ASSEMBLY AND ADJUSTMENT
WARNINg:
Always be sure that the tool is switched off before adjusting,
adding accessories, or checking a function on the tool
.
COLLETS
your rotary tool comes from the factory set-up to use 1/8" shank accessories like those included
with your kit. The accessory shank is held in place via a special split collet in the motor shaft and the
external collet nut.
your rotary tool can use different sizes of collets 3/32"
1/16" or 1/32" (not included) to accommodate different
shank sizes.
Always use the collet which
matches the accessory shaft size. Never
force a larger diameter shaft into a collet
.
To install a different collet
, remove the collet
nut and pull the old collet out. Insert the new collet
in. Replace the collet nut on the shaft. (See fIG 2)
INSTALLING AND REMOVING ACCESSORIES
1. Switch off the tool (See Switch Action Instructions).
2. Depress the shaft lock button (2-fIG 1) firmly and rotate the shaft by hand until the lock engages,
preventing further rotation of the shaft.
3. With the shaft lock engaged, loosen the collet nut by rotating it in a counterclockwise direction.
4. Do not remove the collet nut from the threaded motor shaft, only loosen the collet nut enough to
remove or add an accessory.
5. Insert the accessory shank through the collect nut as far as it will go, this will help to minimize
accessory bit running out of balance.
6. With the shaft lock engaged, hand tighten the collet nut by rotating it in a clockwise direction until
the shank is held securely in the collet.
Do not over tighten or use any tools to tighten
.
WARNINg:
DO NOT engage the shaft lock while the tool is running
WARNINg:
Avoid excessive tightening of the collet nut. Do not over-
tighten the collet nut when no bit is inserted.
BALANCING
for best results, be sure to balance each accessory in the collet. The high RPM of the tool makes an
imbalanced accessory very detectable as a wobble will occur while the tool is running.
To balance an accessory:
1. Stop the tool.
2. Loosen the collet nut.
3. Rotate the accessory 1/4 turn.
4. Tighten the collet.
5. Run the tool.
Continue adjusting as needed. you will hear and feel when the accessory is properly balanced.
