NOTE:
When trying to remove an accessory, if the quick-
change collet begins to unthread from the tool, repeat the
install process.
DANGER:
If you are changing an accessory immediately after use,
be careful not to touch the collet or the accessory with
your hands or fingers. You will get burned because of
the heat build-up from operation. Always use the wrench
provided or allow the collet to cool.
USING MANDRELS
See Figure 5, page 15.
The most common types of mandrel to use with this tool
include the standard mandrel which is used with grinding

used with sanding drums.
To install:
Turn off the rotary tool.
Install the mandrel.
If using the standard mandrel:
Depress and hold the spindle lock button and rotate the
mandrel by hand until the spindle lock engages preventing
further rotation.
Insert the slot end of the provided wrench into the slot
on top of the mandrel and unscrew.

NOTE:
If necessary, tighten the screw on the drum
mandrel head to expand the drum and securely hold the
sanding drum in place.
BALANCING ACCESSORIES
For precision work, it is important that all accessories be
properly balanced. To balance an accessory, slightly loosen
the quick-change collet and give the accessory a 1/4 in. turn.
You should be able to tell by the sound and feel if the accessory
is running in balance. Continue adjusting in this fashion until
the best balance is achieved. Replace accessories if they
become damaged or unbalanced.
