COLLET NUT— To loosen, first press shaft lock button
and rotate the collet nut by hand until the lock engages
the shaft preventing further rotation.
With the shaft lock engaged, loosen the collet nut by
hand. Change accessories by inserting the new one
into the collet as far as possible to minimize runout and
unbalance. With the shaft lock engaged, finger tighten
the collet nut until the accessory shank is gripped by
the collet. Avoid excessive tightening of the collet
nut when there is no bit inserted.
COLLETS — Four different size collets (see illus -
tration), to accommodate different shank sizes, are
avail able for your Cordless Rotary Tool. To install a dif-
ferent collet, remove the collet nut and remove the old
collet. Insert the unslotted end of the collet in the hole
in the end of the tool shaft. Replace collet nut on the
shaft. Always use the collet which matches the shank
size of the accessory you plan to use. Never force a
larger diameter shank into a collet.

FIXING STUCK COLLETS – It is possible for a collet to get
stuck within the collet nut especially if a collet nut is tight-
ened onto the tool without a bit in place. If this happens,
the collet can be removed from the collet nut by pushing
the shank of an accessory into the hole in the collet nut.
This should cause the collet to pop out of the collet nut.
BALANCING ACCESSORIES — For precision work, it is
important that all accessories be in good balance
(much the same as the tires on your automobile). To
true up or balance an accessory, slightly loosen collet
nut and give the accessory or collet a 1/4 turn. Re -
tighten collet nut and run the Cordless Rotary Tool. You
should be able to tell by the sound and feel if your
accessory is running in balance. Continue adjusting in
this fashion until best balance is achieved. To maintain
balance on abrasive wheel points, before each use,
