GETTING STARTED
The first step in using the multitool 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 tool to be grasped much like
a pen or 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.
When holding tool, do not cover the ventilation openings with your
hand. Blocking the ventilation openings could cause the motor to
overheat.
IMPORTANT! Practice on scrap material first to see how the tool's
high-speed action performs. Keep in mind that your multitool will
perform best by allowing the speed, along with the correct Dremel
accessory and attachment, to do the work for you. Do not put
pressure on the tool during use, if possible. Instead, lower the
spinning accessory lightly to the work surface and allow it to touch
the point at which you want 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 better to make a series of passes with the tool rather
than to do the entire job with one pass. A gentle touch gives the
best control and reduces the chance of error.
HOLDING THE TOOL
For best control in close work, grip the multitool like a pencil
between your thumb and forefinger. PICTURE 7
The "golf" grip method is used for heavier operations such as
grinding or cutting. PICTURE 8

A. On/Off / Variable speed slide switch
To select the right speed for each job, use a practice piece of
material.
SLIDE "ON/OFF" and speed setting SWITCH
The tool is switched "ON" by the slide switch located on the
top side 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 Dremel attachments.
ELECTRONIC MONITORING
Your tool is equipped with an internal electronic monitoring system
that provides a "soft start", which will reduce the stresses that
occur from a high torque start. The system also helps to maximize
motor and battery performance by cutting the voltage to the tool
when stall conditions (see section "Stall Protection") occur. The
USE
motor and battery pack are protected by cutting back the voltage
to the motor in these situations.
VARIABLE SPEED SLIDE SWITCH
Your tool is equipped with a variable speed slide switch. The
speed may be adjusted during operation by sliding the switch
back or forth between any one of the settings.
The speed of Rotary Tool is controlled by setting this dial on the
housing.

Refer to the Speed Settings chart on pages 12-15 to help
determine the proper speed for the material being worked on and
the accessory to use.
Most jobs can be accomplished using the tool at the highest
setting. However, certain materials (some plastics and metals)
can be damaged by high-speed generated heat and should
be worked on at relatively low speeds. Low speed operation
(15000 min or less) is usually best for polishing operations
–1
employing the felt polishing accessories. All brushing applications
require lower speeds to avoid wire discharge from the holder. Let
the performance of the tool do the work for you when using lower
speed settings. Higher speeds are better for hardwoods, metals
and glass and for drilling, carving, cutting, routing and shaping.
Some guidelines regarding tool speed:
•
Plastic and other materials that melt at low temperatures
should be cut at low speeds.
•
Polishing, buffing and cleaning with a wire brush must be
done at speeds no greater than 15000 min
damage to the brush and your material.
•
Wood should be cut at high speed.
•
Iron or steel should be cut at high speed.
•
If a high speed steel cutter starts to vibrate, it usually
indicates that it is running too slowly.
•
Aluminium, copper alloys, lead alloys, zinc alloys and tin may
be cut at various speeds, depending on the type of cutting
being done. Use a paraffin (not water) or other suitable
lubricant on the cutter to prevent the cut material from
adhering to the cutter teeth.
NOTE: Increasing pressure on the tool is not the answer when
it is not performing properly. Try a different accessory or speed
setting to achieve the desired result.
STALL PROTECTION
This tool has a stall protection feature built into it to protect the
motor and battery in the event of a stall. If you put too much
