K. Collet
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.

on every 4000 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.

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
USE
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 10
The "golf" grip method is used for heavier operations such
as grinding or cutting. PICTURE 11
Nose Piece
For performing precision tasks a separate nose piece is
available. It has a trilobular shape which allows the user
to pinch the nose piece comfortably between thumb and
