COLLETS
The Dremel accessories available for the multitool come
with various shank sizes. Four size collets are available to
accommodate the different shank sizes. Collet sizes are
identified by the rings on the back of the collet.

Always use the collet that matches the shank size of the
accessory you plan to use. Do not force a larger diameter
shank into a smaller collet.

4. Install the appropriate size collet fully into the shaft and
reinstall the collet nut finger tight. Do not fully tighten
the nut when there is no bit or accessory installed.
CHANGING ACCESSORIES

not remove) the collet nut. Use the collet wrench if
necessary.
3. Insert the bit or accessory shank fully into the collet.
4. With the shaft lock button engaged, finger tighten the
collet nut until the bit or accessory shank is gripped by
the collet.

Dremel accessory for further information on its use.
Use only Dremel tested, high performance accessories.
EZ TWIST™ INTEGRATED WRENCH/NOSE CAP
PICTURE 4
F. EZ Twist™ integrated wrench/nose cap (not available
on every 8200 tool)
This nose cap has an integrated wrench allowing you to
loosen and tighten the collet nut without the use of the
standard collet wrench.
1. Unscrew the nose cap from the tool, line-up the steel
insert on inside of the cap with the collet nut.
2. With the shaft lock engaged twist nose cap counter
clockwise to loosen the collet nut. Do not engage the
shaft lock button while multitool is running.
3. Insert the bit or accessory shank fully into the collet.
4. With the shaft lock engaged twist nose cap clockwise
to tighten the collet nut.
5. Screw the nose cap back into its original position.
NOTE: Be sure to read the instructions supplied with
your Dremel accessory for further information on its
use.
Use only Dremel tested, high performance accessories.
BALANCING ACCESSORIES
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.
GETTING STARTED
The first step in using the multitool is to get the "feel" of it.
Hold it in your hand and feel its weight and balance. Feel
the taper of the housing. This taper permits the tool to be
grasped much like a pen or pencil.
Always hold the tool away from your face. Accessories
can be damaged during handling and can fly apart as
they come up to speed.
When holding tool, do not cover the ventilation
openings with your hand. Blocking the ventilation
openings could cause the motor to overheat.
IMPORTANT! Practice on scrap material first to see how
the tool's high-speed action performs. Keep in mind that
your multitool will perform best by allowing the speed,
along with the correct Dremel accessory and attachment,
to do the work for you. Do not put pressure on the
tool during use, if possible. Instead, lower the spinning
accessory lightly to the work surface and allow it to touch
the point at which you want to begin. Concentrate on
guiding the tool over the work using very little pressure
from your hand. Allow the accessory to do the work.
Usually it is better to make a series of passes with the tool
rather than to do the entire job with one pass. A gentle
touch gives the best control and reduces the chance of
error.
HOLDING THE TOOL
For best control in close work, grip the multitool like a
pencil between your thumb and forefinger. PICTURE 6
