USING THE ROTARY
POWER 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. The Variable Speed tool has a
unique comfort
grip on the nose and back
seating, which allows the user added
comfort
and control
during use. You can feel
the difference!
When you turn on the tool for the first time,
hold it 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 may happen.
Practice on scrap materials
first to see how
the Rotary Tool cuts. 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 into the work.
Instead,
lower the spinning
accessory
lightly
to the work and allow it to touch the point at
which you want cutting
(or sanding
or
etching,
etc.) 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 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, for
example,
pass the tool back and forth over
the work, much as you would a small paint
brush. Cut 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 tess likely to make
errors, and will get the most efficient work
out of the accessory.
For best control in close work, grip the Rotary
Tool like a pencil between your thumb and
forefinger.
The "handgrip"
method
of holding the tool is
used for operations
such as grinding
a flat
surface or using cutoff wheels.
_
henever you hold the tool, be careful
not to cover the air vents with your hand.
This blocks the air flow and causes the motor to overheat.
