Operating lnstructions
The Rotary Tool is a handful of high-speed power. lt ser-
ves as a carver, grinder, polisher, sander, cutter, power
brush, drill and more.
The Rotary Tool has a small, powerful electric universal
motor, is comfart able 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, cutting wheels and attachments. Accessories come
in a variety of shapes and permit you to do a number of
different jobs. As you be come familiar with the range of
accessories and their uses, you will learn just how versati-
le the Rotary Tool is. You'II see dozens of uses you hadn't
thought of befare.
The real secret of the Rotary Tool is its speed. To unders-
tand the advantages of its high speed, you have to know
that the standard portable electric drill runs at speeds up
to 8.000 revolutions per minute. The Rotary Tool operates
at speeds up to 33.000 revolutions per minute. The typical
electric drill is a lowspeed, high torque tool; the Rotary
Tool is just the opposite - a high-speed, low torque tool.
The majar 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 pressure to it,
as you do, far example, when drilling a hale.
lt is this high speed, along with its compact size and
wide variety of special accessories and attachments, that
makes the Rotary Tool differ ent from other tools. The
speed enables it to do jobs low speed tools cannot do,
such as cutting hardened steel, en graving glass, etc.
Getting the most out of your Rotary Tool is a matter of
learning how to let this speed work far you.
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 ar 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. This is not common, but it does
happen.
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 acces-
sory in the collet. You should not lean on ar push the tool
during use.
lnstead, lower the spinning accessory lightly to the work
and allow it to touch the point at which you want cutting (ar
sanding ar etching, etc.) 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.

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 make
a cut, far example, pass the tool back and farth over the
work, much as you would a small paint brush. Cut a little
material on each pass until you reach the desired depth.
Far 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
Far best control in clase work, grip the Rotary Tool like a
pencil between your thumb and farefinger.
Whenever you hold the tool, be careful not to cover the air
vents with your hand. This blocks the air flow and causes
the motor the motor to overheat.

Operating Speeds
To select the right speed for each job, use a practice
piece of material.
NOTE: Speed is affected by voltage changes. A redu-
ced incoming voltage will slow the RPM of the tool.
On the two-speed model, there is a LO and HI switch.
When the switch indicator is on the low setting, the tool
runs at about 8.000 RPM. When the switch indicator is on
the high setting, the tool runs at about 33.000 RPM.
The speed of Rotary Tool is controlled by setting this
indicator on the housing.
Needs for Slower Speeds
Certain materials, however, (sorne plastics and precious
metals, for ex ample) require a relatively slow speed be-
cause at high speed the friction of the accessory genera-
tes heat and may cause damage to the material.
