&##+%,+ O To loosen, first press shaft
lock button and rotate the shaft by hand until
the lock engages the shaft preventing further
rotation. Your Dremel 8220 is equipped with a
quick collet lock mechanism. This mechanism
engages the output shaft in 8 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. G@:5 6I46DD:G6

The nose cap of your tool has an integrated

collet nut without the use of the standard collet
wrench. Unscrew the nose cap from the tool,
line-up steel insert on inside of cap with collet
nut. With the shaft lock engaged twist nose cap
clockwise to tighten, and counter-clockwise to
loosen.
