Stall Protection

This tool has a stall protection feature built
into it to protect the motor in the event of a
stall. If you stall the tool for too long, or bind
the bit in a work piece, especially at high
speeds, it will automatically turn itself off.
Simply take the tool out of the material you
were stalled in, turn it back on again to
continue using it.

Using the Rotary Tool

The first step in learning to use the Rotary Tool
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 Rotary Tool
to be grasped much like a pen or pencil (Fig. 4).

cover the air vents with your hand. This
blocks the air flow and causes the motor to

Practice on scrap materials first to see how the
Rotary Tool's high speed action performs. Keep
in mind that the work is done by the speed of
the tool and by the accessory in the collet. You
should not lean on or push the tool during use.
Instead, lower the spinning accessory lightly to
the work and allow it to touch the point at which
you want sanding or etching to begin. Con -
centrate on guiding the tool over the work using
very little pressure from your hand. Allow the
accessory to do the work.
For best control in close or detailed work, grip
the Rotary Tool like a pencil between your
thumb and forefinger (Fig. 4).
The "Golf Grip" method of holding the tool is
used for more aggressive operations such as
sanding or grinding a flat surface (Fig. 5).
Usually, it is best to make a series of passes with
the tool rather than attempt to do all the work in
one pass. To sand a wooden surface, for
example, pass the tool back and forth over the
work, much as you would a small paint brush.
Sand a little material on each pass until you
reach the desired depth. For most work, the
gentle touch is best. With it, you have the best
control, are less likely to make errors, and will
get the most effi cient work out of the accessory.
To select the right speed for each job, use a
practice piece of material.

VARIABLE SPEED DIAL

Your tool is equipped with a variable speed
dial. The speed may be adjusted during
operation by presetting the dial on or
between any one of the settings.
