Operating Procedure
WARNING:
Always be sure
the tool is in the Zero position
before changing accessories,
changing collets or servicing
your cordless rotary tool .
COLLET
—To loosen, first press shaft lock button and rotate the shaft by hand
until the lock engages the shaft preventing further rotation .
CAUTION
: Do not engage lock while the Rotary Tool is running .
With the shaft lock engaged use the collet wrench to loosen the collet nut if
necessary . Change accessories by inserting the new one into the collet as far as
possible to minimize run out and inbalance . 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 .
COLLETS
—Two different size collets (see illustration), to accommodate different
shank sizes, are available for your Cordless Rotary Tool .
COLLET IDENTIFICATION CHART
Collet sizes can be identified by the rings on the
back end of collet .
• 3/32” Collet has three (3)rings .
• 1/8” Collet has no rings .
To install a different 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 acces-
sory you plan to use . Never force a larger diameter
shank into a collet .
bALANCING ACCESSORIES
—For precision work, it is important that all acces-
sories 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 acces-
sory or collet a 1/4 turn . Retighten collet nut and run the 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, follow these instructions before each use: with the wheel
