ensure the insert is bottomed out
in the chuck body before mounting
on the lathe.
2. For Both Insert & Direct Thread
model: Wind the chuck on the
lathe spindle until the chuck comes
firmly in contact with the
bearing/spindle shoulder with no
gaps between.
3.
Place red thread protector washer
into the M6 Threaded hole. Then
wind the M6 grub screw in position
and tighten
with M3 Allen head
wrench (provided) to
prevent the
chuck from loosening

YOUR SAFETY
Keep these instructions ina safe place for future reference.
WARNING: This chuck iscapable ofcontributing toserious injury (as with any other power
tool accessory) ifthis manual guidance isnot followed or ifit isused 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 to usethis chuck. Vocational school courses orother expert
tuition is recommended.
As with other work holding methods, an extremely cautious and sensible approach is
necessary. With the PRO-TEK G3 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 atall 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 if the 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 itisin 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 for wood 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 toholding area. Rotate
manually to make sure ofclearance before switching power on.
DUPLICATOR OR JIGS:Donotusechuck for work holding with aduplicator orjigs.
Safe Practice:
CHISEL USE: Use only hand held woodturning chisels toshape wood being held in chuck.
Use the recommended 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 notwear any loose clothing, neck ties, gloves, bracelets,
rings or other 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
of drugs, alcohol orany medication.
KEEP CHILDREN AND VISITORS AWAY: All children and visitors should be kept safe
distance from the work area.

SCREW CHUCK - WOODWORM SCREW
The woodworm screw (screw chuck) provides a convenient method for holding a bowl blank
tocut a recess tomount on the PRO-TEK G3 50mm (2in) jaws.
Jaws must be mounted on the chuck before the wood worm screw – See diagram
Open the jaw slide and insert the wood
worm screw in the centre hole of the
chuck.
Position the woodworm screw as shown
in illustration
.
Note:
All 4 flat sides of the wood worm
screw should be in contact with the flat
end of the jaw slides.
The wood worm screw is used to secure the wood to
cut either a recess or spigot on the open
‘face’ end.
Pre
-
drill a hole of size 8mm (5/16in) diameter with
19mm (3/4in) depth to mount the blank using the
woodworm screw.
The wood must be seated firmly and
flat against the top surface of the mounted jaws.
For
first stage rounding of bowl blanks; extra support can
be used with live centre support from the lathe
tails
tock. See full manual online for more details.

ACCURACY
The PRO-TEK Chucks are sample tested from each batch
and are made to run within the following tolerance limits
on the PRO-TEK 50mm (2in) jaws:
-
Maximum Face/Axial Runout: 0.08mm (0.0031 in)
-
Maximum Radial Runout: 0.15mm (0.0060 in)
However, wood is aflexible material with varying densities
and liable towarp while turning.
Under these circumstances pursuing accuracies asabove,
measured on the wood project clamped in the chuck, can be
very difficult toachieve. For most wood turning projects
there is usually little requirement to achieve such tolerances.
