hand (use the collet wrench 7 if necessary). Change
accessories 5 by inserting the new one into the collet 4
as far as possible to minimize runout and unbalance
(Fig. 13).
With the shaft lock engaged, finger tighten the collet
nut 3 in counterclockwise (T) direction until the acces-
sory shank 5 is gripped by the collet (Fig. 13). Avoid
excessive tightening of the collet nut when there is
no bit inserted.
To install a different collet, completely unscrew the col-
let nut 3 and remove the old collet 4. Insert the unslot-
ted end of the collet in the hole in the end of the tool
shaft 8. Replace collet nut on the shaft (Fig. 13).
Always use the collet, which matches the shank size
of the accessory you plan to use. Never force a larger
diameter shank into a collet.
- Fixing stuck collets
It is possible for a collet to get stuck within the collet nut
especially if a collet nut is tightened onto the tool without a
bit in place. If this happens, the collet 4 can be removed
from the collet 3 nut by pushing the shank of an accessory
6 into the hole in the collet nut. This should cause the col-
let to pop out of the collet nut (Fig. 14).

Introduction
Your Cordless Rotary Tool has a small, powerful elec -
tric motor, is comfort able in the hand, and is made to
accept a large variety of accessories including abra-
sive wheels, drill bits, wire brushes, polishers,
engraving cutters, and cutting wheels. Accessories
come in a variety of shapes and permit you to do a
num ber of different jobs. As you be come familiar with
the range of accessories and their uses, you will learn
just how versatile your Cordless Rotary Tool is. You'll
see dozens of uses you hadn't thought of before now.
The real secret of the Cordless Rotary Tool is its

- 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 col-
let a 1/4 turn. Re tighten collet nut and run the Cordless
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. To maintain balance on abrasive wheel
points, before each use, with the wheel point secured
in the collet, turn on the Cordless Rotary Tool and run
the 415 Dressing Stone (not included, available as
accessory) lightly against the revolving wheel point.
This removes high spots and trues up the wheel point
for good balance.
Remember, your new Dremel Cordless Rotary Tool is
the finest power tool of its kind. But its performance
is only as good as the accessories with which it is
used. We recommend only Dremel accessories be
used. Use of any other accessories may create a haz-
ard. We hope you'll enjoy many years of trouble free
pleasure from your Dremel Cordless Rotary Tool.
speed. To understand the advantages of its high
speed, you have to know that the standard portable
electric drill runs at speeds up to 2,800 revolutions
per minute. The typical electric drill is a low-speed,
high torque tool; the Cordless Rotary Tool is just the
opposite — a high-speed, low torque tool. The chief
difference to the user is that in the high speed tools,
the speed combined with the acces sory mounted in
the collet does the work. You don't apply pressure to
the tool, but simply hold and guide it. In the low speed
tools, you not only guide the tool, but also apply pres -
sure to it, as you do, for example, when drilling a hole.
It is this high speed, along with its compact size and
wide variety of special accessories, that makes your
Cordless Rotary Tool differ ent from other power
tools. The speed enables it to do jobs low speed tools
cannot do, such as en graving glass, etc.
