GENERAL SAFETY RULES
PLEASE READ AND UNDERSTAND THESE SAFETY RULES BEFORE OPERATING ANY
OF THE ACCESSORY JAWS.
!
WARNING!The NOVA ACCESSORY JAWS ARE DESIGNED FOR USE ON
TEKNATOOL CHUCKS ONLY. THEY ARE NOT DESIGNED TO FIT AND CANNOT BE
USED WITH ANY OTHER CHUCK. TO DO SO COULD CAUSE A MALFUNCTION AND
RISK OF SERIOUS INJURY. IF YOU ARE UNSURE OF THE USE OR APPLICATION OF
ANY OF THESE ACCESSORY JAWS BEFORE USING CONTACT YOUR RESELLER OR
TEKNATOOL DIRECTLY.
IMPORTANT:READ VERY CAREFULLY THE SAFETY SECTION IN THE TEKNATOOL
CHUCK MANUAL BEFORE OPERATION AND FOLLOW CLOSELY THE SAFETY RULES
OUTLINES IN THIS JAW MANUAL.
CONSULT RELEVANT OPERATIONAL SECTIONS OF THE TEKNATOOL CHUCK MANUAL
BEFORE USING JAWS.
SOME SAFETY DIRECTIONS ARE PERTINENT ONLY TO A CERTAIN JAW SET. ANY
ADDITIONAL SAFETY INFORMATION IS LOCATED IN THE TEXT OF THE RELEVANT
ACCESSORY JAW IN THE PAGES FOLLOWING.
DANGER: THIS CHUCK IS CAPABLE OF CONTRIBUTING TO SERIOUS INJURY, AS
WITH ANY OTHER POWER TOOL ACCESSORY, IF USED IMPROPERLY ON THE LATHE.
Before using the Teknatool chuck and accessory jaws, read and understand the instruction
manuals. Read and understand also the lathe 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 chuck and accessory jaws. Vocational school
courses are recommended. As with any other chucking method, an extremely cautious and
sensible approach is necessary. With the Teknatool chuck it is not possible to give exact
directions as to the amount of tightening pressure required for work holding. Follow closely
strict guidelines in this manual for different jaw types for wood blank diameters length, and
turning speed.
!

117-0815-0025
ALWAYS WEAR EYE PROTECTION WHICH COMPLIES WITH CURRENT ANSI
STANDARD Z87.1 (USA). WE STRONGLY RECOMMEND THAT A FULL FACE SHIELD IS
USED AT ALL TIMES.
BEFORE USING THE TEKNATOOL CHUCK ACCESSORY JAWS BE SURE THAT:
WARNING!!! EXCESSIVE SPEED IS A SERIOUS LATHE HAZARD. ALWAYS
TURN AT THE LOWEST SPEED POSSIBLE. Speed required will vary with wood
blank size. The larger the blank the slower the speed. Consult your lathe manual.
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 OPERATIONAL SECTIONS OF THIS MANUAL. DO NOT EXCEED
THEM UNDER ANY CIRCUMSTANCES.
EXAMINE WOOD CAREFULLY. ONLY MOUNT SOUND WOOD. If any cracks or
weakness is found in the wood –DO NOT MOUNT IN CHUCK OR IN ACCESSORY
JAWS. DO NOT MOUNT WOOD THAT IS LIKELY TO BREAK UP DURING
TURNING (E.G. ROTTEN OR SPONGY WOOD). DO NOT USE POORLY
LAMINATED WOOD.
DO NOT EXCEED MAXIMUM GUIDELINES IN THIS MANUAL FOR WOOD BLANK
DIAMETER / LENGTH FOR THE DIFFERENT MODES OF OPERATION AND JAW
TYPES.
DO NOT EXTEND JAW SLIDES BEYOND CHUCK BODY UNDER ANY
CIRCUMSTANCES. ONLY OPERATE CHUCK WITH JAW SLIDE STOP SCREW IN
PLACE. This prevents jaw slides from dislodging from chuck. NOTE: SuperNova2
Chuck has automatic internal stop.
WARNING - MAKE SURE THAT IN EXPANSION MODE THAT THE AMOUNT OF
TRAVEL REQUIRED IS LESS THAN THE LIMIT OF THE STOP SCREW, OR
AUTOSTOP. DO NOT TRY TO FORCE CHUCK OPEN FURTHER.
ALWAYS TEST WORKPIECE IS GRIPPED SECURELY IN THE JAWS. BEFORE
OPERATION TEST BY WRENCHING WORKPIECE IN JAWS. IF ANY LOOSENING
OCCURS, RE-EXAMINE HOLDING AREA FOR ADEQUATE GRIP (following
mounting guidelines) AND ANY DAMAGE TO GRIPPING AREA.
MAKE SURE WORKPIECE IS CLEAR OF OBSTRUCTION BY MANUALLY
ROTATING WORKPIECE BEFORE SWITCHING POWER ON.

SAFETY
Consult the safety section of this jaw manual and also read the safety section of your
Chuck manual and be thoroughly familiar with the safety operation before using these
jaws.
PARTS PROVIDED:
4 Die cast Cole Jaw Segments
8 M6x20 Countersunk Screws
8 M6x16 Cheese Head (Slotted) Screws
8 Cole Jaw Rubbers
IMPORTANT INFORMATION!!!
METHOD OF FITTING FOR FIRST TIME USE
NOTE: EXTREME CARE SHOULD BE TAKEN. The locator ring on the back of the
Cole Jaws provides the accuracy of location. Care must be taken that this locator
ring is not damaged when the jaws are placed in the jaw slides.
1. With the chuck body flat on a bench, carefully place each Cole Jaw segment
in line with the holes.
2. Start screws so they have just begun to engage in threaded holes of the jaw
slides. Remember to first lightly oil or grease screws under heads before use
to prevent screws from locking onto jaw.
3. Gently rock the Cole Jaw segment from side to side until the locator ring on
the jaw segment is eased properly in the groove of the jaw slide. Look under

117-0815-0027
jaw segment to make sure the ring is properly seated in jaw slide groove.
Check for a gap between jaw slide and Cole Jaw segment –there should be
no light showing.IT SHOULD NOT BE RIDING UP ON THE EDGE OF THE
GROOVE!
4. Screws should first be wound down until heads just touch the jaws.
5. Starting with the inside screw, wind it ¼ to ½ a turn. Similarly wind outside
screws until screws are fully home. DO NOT OVERTIGHTEN.
6. Repeat procedure on all four segments.
Note: The four Cole Jaw die cast segments provided are all identical, so they can be
mounted in any sequence. Hence they are not numbered. It may be convenient to
number them 1-4 in clockwise sequence when mounted on the chuck so that they
can be put back in the same sequence each time. The standard mounting screws
that come with the Teknatool chucks can be used for this purpose. Extra screws can
be obtained by purchasing the “Nova Fastening Spares Kit”.
Check there is no light between jaw slides and add on jaw segments or that one or
more segments is not higher or lower than the others. If this is the case, repeat the
procedure as above.

SPECIAL INSTRUCTIONS FOR COLE JAW RUBBERS
WARNING!!!
DO NOT EXCEED 600 RPM WITH COLE JAWS OR 800 RPM WITH MINI
COLE JAWS IN ANY OPERATIONAL MODE.
OUT OF BALANCE STOCK MUST BE TURNED AT THE SLOWEST
SPEED POSSIBLE BELOW 600 RPM.
DO NOT ATTEMPT TO USE THESE JAWS IF YOUR LATHE DOES NOT
HAVE A USABLE SPEED OF 600 RPM OR BELOW.
MAKE SURE THAT JAW SLIDES DO NOT PROJECT BEYOND CHUCK
BODY WHEN JAWS ARE EXPANDED.
DO NOT STAND DIRECTLY OPPOSITE REVOLVING BOWL. STAND ON
ONE SIDE INSTEAD.
USE SPECIAL OPTIONAL WOODWORM SCREW DESIGNED FOR COLE
JAWS. THE NORMAL WOODWORM SCREW CAN NOT BE USED WITH
THE COLE JAWS.
THE 25MM AND PIN JAW SET CAN NOT BE MOUNTED ON THE MINI
COLE OR COLE JAWS.
OPERATIONAL MODES
A. Contracting and Dovetail Modes
Both the contracting and dovetail modes are available when the other
accessory jaw sets (e.g. 50mm, 75mm,100mm) are mounted onto the Cole
Jaws and used in the normal way. The longer M6x20mm screws (not
providedwith the Cole Jaws) must be used to secure the optional jaws to the
Cole Jaws. Follow the usual operational directions and safety requirements
for the particular jaw set used (e.g. 50mm, 75mm, 100mm).
THESE INSTRUCTIONS AND SAFETY REQUIREMENTS CAN BE FOUND
IN THE ASSOCIATED JAW INSTRUCTION BOOKLET.
B. Re-Chucking Using The Cole Jaw Facility
The Cole Jaw segments can be mounted onthe chuck by themselves without
the use of any other jaw sets. Normal M6x10mm Countersunk screws
provided with your Teknatool chuck to mount the other accessory jaw sets
can be used.

117-0815-0029
WARNING!!!
DO NOT ATTEMPT TO USE THIS FACILITY TO GRIP BOWL BLANKS
WHICH HAVE NOT BEEN FULLY TURNED INSIDE AND OUTSIDE. THE
RE-CHUCKING FACILITY CANNOT BE USED AS A GRIPPING METHOD
TO DO MAJOR RE-SHAPING WORK OVER THE WHOLE OUTER
SURFACE OF THE BOWL. ALWAYS USE A CAUTIOUS AND
CONSERVATIVE APPROACH. USE CORRECT CHISEL TECHNIQUES
TO AVOID CHISEL DIG-INS WHICH COULD DISLODGE THE BOWL. DO
NOT USE HEAVY CUTS WHICH COULD ALSO DISLODGE BOWLS.
If you want to mount another accessory jaw set (e.g. 50mm, 75mm,100mm)
onto the Cole Jaws use the four longer M6x20mm screws provided. Note the
25mm jaws and pin jaws are not designed for use with Cole Jaws.
Only when both the inside and outside of the bowl have been turned (these
operation can all be performed with the Cole Jaws in conjunction with
another optional accessory jaw set) can the bowl be re-chucked to rework
the bottom (outside) surface. Bowls up to 240mm (9.45”) in diameter for
Cole Jaws, and bowls up to 171mm (6 ¾”) in diameter for Mini Cole Jaws,
can be re-chucked gripping the rim in the contracting mode. If re-chucking is
required to achieve a smooth under surface of the bowl, it is best to have
previously held the bowl by foot mounting (contracting mode) as it is much
easier turn off a foot rather than a recessed dovetail, for example. Foot
mounting method is best achieved with the Step Jaw or 100mm (Cole Jaws
only) Jaw Set.
C. Mounting Bowls
There are several radial positions available. The assembled rubber stoppers
need to be fastened so that they are screwed in flush against the jaw surface.
They need to be equally spaced at the same radial position on each segment
to achieve an even gripping of the bowl. The rubber stoppers will grip around
the rim of the bowl and contract downward. Refer to the directions in your
chuck manual for the contracting mode. Make sure the whole rim of the bowl
is seated flush against the jaw surface so that it is being well supported and
evenly gripped.

117-0815-00210
WARNING!!!
THE RUBBER STOPPERS ARE A CONVENIENT HOLDING METHOD BUT
MUST ONLY BE USED TO RE-CHUCK SMALL, LIGHTWEIGHT BOWLS
UP TO 250MM (10”) DIAMETER FOR COLE JAWS AND 200MM (8”) FOR
MINI COLE JAWS. NO RESPONSIBILITY CAN BE ACCEPTED FOR
USERS OWN ADAPTIONS OF THIS CUSTOM FACILITY, i.e., CUSTOM
WOODEN JAW SEGMENTS (MOUNTED ON COLE JAWS). IT IS THE
USERS RESPONSIBILITY TO TAKE ALL CARE TO ENSURE THAT A
SAFE MOUNTING OF BOWLS IS ACHIEVED.
If larger or heavy bowls need to be re-chucked, then you must make your
own wooden jaw segments. These should be fastened onto each jaw
segment using two screw positions. To ensure adequate gripping is achieved,
give careful consideration to the type of holding situation that is required
before false wooden jaws are made.
