Nova DVR SATURN Lathe Features at a glance
DVR Electronic drive
The Nova DVR SATURN lathe is unique. The DVR incorporates the motor built as part of the headstock,
the spindle and motor are one unit. The motor is almost maintenance free and designed with high
reliability. The Digital Variable Reluctance motor uses smart motor technology to provide an
incredibly smooth and powerful drive. This drive takes turning to a new level. The controller monitors
the spindle position constantly and maintains spindle speed very closely. Additional power is added
as it senses extra load from the tool.
Add on Bed System
A lathe that meets your woodturning needs your workshop space, and your pocket! Each segment is 20" or 510mmin length. This feature
appeals for many different reasons:
As a compact lathe (standard configuration) it is great for small turning workshop spaces.
As an extended lathe for those wanting to do extra-long spindles (beyond the traditional between center of most lathes) the Nova
DVR SATURN delivers big turning capacity.
As a bowl lathe for those just wanting to turn bowls.
Sophisticated Swivel Head
Swivel head lathes have many advantages:
•Space saving
•Allows the turner (not the machine!) to decide the most comfortable position for your turning
(saving you from back strain)
•Elimination of left-hand ‘outboard’ turning techniques and no extra outboard chucks and
faceplates are necessary.
There are a number of swivel head lathes available, but the Nova DVR SATURN has by far the most sophisticated, accurate and easy to
use swivel head on the market.
The Nova DVR SATURN lathe can be easily and quickly swiveled to any position (360 degrees). It can be solidly locked in any position
plus it has the added security of a detent pin lock at 0,22.5,45,90 degrees plus 315 (for left-hand use).
The swivel head turns, locks easily and has a very accurate detent position, to lock the spindle in line with the tailstock. The combination of
rigid Tailstock construction and detent pin delivers superb accuracy and is unique to the Nova DVR SATURN.
Solid Construction
Well proven design, the Nova DVR SATURN is made from
Cast Iron components for strength and rigidity. Added
features like the heavy duty TRIMAX triple bearing system
and special webbed bed design makes the lathe well
equipped to take heavy turning stresses.
The bed has been designed with vibration dampening
qualities - a solid 1/2" cross rib is positioned along the bed
unit, quickly dissipating any vibration as it travels down the
bed. The new powerful trapezoidal bed design delivers even
more vibration damping properties. All this combined with
cosmetically appealing, smooth flowing lines.
Cast iron has always been the material of choice for Woodlathe construction for its inherent mass and an excellent modulus of vibration.

ADDITIONAL SAFETY RULES FOR WOODLATHES
!
Warning! Failure to follow these rules may result in serious personal injury.
Important: ALWAYS BEFORE SWITCHING SPINDLE ON, CHECK SCREEN FOR CORRECT SETTING
1. DO NOT MODIFY OR USE LATHE FOR USES
OTHER THAN FOR WHICH IT WAS DESIGNED.
2. SEEK INSTRUCTION. If you are not thoroughly
familiar with the operation of woodlathes, obtain advice
from your supervisor, instructor, or other qualified
person. Instruction from a qualified person is strongly
recommended.
3. DO NOT OPERATE LATHE until it is completely
assembled and installed. Follow instructions and
recommendations.
4. FOLLOW ELECTRICAL CODES. Make sure wiring
codes and recommended electrical connections are
followed and that the machine is properly grounded.
5. 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.
6. DVR SATURN; Do not open the switch and rear
covers. Components can carry dangerous voltages
even when isolated from mains power.
7. DVR SATURN; 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.
8. WHEN SPINDLE REVERSE IS ENGAGED DO NOT
USE CHISELS OR CUTTING TOOLS - USE FOR
SANDING ONLY
9. 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.
10. 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.
11. DO NOT MAKE ADJUSTMENTS when the lathe or
work piece is turning. Make all adjustments with power
Off.
12. TIGHTEN ALL CLAMP HANDLES on the headstock,
tailstock, and tool rest before operating lathe.
13. EXAMINE WORK PIECE and glue joints before turning
to make sure it has no defects that would cause it to
break when turning.
14. DVR SATURN; ALWAYS CHECK CORRECT SPEED
IS SELECTED BEFORE SWITCHING ON SPINDLE
15. USE LOWEST SPEED when turning a new or
unbalanced work piece.
16. TURN AT RECOMMENDED SPEED. Always operate
the lathe at the recommended speeds. Consult this
manual for suggested speeds.
17. 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 tool rest.
18. 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 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 SPINDLE 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.

Setting Up Your Workshop
Workshop Requirements
Consideration
Recommendation
Lathe location
Locate the Nova DVR SATURN close to a power source in an area with good lighting. Leave enough
clearance on all sides of the lathe; allow for motor clearance when the headstock is swiveled. Other
machines in your shop should not interfere with the operation of the lathe.
Lighting
Your shop should have adequate lighting. The work area of the lathe should be well lit; there should not be
shadows cast on your work. If possible, locate near a window. A portable spotlight may be helpful.
Electrical
The Nova DVR SATURN requires the appropriate power outlet nearby to power the motor. Wiring and
outlets should adhere to local electrical codes. If in doubt, seek advice from an electrician. Minimize use of
extension cords. See "Connecting to power" section for Surge Protector requirements.
Ventilation
Your shop should be adequately ventilated. The degree of ventilation will vary based on the size of the shop
and the amount of work done. The use of dust collectors and filters will minimize risks to your health.
Lathe Stand Recommendations
A sturdy and rigid stand is required so that the Nova DVR SATURN Woodlathe can deliver optimum performance. A common flaw with
many woodlathe installations is an inadequate stand for the lathe. The larger the size of your turnings, the greater the importance of the
lathe stand design.
Consideration
Recommendation
Lathe Height
from floor
The height of the stand should locate the centerline of the lathe spindle at the elbow height of the turner.
(illustration next page)
Stand Top
The stand top should be flat so the lathe does not twist when it is bolted down. Check for any gaps
between lathe feet and stand top before bolting down. Shim and prepare stand as necessary.
Stand Weight
The stand should have enough weight and mass so that it doesn't move when turning large work pieces,
and so that the stand can absorb vibrations. A lathe stand's stability can be improved by weighing it
down with sand bags on a lower shelf.
Stand Legs
The stand should sit level on the floor and not rock.

115-0917-010 xii
Example of Shop-made Lathe Stand
This has been designed with economy of space in mind. Heavier sections, wider rails and gussets on the
corners are encouraged. For stability and vibration dampening, it is highly recommended that the base is filled
with sand.

Assembling the Nova DVR SATURN
Warning! Seek help when moving the NOVA DVR Saturn lathe and its heavier components to help avoid risk of injury. Read
and understand the contents of this manual and recommended procedures before attempting to assemble or operate the Lathe or
its parts. DO NOT CONNECT POWER ON LATHE UNTIL FULLY ASSEMBLED.
1. Unpack the lathe and components from the shipping container. This is best done by cutting down the
sides of the box to expose the lathe
2. Clean any parts coated with rust preventative with a cloth moistened with a petroleum-bases solvent or
cleaner, such as paint thinner. Coat the lathe bed with paste wax.
Nova DVR SATURN Components After Unpacking
Assembling the Bed and Legs
3. Attach legs to bed using 6 supplied bolt M12 screws & spring washers and 2 supplied bolt M10 screws
and spring washers.
4. Once legs are fastened to bed, bed weight can be carefully placed on legs; screws must be fully tightened
down before further assembly.

115-0917-010 14
Installing the Headstock Lock Pin and Handles
5. Remove the plastic shipping tube from headstock base.
Immediately screw the Headstock Lock Pin into the
threaded hole at the bottom of the headstock. Insert the
operating bar into the hole in the Lock Pin and firmly tighten
the Lock Pin to lock the headstock in position; then remove
the operating bar.
Note: When the pin is fully engaged, the groove machined into
the pin furthest from the thread should line up with the edge
of the hole in the casting. By doing this the pin will be
engaged in the hole of the swivel pin.
6. Loosen the Lock Pin 1 –2 turns. Push the Headstock
Release Handle down and rotate the Headstock so the
spindle points to the tailstock and lines up parallel to the
lathe bed. Tighten lock pin again.
Note: Do not use excessive force when tightening the Lock Pin.
Important note:
Swiveling the headstock before inserting the lock pin may
result in the tapped hole on the Swivel pin becoming
misaligned.
7. Assemble the handles:
Note: Some handles may come pre-assembled.
Tool Rest Clamp Handle -
Insert the rod through the handle and screw the ball
knobs onto each end of the rod.
Tool Slide Clamp Handle –
screw the lock handle into the tool slide.
Tailstock Clamp Handle –
screw the lock handle into the tailstock.
Adding an Extension Bed
Each cast iron extension bed adds 510mm (20in.) to
the lathe’s capacity to turn between centers.
1. Clean the joining ends of both bed sections with a
petroleum-based solvent. Make sure there are no
dents or burrs on either mating surface. Remove
burrs and high spots with a smooth file.
2. Screw in cap screws tight.
3. Secure the bed sections together with four
M12x30 cap screws using a 10mm Allen wrench.
It may be necessary to move the lathe so the cap
screws can be reached with the wrench from the
bottom of the bed.
!
Warning!
Do not use a metal hammer to pound on the extension bed. This may damage the bed, affect accuracy and
tailstock action, and may prevent you from adding another extension bed.
4. Bring the Tailstock along until it is on top of the join area where the bed extension face meets the lathe bed face. The bed extension
may require manipulations up-and-down and sideways in order for the Tailstock to fit.
5. Check that the tool slide and tailstock move freely over the mating joint and also over the full length of the add-on extension. If there
is a ridge between the two mating surfaces then repeat steps 1 - 4 again, use a smooth file to file the surfaces flush.
6. Follow the suggestions under "Mounting the Lathe to a Support Surface".

15 115-0917-010
Mounting the Lathe to a Supporting Surface
1. Place the lathe on the stand top. Locate the front and left corner of the lathe approximately 25mm (1in.) from the corner edge of the
stand top. This provides a comfortable reach when turning and allows the optional outrigger unit to be easily installed.
2. If necessary, mark the six hole locations on the top and drill M12 holes.
3. Place a spirit level along the top of the lathe bed. Any movement of the bubble as the lathe is secured, indicates a twist on the bed.
For the lathe to operate correctly the bed must not twist; if necessary, use shims between the bed and stand top.
4. Use bolts of suitable length (not included) to secure the lathe. Tighten the two headstock bolts first, then the two tailstock bolts, and
finally tighten the last two bolts on top.
5. The two M10 threaded holes underneath the outrigger end of headstock can be optionally used (making a total of 8 bolt positions).
Ensure that the bolts are metric M10 x 1.5mm pitch and correct length to ensure that the bolt does not bottom the threaded hole
which could potentially damage casting.
Connecting to Power
The power cord should be 3-wire, having a grounding conductor and a grounding plug. The plug must be plugged into a matching outlet
that is properly installed and grounded in accordance with local electrical codes.
The DVR SATURN can run on either 115v or 220v ~ 240v, but the lathe will require correct plug for the selected voltage. If the lathe is
purchased in USA, it will already be setup for 115v operation. All other countries are preset for 220v ~ 240v.
!
Warning!
Improper connection of the motor can result in a risk of electrical shock.
If it is necessary to use an extension cord, the cord should be grounded. Use the correct wire size for the extension cord, for a given cord
length, to avoid power loss and over-heating.
IMPORTANT:
A Surge Protection Device rated to at least 15 amps - for USA and Canada, other countries 10 or 15
amps - must be used to protect the DVR electronics from electrical spikes or surges, similar to those
used on most Home PC's. Ground Fault Interrupters (GFI's) or Residual Current Detectors (RCD's)
are helpful and are a recommended protection device for any power tool. They can be used in
conjunction with a DVR lathe. Note some makers of GFI may not be compatible

DVR Variable Speed Controller
The NOVA DVR drive is a unique type of drive system where the motor and controller interact with one another. The motor provides data
to the controller about its positon and load condition. Controller then processes the information sent from the motor to deliver power to the
motor for optimal performance and minimal losses.

Special Parameters and Settings
!
You may wish to change the stabilization setting from time to time depending on the type of work piece you are working on.
You have 3 options preset for you:
1. SOFT: For light work at speeds lower than 500 rpm
2. NORMAL: Suitable for most work and is the default setting
3. HARD: For heavy and/or ‘out-of-balance’ work at speeds lower than 500 rpm
a)
Press <OFF> if necessary
b)
Press <PROGRAM> (key #6 on diagram). The stabilization setting will be displayed. The default setting is NORMAL.
c)
Press <SELECTOR> (key #7 on diagram) to toggle between the 3 options as mentioned above
NOTE:
Pressing <MODE> (key #8 on diagram) allows the user to change the parameter settings in more detail. This breaks it down into
Proportional (Kprop) and Integration (Kint) settings which make up the PID control of the DVR. The 3 options of SOFT, NORMAL
and HARD have been preprogrammed for your convenience and are balanced for optimum output. To clear special settings and
return to default --- switch off computer at the master switch.
d)
Press <PROGRAM> button to return to ready state. (Ready to start mode).
While the machine is running, if you push Mode (8) the screen will display various diagnostics. Operation of the machine is not effected.
Each time mode is pressed a different screen will show. This area is only used for advanced programming functions.
Auto safety-- If the power is lost to the machine, when power is restored the computer will reboot but the machine will not start until the
‘ON’ switch is pressed. Remember to correctly select speed if different from Default speed.
Warning: Do not push several keys together as special coded combinations of keys open diagnostic and service functions.
Some of these disable control and protection functions. If an unfamiliar screen is displayed, switch off the computer and leave
for one minute before rebooting.
If the DVR hasn’t been used for some period (over one month) it is helpful to switch the unit on 30 – 60 minutes before use

New functions in the control panel:
Two new features have been implemented in the latest iteration of the DVR SATURN Lathe, these are “Recommended Turning Speeds
Guide” and the “Powered Assisted Braking”
Recommended Speed Guide
The recommended turning speed is a simple guide to advise the turner on the turning speed based on the size of wood and the type of cut
the turner wishes to perform.
How to use the speed chart:
1. Press the <Program P> button until the “Speed Guide” page appears
2. Press the <Selector E> button to enter the speed chart
3. Select the type of cut (Finish/Shape Cut or Rough Cut) by using the <UP RPM> or <DOWN RPM> button and confirm by
pressing the <Selector E> button
4. Select the diameter of the work piece by using the <UP RPM> or <DOWN RPM> button and confirm by pressing the <Selector
E> button
5. Press the <Program P> button to set the recommended speed as the current running speed
IMPORTANT NOTE: The “Recommended Speed Guide” only provides a rough estimate of the speed which should be used.
The user should adjust the speed value based on:
The shape, balance and weight of the work piece
Type of cut which the wood turner is going to perform
The experience of the wood turner
Powered Assisted Braking
The powered assisted braking feature can be used to help slow large work pieces when the user has pressed the “OFF” button.
How to use the Powered Braking:
1. Press the “Program P” button until the “Assisted Braking” page appears
2. Press the “Selector E” button to ENABLE or DISABLE the power braking
3. IF the braking mode is enabled, the motor will energize the motor when the user has pressed “OFF” to help slow down the
spindle
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.
-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.
Please pressing any key to continue when the vibration sensor warning is displayed.
