YOUR SAFETY
IMPORTANT PLEASE READ & UNDERSTAND THIS INFORMATION BEFORE
USING YOUR SUPERNOVA2CHUCK
DANGER: THIS CHUCK IS CAPABLE OF CONTRIBUTING TO SERIOUS INJURY, AS WITH
ANY OTHER POWERTOOL ACCESSORY, IF USED IMPROPERLY ON THE LATHE.
Before using the SuperNova2Chuck, read and understand this instruction manual. Read
and understand also the lathe owner's manual. If you do not have a manual, contact the
supplier of your lathe to obtain one before using the lathe and Chuck.
User must be professionally trained to use this chuck. Vocational school courses recommended.
As with other chucking methods, an extremely cautious and sensible approach is necessary. With
the SuperNova2Chuck it is not possible to give exact directions as to the amount of tightening
pressure required for workholding. Follow closely strict guidelines in this manual for different jaw
types on wood blank diameters and length, plus turning speed.
BEFORE USING SUPERNOVA2CHUCK MAKE SURE THAT -
• 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.
• Chuck is properly secured on lathe spindle. Follow mounting instructions for your lathe for
faceplates and other spindle fixtures.
• For safety, DO NOT ROTATE CHUCK UNDER POWER WITHOUT WOOD BEING GRIPPED.
• WARNING: 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.
• 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.
• EXAMINE WOOD CAREFULLY. ONLY MOUNT WOOD THAT IS SOUND, If any cracks, splits,
or weakness is found in wood - DO NOT MOUNT ON CHUCK. 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.
• 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.
• Do not exceed maximum guidelines in this manual for wood blank diameters/length set out in
this manual for different modes and jaw types. DO NOT USE WITH ANY COPYTURNER
OPERATIONS
• 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.
WARNING –NEVER ATTEMPT TO GRAB AT THE MOVING CHUCK ON A LATHE. Wait for the
chuck to come to a complete stop before putting your hands anywhere near the chuck. Trying to
grab at a moving chuck will result in SERIOUS INJURY.
• WARNING FOR SAFE OPERATION. DO NOT EXTEND JAW SLIDES BEYOND CHUCK
BODY UNDER ANY CIRCUMSTANCES. ONLY OPERATE CHUCK WITH JAW SLIDE STOP
SCREW IN PLACE AND TEST TO MAKE SURE IT IS ADJUSTED OUT TO STOP JAW SLIDE.
• This prevents jaw slides from dislodging from chuck.
• Irregular or out of balance stock needs to be turned at the slowest possible speed until it is in
balance. For use on outboard/left-hand rotation - MAKE SURE INSERT IS SECURELY LOCKED
WITH GRUBSCREW BEFORE USE. Use only hand held woodturning chisels to shape wood
being held in chuck.
