Rotary Tool is running.
With the shaft lock engaged use the collet wrench to
loosen the collet nut if necessary. Change accessories
by inserting the new one into the collet as far as possi-
ble to minimize runout and unbalance. With the shaft
lock engaged, finger tighten the collet nut until the
accessory shank is gripped by the collet. Avoid exces-
sive tightening of the collet nut.
COLLETS — Four different size collets (see illus-
tration), to accommodate different shank sizes, are
available for your Cordless Rotary Tool. To install a dif-
ferent collet, remove the collet nut and remove the old
collet. Insert the unslotted end of the collet in the hole
Introduction
The Cordless Rotary Tool is a handful of high-speed
power. It serves as a carver, a grinder, polisher, sander,
cutter, power brush, drill and more.
Your Cordless Rotary Tool has a small, powerful electric
motor, is comfortable in the hand, and is made to accept
a large variety of accessories including abrasive wheels,
drill bits, wire brushes, polishers, engraving cutters,
router bits, and cutting wheels. Accessories come in a
variety of shapes and permit you to do a number of
different jobs. As you become 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.

in the end of the tool shaft. Replace collet nut on the
shaft. 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.
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 Tool. You should be able
to tell by the sound and feel if your accessory is run-
ning in balance. Continue adjusting in this fashion until
best balance is achieved. To maintain balance on abra-
sive 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 lightly against the
revolving wheel point. This removes high spots and
trues up the wheel point for good balance.
Operation Instructions
The real secret of the Cordless Rotary Tool is its 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 accessory 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 pressure to it, as you do, for example,
when drilling a hole.
