FOR YOUR OWN SAFETY, READ THE MANUAL BEFORE
OPERATING THE TOOL. Learn the machine’s application
and limitations, plus the specific hazards particular to it.
ALWAYS USE A FULL FACE SHIELD-Strongly
recommended (must comply with ANSI STANDARD
Z87.1 -USA) Everyday eyeglasses usually are only
impact-resistant, and safety glasses only protect eyes. A
full face shield will protect the eyes and face. Also, use
face or dust mask if cutting operation is dusty.
WEAR PROPER APPAREL. Do not wear loose clothing,
gloves, neckties, rings, bracelets or other jewelry which
may get caught in moving parts. Non-slip footwear is
recommended. Wear protective hair covering to
contain long hair.
USE EAR PROTECTORS. Use ear muffs for extended
period of operation. Use muffs rated to 103 DBA LEQ (8
hour).
DON’T USE IN DANGEROUS ENVIRONMENT. Don’t use
power tools in damp or wet locations, or expose them
to rain. Keep work area well lighted. The DVR Galaxi
Lathe is intended for indoor use only. Failure to do so
may void the warranty.
KEEP WORK AREA CLEAN. Cluttered areas and benches
invite accidents. Build-up of sawdust is a fire hazard.
KEEP CHILDREN AND VISITORS AWAY. The Nova DVR
Galaxi is not recommended for children and infirm
persons. Such personnel and onlookers should be kept
a safe distance from work area.
MAKE WORKSHOP CHILDPROOF with locks, master
switches, or by removing starter keys.
GROUND ALL TOOLS. If the tool is equipped with a
three-prong plug, it should be plugged into a three-hole
electrical receptacle. If an adapter is used to
accommodate a two-prong receptacle, the adapter plug
must be attached to a known ground. Never remove
the third prong.
MAKE SURE TOOL IS DISCONNECTED FROM POWER
SUPPLY while the motor is being mounted, connected,
or reconnected.
DISCONNECT TOOLS FROM WALL SOCKET before
servicing and when changing accessories such as blades,
bits, cutters and fuses etc.
AVOID ACCIDENTAL STARTING. Make sure switch is in
the “Off” position before plugging in power cord.
NEVER LEAVE MACHINE RUNNING UNATTENDED. Do
not leave machine unless it is turned off and has come
to a complete stop.

accessories may cause hazards.
DON’T FORCE THE TOOL. It will do the job better and be
safer at the rate for which it was designed.
MAINTAIN TOOLS IN TOP CONDITION. Keep tools sharp
and clean for best and safest performance. Follow
instructions for lubricating and changing accessories.
NEVER STAND ON TOOL. Serious injury could occur if the
tool is tipped or if the cutting tool is accidentally
contacted.
REMOVE ADJUSTING KEYS AND WRENCHES. Form a habit
of checking to see that keys and adjusting wrenches are
removed from tool before turning it on.
DON’T OVERREACH. Keep proper footing and balance at
all times.
DIRECTION OF FEED. Feed work into a blade or cutter
against the direction of rotation of the blade or cutter
only.
PAY ATTENTION TO WORK. Concentrate on your work. If
you become tired or frustrated, leave it for a while and
rest.
SECURE WORK. Use clamps or a vice to hold work when
practical. It’s safer than using your hand and frees both
hands to operate tool.
CHECK DAMAGED PARTS. Before further use of the tool,
any part that is damaged should be carefully checked to
ensure that it will operate properly and perform its
intended function. Check for alignment of moving parts,
binding of moving parts, mounting, and any other
conditions that may affect its operation. Any damaged
part should be properly repaired or replaced.
DRUGS, ALCOHOL, MEDICATION. Do not operate machine
while under the influence of drugs, alcohol, or any
medication.
DUST WARNING. The dust generated by certain woods
and wood products can be harmful to your health. Always
operate machinery in well-ventilated areas and provide

ADDITIONAL SAFETY RULES FOR WOOD LATHES
WARNING! Failure to follow these rules may result in serious personal injury.
1.
SEEK INSTRUCTION. If you are not thoroughly familiar with
the operation of wood lathes, obtain advice from your
supervisor, instructor, or other qualified person. Instruction
from a qualified person is strongly recommended.
2.
DO NOT OPERATE LATHE until it is completely assembled
and installed. Follow instructions and recommendations.
3.
FOLLOW ELECTRICAL CODES. Make sure wiring codes and
recommended electrical connections are followed and that
the machine is properly grounded.
4.
WHEN REPLACING THE FUSE (on relevant models),
completely isolate power when removing the fuse. It is
imperative the plug is removed from the mains supply
before the fuse is removed. Replace fuse cap before
reconnecting to mains.
5.
6.
DO NOT OPEN THE SWITCH AND REAR COVERS.
Components can carry dangerous voltages even when
isolated from mains power.
ALWAYS ENSURE SPINDLE FIXTURES (E.G. FACEPLATES
ETC.) ARE LOCKED TO SPINDLE in case spindle reverse is
engaged. Otherwise they will unwind from spindle. See
"Mounting a Faceplate to a chuck" section.
7.
WHEN SPINDLE REVERSE IS ENGAGED DO NOT USE
CHISELS OR CUTTING TOOLS - USE FOR SANDING ONLY
8.
KEEP WORK AREA CLEAN. Do not turn the lathe on before
clearing the lathe of all objects (tools, scraps of wood, etc.).
Keep the nearby area and floor clear of debris.
9.
CHECK SET-UP with spindle off. Examine the set-up
carefully and rotate the work piece by hand to check
clearance and check speed is correctly selected before
turning on spindle.
10.
DO NOT MAKE ADJUSTMENTS when the lathe or work
piece is turning. Make all adjustments with power OFF.
11.
TIGHTEN ALL CLAMP HANDLES on the headstock, tailstock,
and toolrest before operating lathe.
12.
EXAMINE WORK PIECE and glue joints before turning to
make sure it has no defects that would cause it to break
when turning.
13.
ALWAYS CHECK CORRECT SPEED IS SELECTED BEFORE
SWITCHING ON SPINDLE.
14.
USE LOWEST SPEED when turning a new or unbalanced
work piece.
15.
TURN AT RECOMMENDED SPEED. Always operate the
lathe at the recommended speeds. Consult this manual for
suggested speeds.
16.
ADJUST TOOLREST close to the work piece. Before turning,
revolve the stock by hand to make sure it clears the rest. At
intervals, stop the lathe and readjust the Toolrest.
17.
KEEP TOOL ON TOOLREST. The lathe tool or chisel should be
on the Toolrest before the lathe is turned ON. Tools should
remain on the Toolrest whenever the tool is engaged in
contact with the work piece.
18.
REMOVE TOOLREST when sanding or polishing so fingers do
not get pinched.
19.
USE CORRECT LATHE TOOLS. Do not use spindle turning chisels
for faceplate mounted work, and vice versa. Spindle turning
tools used for faceplate mounted work may grab the work piece
and pull the chisel from your control.
20.
WHEN ROUGHING STOCK do not jam the lathe tool or chisel
into work piece or take too big a cut.
21.
DO NOT POUND WORK PIECE into headstock drive (spur) center
when turning between centers. Pound the drive center into the
work piece with a soft mallet before installing it between
centers in the lathe.
22.
DO NOT USE TAILSTOCK to drive work piece into the drive (spur)
center when turning between centers. Secure work between
centers with light pressure from the tailstock quill action.
23.
FASTEN STOCK SECURELY BETWEEN CENTERS. Make sure the
tailstock is locked before turning on the power.
24.
NEVER LOOSEN TAILSTOCK Quill or Tailstock while work piece is
turning.
25.
CORRECT USE OF FACEPLATE. When faceplate turning, make
sure work piece is securely fastened to the faceplate and that
appropriate size faceplate is used to support the work piece. Any
screw fasteners must not interfere with the turning tool at the
finished dimension of the work piece. Rough-cut the work piece
as close as possible to finished shape before installing on
faceplate.
26.
DO NOT OPERATE LATHE IF DAMAGED OR FAULTY. If any part
of your lathe is missing, damaged or broken, in any way, or any
electrical component fails, shut off the lathe and disconnect the
lathe from the power supply. Replace missing, damaged, or
failed parts before resuming operation.
27.

Mounting a Faceplate or a Chuck
1.
Use the Spindle Index Pin to lock the headstock spindle.
IMPORTANT NOTE: The Index Pin is designed for indexing purposes only, not for leveraging against when removing
faceplates, inserts and chucks. For this we recommend holding the spindle using the operating bar through the 2 LHB holes
(Lathe Hand Brake).
2.
Remove the side-locking screw, then wind the faceplate or
chuck onto the spindle threads. A spindle washer in
between may be used to make removal easier.
Faceplate
Spindle
WARNING!
The faceplate or chuck body must contact the shoulder on the
spindle bearing.
122-0217-015
13
3.
4.
A groove is provided on the spindle for a special locking grub screw that is used in conjunction with Nova chucks and
accessories to prevent unwinding during reverse operations. Insert the side-locking grub screw and tighten firmly in place,
without over tightening.
Pull and turn the Spindle Index Locking Knob and place it in the "Unlock" position.
WARNING!
It is important that all Chucks and Faceplates that are used on the DVR spindles have a side-locking function. Some older
NOVA/Teknatool products may not have a side-locking function. If any of these products are intended to be used on the DVR
spindle they will need to undergo a modification to include the side-locking function or new products purchased with a sidelocking function. All spindle mounted products produced by Teknatool International for the DVR Lathe have side-locking
functions*. The side-locking function should be used at all times while running the chuck on the spindle during operation.
Without this function engaged the Chuck or Faceplate may unwind from the spindle during operation.
WARNING!
When installing or removing the Faceplate or Chuck from the spindle, the side-locking grub screw MUST be completely
removed. This avoids any potential damage to the spindle that the grub screw may cause if is not completely removed when
winding the Faceplate or Chuck on or off the spindle.
*Exception 1. When an ILNS insert is used with a FP150Z faceplate on the DVR 2024 or a Spindle adaptor, the insert or adaptor
must be locked onto the faceplate to avoid it unwinding when the spindle is run in reverse. Loctite 272 Threadlocker is
recommended.
*Exception 2. Customers with dedicated threaded Teknatool chucks who intend using the chuck on the NOVA GALAXI DVR 1644
Spindle must have a side-locking function adapted to the chuck before running it. Chucks with M33 threads may apply for
Europe.

To adjust the Toolrest, loosen the Toolrest Clamp Handle,
position the Toolrest, and tighten the clamp handle.
Adjust the Toolrest close to the work piece. Exact positioning
may be varied to suit the turner. Revolve the stock by hand to
make sure it clears the rest before starting the lathe.
At intervals, stop the lathe and readjust the Toolrest.
WARNING!
Lathe tools and chisels should remain on the Toolrest whenever
the tool is in contact with the work piece. Remove the Toolrest
when sanding or polishing so fingers do not get pinched.
Tailstock
To open the tailstock door, loosen the thumb screw until it is released from the threaded hole in the tailstock body.
To move the Tailstock along the bed, release the Cam Lock Lever,
slide the Tailstock to the desired position, and tighten the Lever to
lock into place.
Quill Eject Direction
WARNING!
Never loosen the Tailstock Quill or Tailstock while the work piece is
turning.
To move the Tailstock quill in or out, loosen the Quill Lock and turn
the Handwheel. Lock the quill in place with the Quill Lock.
The Tailstock Quill accepts centers and accessories with no. 2 Morse
taper (#2 MT). To install a taper use a quick, firm action by hand. Do
not pound the taper into the hole.
To remove a taper, either wind the quill into the tailstock until the
taper is ejected or insert the operating bar through the Tailstock
Quill hole. While holding the taper so it doesn’t fall, tap it out.
The Tailstock Quill is hollow, allowing you to bore holes through
turnings if a hollow center is used.

TURNING TIPS
The DVR Motor technology is not just a variable speed motor - its smart motor technology takes turning to a new level. The
speed, vibration and load sensing work with the conditions and turning. The machine will reward skilled turning with
exceptional finish conditions. There is often no need for sanding. As you apply load (chisel pressure or depth of cut), the control
will sense the change in spindle conditions and compensate accordingly. Get a feel of the communication between yourself and
the motor turning by applying increasing force. The motor will respond by applying increased power to exactly maintain speed.
LOW SPEEDS 100-350: Select Hard Mode (see Special and Parameter settings)
Note – at low speeds 100- 350 rpm control of the chisel is important. At 250 rpm the motor still has good torque (in fact the
torque is more or less the same as at 400 or 1000) – but at low speeds there is a difference. The DVR is a unique type of motor in
that the control only supplies enough power to maintain the spindle at the commanded speed. It needs to sense the load from
the chisel and then it will apply power as needed. At very low speeds the chisel can move fast compared with the rotation of the
wood. The important thing is to have good control of the chisel and maintain steady cuts (using the same woodturning practices
that produce quality cuts and finishes). In this way surprisingly heavy cuts can be achieved. However, rapid or reckless use of the
chisel will be immediately sensed by machine and spindle will shut down and then automatically try a restart.
“Will The Machine Shut Down on Interrupted Cuts?”
Not as long as the cut is within the normal range of Woodturning cuts. An interrupted cut at slow rpm may cause a loss of
control of the chisel and a dig in may occur. A way to understand chisel feed rates is to consider that at 100 rpm, the work piece
has only rotated about 1 and a half turns in one second and 4 turns at 250 rpm. Considering that chisel feed or movement under
normal turning can be anything between 5 and 100mm per second at normal Woodturning turning speeds. At very low rpms it is
easy to move the chisel too fast for good cutting conditions. In general, low rpm is only used for special processes or conditions.
Speeds below 350 are generally not Woodturning speeds. The machine will operate down to 100 rpm but this is generally for
applying finishes and other applications.
LATHE TURNING SPEEDS
5000 - 3000
≤
Correct selection of turning speeds is important for safety and finish cut quality. It is important to take into account the fixing of
the work piece; it should be made as secure as possible. Various techniques are available for this consult books on the subject
and seek training opportunities. There are safety and out of balance considerations. Aim for a good balance in turning speed,
ensure good fixing and try to balance timber as much as possible before installing on lathe.
In general wood likes being sliced and if too low a speed is used the timber can "hammer" against the cutting tool, tearing fibers
and imposing large forces on the tool and work piece. This can often be dangerous, it is best to select a higher speed, the cut will
be smoother and less force is imposed on the work piece. It can be likened to a wood plane; if it is pushed very slowly, much
force is needed to break the fibers. If the plane is pushed at a higher speed, less force IS involved and a better cut results. Use
250 rpm when needed, but it is better turning at 400-600 rpm.
Learning Turning
The art and technique of turning is a subject beyond the scope of this instruction manual. It is recommended that you receive
hands-on instruction on lathe turning and/or refer to books and videos on the subject. For reference, some woodturning books

DVR MOTOR AND CONTROLLER
Overview
The DVR integrated motor drive system contains four main parts, the DVR Motor (stator and rotor built into the headstock), the
Rotor Position Sensor (RPS), the drive control board and the human-machine interface (HMI). The control board, RPS and HMI
make up the electronic control system of the drive.
The DVR motor is controlled by the control board which handles all the timing and power management to ensure an energy
efficient and powerful motor. The control board receives the commands from the user through the keypad and the HMI board,
and it provides useful feedback information such as the running speed and temperature, which is displayed to the user via the
LCD display.

Speed Profile
The DVR motor has built in speed control profiles, each with slightly different PI controller coefficients and performance
characteristics:
 SOFT - For light work at speeds lower than 500 rpm
 NORMAL (default) - Suitable for most work and is the default setting
 HARD - For heavy and/or ‘out-of-balance’ work at speeds lower than 500 rpm
To switch between the 3 speed control profiles
1. Go to Menu > Speed Profile
2. Press <F/R> to toggle between the different speed profiles.
NOTE: Changing the profile will change the Kprop and Kint parameter based on the predefined curve and the running speed. If
the user sets a new value for Kprop and Kint, this value will be constant until the lathe is powered off.
Lathe Settings
Display Size
There are two display size options that the user is able to select: Large and Normal. The user can toggle between the two modes
at any time by going to Menu > Lathe Settings > Display Size, and press the <F/R> key to toggle between the two modes.
1.
Large Number Display (Default)
The large number display was created to show the set speed using a larger portion of the screen, allowing the user to read the
speed at a distance. When the motor is running and display is in the large number mode, the running speed will be displayed
instead of the set speed on the LCD display.
2.
Normal Number Display
The normal display mode displays more information, such as the function of the F1 to F4 keys in the top line.

Assisted Braking
A new feature which has been introduced to the NOVA DVR Lathe range is the powered assisted brake. The braking function
provides some power to the motor after the <OFF> button has been pressed, this can be used to help stop the spindle and
reduce the freewheeling time when working with large or heavy work-pieces.
To enable or disable the assisted brake, go to the Menu > Assisted Braking and press the <F/R> key.
The braking function will activate when the parameter is enabled and the <OFF> button has been pressed OR when an error has
occured. It is important that the user does not press any buttons or try to use the HMI when the motor has the braking engaged.
WARNING! ENSURE THAT THE CHUCK IS FULLY SECURED TO THE SPINDLE. The braking force may unwind a chuck
which is not properly fastened.
E-Stop Braking
To ensure a quick stop when pressing the emergency stop button, the STOP button has the assisted braking enabled. This
braking can be turned ON and OFF independently without affecting normal reset braking.
Idle=Auto Off
A new feature introduced in the Galaxi Lathe is the automatic shutdown of the lathe. When the feature is turned on, the idle
motor sensor monitors the load of the motor and checks if the user is currently turning. This feature works with or without a
workpiece attached to the spindle. If the operator is not turning the work piece or making any changes to the load on the motor
for 4 minutes, a warning will be displayed on the HMI display. If the warning has not been cleared and the motor has been
running idle for 5 minutes, the motor will automatically be shut down and a warning message will be displayed to the user.
When the warning message has been displayed to the user, the <F3> key can be pressed to turn off the idle motor sensing
motor feature; otherwise any key can be pressed to clear the message and wake up the lathe.
Vibration sensor
The vibration sensor will automatically shut down the lathe when a potential unsafe working condition has been detected.
Excess vibration could be caused by an unbalanced workpiece, unstable footing or incorrect speed selected. There are four
settings for the vibration sensor, these are Low, Med, High and Off. The settings can be adjusted in the Lathe Settings menu OR
by pressing F3 when the vibration sensor warning is displayed.
-
HIGH (default): this is high sensitivity setting, default setting on the machine. This default setting will shut down and
apply braking to stop the spindle when excess vibration is detected from imbalance in the work piece or excess speed.
This is a recommended setting.
-
MED: this is intermediate sensitivity setting. This setting will shut down and apply braking to stop the spindle when
excess vibration is detected from imbalance in the work piece or excess speed. When med sensitivity setting selected –
the operator must determine that working condition are safe.
-
LOW: this is low sensitivity setting. This setting will shut down and apply braking to stop the spindle when a mass of
vibration is detected from imbalance in the work piece or excess speed. When low sensitivity setting selected – the
operator must determine that working condition are safe. This is a NOT RECOMMEND SETTING.
-
OFF: The vibration sensor can be turned off by the user to prevent the motor from shutting off due to vibration. When
Off selected – the operator must determine that working condition are safe. This is a NOT RECOMMEND SETTING.
WARNING! It is recommended that the vibration sensor is used when turning. Please start motor with slower
speed for unbalanced work.
Wireless Remote
The wireless remote is an optional accessory for the NOVA GALAXI DVR 1644 Lathe. The wireless remote allows the lathe to
change speed and turn the motor on and off without having to use the HMI. The advantage of the remote is that the user is able
to start the lathe from the tail stock end of the machine.

CLEARING THE PAIR ID
If the user would like to disable the remote, the remote ID can be cleared
1. Go to Menu > Wireless Remote
2. Select Unpair Remote
3. Select Yes to confirm the ID clear, the remote ID should now be cleared
Motor Parameters
One of the advantages of the DVR motor is the sophisticated electronics and software which allows the control board to
constantly monitor and optimize the power of the motor. The various parameters of the motor can be modified and saved into
EEPROM memory.
NOTE: The parameters Kprop and Kint cannot be saved into the EEPROM memory because it is based on the speed profile
parameter.
The Factory Reset can be initiated at the bottom of this menu. See Factory Reset section for complete instructions and more

TROUBLESHOOTING GUIDE
Problem
Possible Cause and Solution
Excessive vibration.
Out-of-balance or large work piece. Reduce lathe speed to the lowest
speed possible and turn the work piece to a true circle. If you try adjusting
the speed up or down, you will find that it is easy to find speed points that
will minimize vibration, and that is one of the biggest advantages of DVR
technology.
Work piece is not held in the center. Check work piece mounting and
correct.
Work piece is not secure or held tightly enough. Check work piece
mounting.
Lathe incorrectly bolted to stand or bench. Refer to this manual for lathe
stand recommendations.
Non-stock stand or bench is not well constructed, too light, or not level on
the floor. Make sure stand is solidly constructed. Use sandbags to weigh
down the stand.
Faceplate or chuck running
out of true.
Dirt build-up on the rear of the faceplates or chuck. Clean off all build-up
and dirt. Faceplates and chucks must mount securely against the inner
bearing ring surface of the spindle.
Turning tools not sliding
smoothly across Toolrest.
Damaged surface on Toolrest face caused by sharp edged tools. File the
Toolrest using a fine smooth file and polish with extra fine sandpaper. Also
remove the sharp edges from the corners of turning tools.
Spur drive center or live
center not holding into the
spindle taper or quill taper
when turning.
Small end of Morse taper is damaged due to dropping or hitting. File or
polish away any damage. Check that inside of tapers have not been scored.
Grease or oil inside of Morse tapers. Wipe clean the inside of the tapers.
Insufficient pressure when installing the center. Use a quick, firm action by
hand to install a taper. Do not knock in using any solid object.

Problem
Display screen not on
Possible Cause and Solution
Is master switch on? Toggle master switch to "ON" position.
Check machine is plugged into wall socket and switched on.
Check that the wall switch plug is live by plugging in another power tool. If the
other power tool doesn't operate, check your board fuse.
Check the master fuse on the lower rear guard. Ensure machine unplugged
(see Additional safety rules at the front of this manual). If blown, replace with
the spare fuse that comes with the lathe. Do not replace with a higher amp
fuse.

<Flashing>
Press “OFF” button. Switch off computer by master switch, wait one minute,
and switch on again. Check that the spindle index is not engaged or if
something is preventing the spindle from turning. Note leaving the spindle
index unit in will not harm the motor; however, it will put some strain on the
index unit. It is likely that the spindle index will be left in from time to time,
but the motor is designed for this.
The optical sensors that give the spindle position feedback (‘Rotor Position’
State) are obscured, damaged or have been disconnected. Dust over a long
period of time may have settled on the sensors. First, spin the spindle by hand
to create a draught through the sensors. Re-try the motor. If the error
remains, with the power switched off and disconnected, remove the upperrear guard and remove any wood dust with a vacuum cleaner. Avoid getting
the nozzle too close to the electronics. After this step, dust may fall into the
Headstock, so suck the dust out through the vent at the front of the
Headstock under the spindle. Do this sequence a few times. Try blowing with
Vacuum or Air gun if available. Replace guard.
The computer has built in voltage condition and temperature sensors. If this
message appears, check the temperature of the lower section of the
headstock. If it is very hot, switch off the master switch and leave the machine
to cool down for a period. If the headstock is relatively cool, the computer
may have detected an under and over voltage from the mains power. Switch
off and try rebooting. The DVR has a high level of protection and is
intelligently checking conditions all the time.

Problem
Possible Cause and Solution
Tailstock and Headstock
center not lining up
correctly.
Bed incorrectly bolted to stand causing twist. Ensure stand and lathe bed are
correctly installed.
Headstock not returned to detent position after it has been rotated. Ensure
that the headstock is locked into detent position.
Tailstock Handwheel
hard to turn or will not
turn.
Quill lock is locked; unlock the quill lock. If necessary, lightly tap a block of
wood against the Handwheel handle. Tap the handle in a clockwise direction
as viewed from the tailstock end.
Build-up of dust and wood resin on the quill or inside of the Handwheel
thread. Remove, clean, and lubricate the quill and tailstock as described under
"Cleaning the Tailstock".
The Quill has been extended too far and is locked against the Handwheel.
Push the quill back into the tailstock when turning the Handwheel.
Tailstock quill
hard to move.
The quill is damaged; turn the handle to expose the quill and check for marks
along the quill, especially on the edges of the slotted keyway. Remove the
high spots with a smooth file and test the quill travel. Replace the quill if
necessary.
Tailstock/Toolrest/
Headstock not locking
correctly onto bed, or
tailstock not sliding
smoothly on bed ways.
For headstock/tailstock, check to make sure locking shaft/handle are fully
tightened. If locking shaft/handle does not lock tightly or headstock and/or
tailstock are still mobile, loosen applicable locking handles and tighten locking
nut underneath bed. Repeat test and correction steps as necessary.
NOTE: Do not overtighten nut or headstock and tailstock will be immobile.
For toolrest, check to make sure locking handle is fully tightened. If locking
handle does not lock tightly or toolrest is still mobile, loosen locking handle
and tighten locking bolt underneath bed.
NOTE: Do not overtighten bolt or toolrest will be immobile.
Dirty bed ways and underside of headstock / tailstock / toolrest body. Clean
bed ways and underside of body with a petroleum-based solvent.
Tailstock binds.
The inside of the bed has a high spot. File the area with a smooth flat file until
the tailstock moves freely.
The tailstock adjustment plate has a rough spot or a burr. Remove the
tailstock and file the plate with a smooth flat file.
Tailstock jumps at bed
section joints.
The machined flat surfaces are not flush. File the area with a smooth flat file
until the tailstock moves freely.
Remote Battery
Replacement.
If the battery fails, you can unscrew the 2 screws on the bottom of the remote
and replaced with a CR1632 battery.
NOTE: The remote will still be paired with or communicate with your NOVA
DVR Lathe after battery replacement.
