2. While continuing to hold the shaft
locking button IN, use the collet
wrench (3) to turn the collet nut
counter-clockwise. Loosen the collet

3. Remove the bit if one is already
installed in the tool.

way into the collet and then pull it back
between 1/16" and 1/8". This creates an
air space between the motor shaft and
the bit to help protect the bit from
overheating.
Before tightening the collet on the bit,
make sure the flutes (spiral portion) of
the bit are completely visible outside
the collet. Clamping the collet on the bit
flutes will result in broken bits and
possible injury.

collet, depress the shaft locking button
