-ground tool that
comes in a variety of profiles (round nose,
spear point, square nose, etc.) to match
many different contours.
Gouges—Mainly used for rough cutting,
detail cutting, and cove profiles. The rough
gouge is a hollow, double-ground tool with
a round nose, and the detail gouge is a hollow, double-ground tool with either a round or
pointed nose.
Figure 45. Example of a round nose scraper.
•
Parting Tools—Used for sizing and cutting off work. This is a flat tool with a sharp
pointed nose that may be single- or doubleground.
Figure 43. Example of a gouge.
•
Skew Chisel—A very versatile tool that can
be used for planing, squaring, V-cutting,
beading, and parting off. The skew chisel is
flat, double-ground with one side higher than
the other (usually at an angle of 20°–40°).
Figure 46. Example of a parting tool.
•
Specialty Tools—These are the unique,
special function tools to aid in hollowing, bowl
making, cutting profiles, etc. The Swan Neck
Hollowing Tool shown on Page 33 is a good
example of a speciality tool.

Cleaning &
Protecting
Cleaning the Model G0838 is relatively easy.
Vacuum excess wood chips and sawdust, and
wipe off the remaining dust with a dry cloth. If any
resin has built up, use a resin-dissolving cleaner
to remove it.
Protect the unpainted cast-iron surfaces by wiping them clean after every use—this ensures
moisture from wood dust does not remain on bare
metal surfaces. Keep the surfaces rust-free with
regular applications of products like G96® Gun
Treatment, SLIPIT®, or Boeshield ® T-9.
Lubrication
All bearings for the Model G0838 are lubricated
and sealed at the factory, and do not need additional lubrication.
Wipe a lightly oiled shop rag on the outside of the
headstock spindle. DO NOT allow any oil to get on
the inside mating surfaces of the spindle.
Use the tailstock handwheel to extend the quill
out to the furthest position and apply a thin coat of
white lithium grease to the outside of the quill. DO
NOT allow any oil or grease to get on the inside
mating surfaces of the quill.

Tensioning &
Replacing Belt
4.
Press belt with moderate pressure in center
to check tension. Belt is correctly tensioned
when there is approximately 1⁄8" deflection
when pushed as shown in Figure 51.
— If there is more than 1⁄8" deflection repeat
the tensioning procedure until it is correct.
If tension cannot be achieved replace belt.
The drive belt stretches as the lathe is used.
Most of the stretching will occur during the first
16 hours, but may continue with further use. If the
lathe loses power while making a cut, the belt may
be slipping and need tensioning. If the belt shows
signs of excessive wear, or damage, replace it.
