YOUR SAFETY
Keep these instructions ina safe place for future reference.
WARNING: This chuck iscapable ofcontributing to serious injury (as with any other
power tool accessory) if this manual guidance is not followed orif it is used improperly
on the lathe. Read and understand also the lathe owner's manual. Ifyou do nothave a
manual, contact the supplier ofyour lathe toobtain one before using the lathe and
chuck. User must be professionally trained tousethis chuck. Vocational school courses
or other expert tuition is recommended.
As with other work holding methods, an extremely cautious and sensible approach is
necessary. With the PRO-TEK SUPERNOVA2 Chuck,it is not possible to give exact
directions as to the amount of tightening pressure required for adequate work holding
or approved chisel cutting techniques. Follow closely strict guidelines in this manual
for different jaw types on wood blank diameters and length, plus strictly follow
recommended lathe speeds.
Safe Operation:
Eye Protection: Woodturning operations can result in objects being thrown into your
eyes which can result insevere eye damage. Protective eye wear must be used at all
times. Everyday vision wear is not protective eye wear. We recommend a full-face shield.
Always wear eye protection which complies with current ANSI Standard Z87 (USA)
Noise Protection: Use ear plugs oreardefenders. Particularly ifthe noise exceeds 85dB.
Exposure tohigh levels ofnoise can lead to hearing problems.
Dust Protection: Use respiratory protective equipment (dust mask, portable respirator
device). Exposure to high levels of irritating dust when turning or sanding hardwoods,
soft woods and manufactured composite boards (MDF) can result in serious health
problems. In addition, adequate workshop dust extraction must be used.
Chuck is properly secured on lathe spindle: Follow mounting instructions for your lathe
for faceplates and other spindle fixtures. Do not rotate chuck under power unless
workpiece is firmly clamped.
WARNING: LATHE SPEED: Excessive speed is a serious lathe hazard. Always turn at the
slowest speed possible. Ideal 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 recommended lathe speeds to
size of wood blank are known. In addition, you must strictly follow the maximum speed
limits set out in the operating section of this manual. Do not exceed them under any
circumstances.
CHECK WORKPIECE: Examine wood blank carefully before mounting on chuck/lathe.
Only mount wood that hasno cracks, splits, holes orany other weaknesses (e.g. rotten
or spongy sections). Do not use poorly jointed or laminated wood. Irregular or outof
balance stock needs tobe turned at the slowest possible speed until itis in balance.
Make sure wood is clamped firmly. Follow mounting instructions for different gripping
modes and jaw types. In the expansion mode do notuseundue force orjaws may split
the wood.
Do notexceed maximum guidelines in this manual forwood blank diameters/length set
out in this manual for different modes and jaw types.
Check wood is securely held in chuck, before operation. Check grip by vigorously
wrenching wood blank back and forth. Ifany loosening occurs, re-examine holding area
for adequate grip (Following mounting guidelines) and any damage to holding area.
Rotate manually to make sure ofclearance before switching power on.
DUPLICATOR OR JIGS:Donotusechuck for work holding with a duplicator orjigs.
Safe Practice:
CHISEL USE: Use only hand held woodturning chisels toshape wood being held in chuck.
Use therecommended chisel for the job. Use safe and commonly approved techniques.
WARNING: Never attempt to place hands on a moving chuck on a lathe. Wait for the
chuck to come to a complete stop before hands are anywhere near the chuck. Trying to
grab at a moving chuck could result in SERIOUS INJURY. Jaw Slides: For safe operation do
not extend the jaw slides beyond the chuck body under any circumstances.
Wherever possible stand to one side ofthe revolving wood.
WEAR SUITABLE CLOTHING: Do not wear any loose clothing, neck ties, gloves, bracelets,
rings orother jewellery that could get caught in moving parts. Wear protective hair
covering tocontain long hair.
DRUGS, ALCOHOL, MEDICATION: Do notoperate chuck orlathe while underthe
influence ofdrugs, alcohol or any medication.
KEEP CHILDREN AND VISITORS AWAY: All children and visitors should be kept safe
distance from the work area.
