General Safety Rules
Warning! Failure to follow these rules may result in serious personal injury.
DANGER: THIS CHUCK IS CAPABLE OF CONTRIBUTING TO SERIOUS INJURY, AS WITH ANY OTHER POWERTOOL ACCESSORY, IF
USED IMPROPERLY ON THE LATHE. ONLY USE GENUINE NOVA CHUCKS, NOVA PARTS AND ACCESSORIES. USE OF ANY OTHER
CHUCK BRANDS OR PARTS ON OTHER CHUCK BRANDS MAY BE UNSAFE AND WILL VOID WARRANTY.
FOR YOUR OWN SAFETY, READ THE MANUAL
BEFORE OPERATING THE TOOL. Learn the machine’s
application and limitations plus the specific hazards
peculiar to it.
1. ALWAYS USE A FULL FACE SHIELD-Strongly
recommended (must comply with ANSI STANDARD
Z87.1 -USA) Everyday eye-glasses 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.
2. 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.
3. USE EAR PROTECTORS. Use ear muffs for extended
period of operation. Use muffs rated to 103 DBA LEQ (8
hour).
4. 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.
5. KEEP WORK AREA CLEAN. Cluttered areas and
benches invite accidents. Build up of sawdust is a fire
hazard.

Additional Safety Rules for Chucks
Warning! Failure to follow these rules may result in serious personal injury.
DO NOT MODIFY OR USE LATHE FOR USES OTHER THAN
FOR WHICH IT WAS DESIGNED.
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. MAKE SURE WOOD is securely clamped in the chuck before
turning it on
3. EXAMINE WORK PIECE and glue joints before turning to
make sure it has no defects that would cause it to break when
turning.
4. CHECK SET-UP with power Off. Examine the set-up carefully
and rotate the work piece by hand to check clearance before
turning on power.
5. 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.
6. DO NOT MAKE ADJUSTMENTS when the lathe or work
piece is turning. Make all adjustments with power Off.
7. TIGHTEN ALL CLAMP HANDLES on the headstock,
tailstock, and toolrest before operating lathe.
8. USE LOWEST SPEED when turning a new or unbalanced
work piece.
9. USE CORRECT SPEED for turning the wood blank as wood
speed will vary depending on diameter.
10. KEEP TOOL ON TOOLREST. Tools should remain on the
toolrest whenever the tool is engaged in contact with the work
piece.
11. DO NOT ROTATE CHUCK under power without wood being
gripped and securely tightened in the chuck.
12. USE CORRECT LATHE TOOLS. Do not use spindle turning
chisels for faceplate mounted work, and vice versa. Spindle
turning tools used for faceplate turning may grab the work piece
and pull the chisel from your control.
13. DO NOT POUND WORK PIECE into headstock drive (spur)
center while attached to the lathe when turning between centers.
Pound the drive center into the work piece with a soft mallet
before installing it between centers in the lathe.
14. 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.
15. FASTEN STOCK SECURELY BETWEEN CENTERS. Make
sure the tailstock is locked before turning onthe power.
16. NEVER LOOSEN TAILSTOCK spindle or tailstock while work
piece is turning.
ALWAYS WEAR EYE PROTECTION WHICH COMPLIES WITH
CURRENT ANSI STANDARD Z87.1 (USA). WE RECOMMEND
THAT A FULL FACE SHIELD BE USED AT ALL TIMES.
17. MAKE SURE CHUCK IS SECURED properly on lathe spindle.
Follow mounting instructions for your lathe for faceplates and
other spindle fixtures.
18. REVERSE OPERATIONS are primarily used for light sanding
and finishing operations. To use the chuck in reverse for light
sanding and finishing, the chuck needs to be locked to the lathe
spindle, using the grubscrew provided. Before engaging in any
reverse operations, check the grubscrew is fully locked and in
place, according to instructions. Do not use the chuck in reverse
for turning.
19. DO NOT ROTATE CHUCK UNDER POWER WITHOUT WOOD
BEING GRIPPED.
20. EXCESSIVE SPEED IS A SERIOUS LATHE HAZARD.
ALWAYS TURN AT THE SLOWEST SPEED POSSIBLE. Speed
will vary with wood blank size. The larger the blank the slower
the speed. Consult your lathe manual or lathe information plate
for speed guidelines.
21. DO NOT ATTEMPT TO USE THE CHUCK UNLESS THE
LATHE SPEEDS ARE KNOWN, YOU MUST STRICTLY
FOLLOW THE MAXIMUM SPEED LIMITS SET OUT IN THE
OPERATING SECTION OF THIS MANUAL. DO NOT EXCEED
THEM UNDER ANY CIRCUMSTANCES.
22. DO NOT TURN IN REVERSE. Do not use these jaws in chucks
for reverse turning operations. Light reverse operations i.e.
sanding are allowed and speed is not to exceed 2,000rpm in
reverse.
23. EXAMINE WOOD CAREFULLY. ONLY MOUNT WOOD THAT
IS SOUND, if any cracks, splits, or weakness is found in wood -
DO NOT MOUNT ON CHUCK.
24. DO NOT MOUNT ANY WOOD THAT IS LIKELY TO BREAK UP
DURING TURNING (E.G. ROTTEN OR SPONGY WOOD). DO
NOT USE POORLY JOINTED/LAMINATED WOOD.
25. IRREGULAR OR OUT OF BALANCE STOCK needs to be
turned at the slowest possible speed until it is in balance.
26. MAKE SURE WOOD is clamped firmly. Follow mounting
instructions for different gripping modes and jaw types. In the
expansion mode do not use undue force or jaws may split the
wood.
27. DO NOT EXCEED MAXIMUM guidelines in this manual for wood
blank diameters/length set out in this manual for different modes
and jawtypes.
28. DO NOT USE WITH ANY COPYTURNER OPERATIONS
29. CHECK WOOD IS SECURELY HELD in chuck, before
operation. Check grip by vigorously wrenching wood blank back
and forth. If any loosening occurs, re-examine holding area for
adequate grip (Following mounting guidelines) and any damage
to holding area. Rotate manually to make sure of clearance
before switching power on.
30. WARNING FOR SAFE OPERATION. DO NOT EXTEND JAW
SLIDES BEYOND CHUCK BODY UNDER ANY
CIRCUMSTANCES

INFINITY Quick Change
Note that Inserts, accessory jaws etc are fully interchangeable between the NOVA Infinity, Nova, SuperNova, Titan
II and SuperNova2 Chucks. However, additional Retro Fit Kit (SKU 8200) will need to be purchased to use your
old NOVA chuck accessory jaws on the new NOVA Infinity Quick Change Jaw Slides.
ONLY USE GENUINE NOVA CHUCKS, NOVA PARTS AND ACCESSORIES. USE OF ANY OTHER CHUCK
BRANDS OR PARTS ON OTHER CHUCK BRANDS MAY BE UNSAFE AND WILL VOIDWARRANTY.
UPGRADE KIT
SKU 8100
Kit containing 4 Infinity Jaw Slides, enabling you to replace your old existing NOVA chuck jaw slides (Precision
Midi, G3, SuperNOVA2 with the Infinity quick change technology, giving you access to Quick Change technology
and all the exciting NOVA Infinity Quick ChangeAccessory Jaws.
SKU 8120
As above but for specifically for the NOVA Titan II Chuck.
RETRO FIT KIT
SKU 8200
Kit containing 4 jaw insert pieces, fitted to your Infinity Jaw slides, it enables you to fit your existing older NOVA
chuck accessory jaws to the Infinity jaw slides.
ACCESSORY JAWS
NOVA Infinity is a new system which offers innovative breakthroughs for chuck holding.
A quick change jaw key system fits to the Infinity Slides (patent app.) to form a powerful and secure ‘taper lock’
much stronger than the original jawscrew fastening system. Delivers more powerful holding with the big advantage
of jaws that can be changed out in less than 30 seconds.
The Infinity system also allows complete freedom in jaw design with no screw fastenings to limit jaw function.
The NOVA Innovation team were able to take a fresh look at jaw holding to help the woodturner to select the
appropriate jaw to enable the just the right shape and design for their work, no matter the size. A ‘freedom to
design’ was not possible with the original jaw series.
The Infinity jawseries approach is based around workholding solutions in areas such as bowl turning, spigot/tenon
turning, hollow forms, available in Bowl, Saw Tooth and Smooth Column Series.
CHUCKS
There are several models of the SuperNOVA2 Infinity Quick Change Chuck designed to meet various woodturning
requirements. Note that inserts, accessory jaws etc are fully interchangeable between the NOVA Infinity, Nova,
SuperNova, Titan, G3 and SuperNova2 Chucks. However, an Retro Fit (SKU 8200) will need to be purchased.
