Collet Nut
•
To loosen (1) the collet nut (a), first press the shaft lock button (b) 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 (c) 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 run out and unbalance.
•
With the shaft lock engaged, finger-tighten the collet nut until the accessory shank
is gripped by the collet.
Using the wrench, completely tighten (2) to fully secure the accessory.
NOTE: Avoid excessive tightening of the collet nut when there is no bit inserted.

4.

5.
Tighten the collet nut by turning it finger-tight in a clockwise direction until the
accessory is firmly clamped. Completely tighten using the wrench.
