To loosen the collet nut, first press shaft lock
button and rotate the shaft by hand until the
lock engages the shaft preventing further
rotation. Your Dremel Micro is equipped with
a shaft lock mechanism. This mechanism
engages the output shaft in 2 separate
locations on the shaft for easier operation.

With the shaft lock engaged, use the collet
wrench to loosen the collet nut if necessary.
The collet nut must be loosely threaded on
when inserting an accessory. 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.

Four different size collets (see illus tration), to
accommodate different shank sizes, are
avail able for your Rotary Tool. 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.

Never force a larger diameter shank into a

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 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, with the wheel point
secured in the collet, turn on the Rotary Tool
and run the 415 Dressing Stone lightly
against the revolving wheel point. This
removes high spots and trues up the wheel
point for good balance.
