cover the air vents with your hand. This
blocks the air flow and causes the motor to
overheat.
For best control in close work, grip the Rotary
Tool like a pencil between your thumb and
forefinger (Figure A).

To select the right speed for each job, use a
practice piece of material.
SLIDE "ON/OFF" SWITCH
The tool is switched "ON" by the slide switch
located on the topside of the motor housing.
TO TURN THE TOOL "ON", slide the switch
button forward.
TO TURN THE TOOL "OFF", slide the switch
button backward.
HIGH PERFORMANCE MOTOR
Your tool is equipped with a high performance
rotary tool motor. This motor expands the
versatility of the rotary tool by driving additional
attachments such as the Dremel Multi-Saw
and Dremel Planer.
ELECTRONIC MONITORING
Your tool is equipped with an internal electronic
monitoring system that provides a "soft start",
Whenever you hold the
tool, be careful not to
Operating Speeds
The "Golf Grip" method of holding the tool can
be used for more aggressive operations such
as grinding a flat surface or using cutoff
wheels (Figure B).
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 cutting (or sanding or 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, 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 less likely to make errors, and will
get the most effi cient work out of the
accessory.

which will reduce the stresses that occur from
a high torque start. The system also helps to
maximize motor and battery performance by
by limiting the current to the tool when overload
and stall conditions occur. The motor and
battery pack are protected by limiting the
current to the motor in these situations.
VARIABLE SPEED ADJUSTER
Your tool is equipped with a variable speed
adjuster. The speed may be adjusted during
operation by sliding the adjuster back or forth
between any one of the settings.
You can refer to the charts on pages 27 – 30
to determine the proper speed, based on the
materi al being worked and the type of
accessory being used. These charts enable
you to select both the correct acces sory and
the optimum speed at a glance.
