Welcome

Thank you for purchasing our NOVA PRO-TEK G3 Geared Chuck. It is a new addition

to our NOVA woodturning chuck range with advanced features to enhance your

chuck use. It provides a versatile and easy method for fast and secure work holding

for all face turning –bowls, platters, egg cups, vases, boxes, goblets, and an endless

variety of similar projects.

The NOVA PRO-TEK G3 Chuck combines the best features of our NOVA Chuck, G3

Chucks, and similar woodturning chucks (wide jaw movement, quick two-way grip)

with the advantages of our latest technology and inNOVAtion.

As a valued customer, we would be pleased to hear from you and how you found

your PRO-TEK G3 Chuck. Any comments on the chuck or accessory ideas would be

very welcome so that we can continue to offer what we believe is the best

woodturning chucking system available.

Benefits of NOVA PRO-TEK G3 Chuck

•Premium rust resistant nickel plating, ideal for turning green wood.

•Stronger and more versatile 50mm/2” PRO-TEK Jaws with an improved dovetail

AND serrated profile for maximum control. The unique woodworking dovetail

profile pulls the project into the chuck and holds round and square blanks more

firmly.

•Precision laser etched jaw numbering allowing ease of jaw and slide alignment,

positioning and change out.

•Upgraded 6 point star fasteners exerting more torque with ease, offering better

holding power and minimizing strip out for longer life.

•Jaw fastening wrench upgraded to T-bar handle (from hex wrench) for reduced

stripping; and enabling quicker tightening of screws which are easier on hands.

•Intuitive clockwise scroll rotation for ease of use.

•CNC precision machined for unparalleled tolerances and accuracy.

•Powerful geared grip delivers tremendous slide holding power.

•Copper-infused, precision-cast jaw slides for effortless movement and

resistance to wear and tear.

•Single-handed operation offers fast and convenient mounting for your project:

quicker setup equals more time to turn.

•Rotation arrow for easy reference and fast opening and closing action.

•Auto safety stop feature to keep Jaw slides from protruding past the chuck

body.

•Jaw mounting profile is cross-compatible with all NOVA chucks.

•NOVA’s Spindle Adaptor system — fit your NOVA Insert chuck to various lathe

spindle threads.

•Safe Lock Woodworm Screw included for fast mounting of rough material.

•Upgraded chuck key with sliding T-bar handle.

•FREE! NOVA microfiber workshop towel (11.5"/29.5mm x 10.5"/27.5mm) to

help keep your chuck and jaws well maintained.

•6 Year Full Replacement Warranty —Best in Market!

All NOVA jaws are specially designed to provide maximum grip expanding into a

mortis/recess or contracting around wood tenons/spigots of varying sizes and

shapes. NOVA chucks can instantly swap from the expansion mode to the contracting

mode, with no adjustments or extra fittings being necessary. Any mortis/recess or

tenon/spigot size can be selected between the minimum and maximum range of the

jaws. The jaw slides (accessory jaws removed) can be used to grip small

tenons/spigots.

ACCURACY: The PRO-TEK G3 Chucks are sample tested from each batch and are made

to run within the following tolerance limits measured on the 50mm (2”) PRO-TEK

Jaws:

Face/Axial Runout (X Axis) Maximum: 0.08mm (0.0031 inch)

Radial Runout (Y Axis) Maximum: 0.15mm (0.0060 inch)

Testing is performed with the chuck mounted with a standard NOVA threaded insert.

However, note that wood is an elastic material –with different densities even in the

same piece, and liable to warp out of place while turning. This is a part of the beauty

and appeal of working with wood. However, under these circumstances pursuing

accuracies (as above) with mounted wood can be difficult to achieve. For most

woodturning situations (with some expectations) there is little need to achieve such

tolerances.

General Health and Safety Guidance

ATTENTION: Please carefully read and understand the instructions in this manual

before assembly, installation and use of your PRO-TEK G3 Chuck.

Keep these instructions in a safe place for future reference.

WARNING: This chuck can contribute to serious injury (as with any other power tool

accessory) if this manual guidance is not followed or if it is used improperly on the

lathe. Read and understand 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 or

other expert tuition is recommended. NOVA also recommends joining a woodturning

club.

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 in severe eye damage. Protective eye wear must always be

used. Everyday spectacles are 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 or ear defenders. Particularly if the noise exceeds

85dB. Exposure to high levels of noise 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. 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 has no cracks, splits, holes, or weaknesses (e.g. rotten or

spongy sections).

Do not use poorly jointed or laminated wood. Irregular or out of balance stock needs

to be turned at the slowest possible speed until it is in balance.

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.

As above Do not exceed 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. 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.

DUPLICATOR OR JIGS: Do not use chuck for work holding with a duplicator or jigs.

Safe Practice:

CHISEL USE: Use only handheld woodturning chisels to shape 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 of the revolving wood.

WEAR SUITABLE CLOTHING. Do not wear any loose clothing, neck ties, gloves,

bracelets, rings, or other jewelry that could get caught in moving parts. Wear

protective hair covering to contain long hair.

DRUGS, ALCOHOL, MEDICATION. Do not operate chuck or lathe while under the

influence of drugs, alcohol, or any medication.

KEEP CHILDREN AND VISITORS AWAY: All children and visitors should be kept safe

distance from the work area.

Make workshop childproof with padlocks, master switches, or by removing starter

keys, or have machines fitted with a Striatech drive system using the password lock

feature
