2. With the shaft lock engaged twist nose cap counter
clockwise to loosen the collet nut. Do not engage the shaft
lock button while multitool is running.
3. Insert the bit or accessory shank fully into the collet.
4. With the shaft lock engaged twist nose cap clockwise to
tighten the collet nut.
5. Screw the nose cap back into its original position.
NOTE: Be sure to read the instructions supplied with your
Dremel accessory for further information on its use.
Use only Dremel tested, high performance accessories.
BALANCING ACCESSORIES
For precision work, it is important that all accessories be in good
balance (much the same as the tires on your automobile). To
true up or balance an accessory, slightly loosen collet nut and
give the accessory or collet a 1/4 turn. Re tighten collet nut and
run the Rotary Tool. You should be able to tell by the sound and
feel if your accessory is running in balance. Continue adjusting
in this fashion until best balance is achieved.
USE
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 5
The "golf" grip method is used for heavier operations such as
grinding or cutting. PICTURE 6
OPERATING SPEEDS
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
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 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. PICTURE 7

when using wire brushes.
Refer to the Speed Settings chart on pages 4-7 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
–1 or less) is usually best for polishing operations
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
–1
to prevent
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
pressure on the tool for too long, or bind the bit in a work piece,
especially at high speeds, the motor will stop. Simply take the
tool out of the material you were stalled in, and the tool will
begin to spin again at the selected speed. If the tool continues
to stall for longer than 5 seconds, the tool will automatically shut
itself off. This additional feature further protects the motor and
the battery from damage. When the battery becomes close to
empty, the tool may shut down automatically more frequent than
normal. If this happens, it is time to recharge the battery.
MAINTENANCE
Preventive maintenance performed by unauthorized personnel
may result in misplacing of internal wiring and components
which could cause serious hazard. We recommend that all tool
service be performed by a Dremel Service Facility. To avoid
injury from unexpected starting or electrical shock, always
remove plug from wall outlet before performing service or
cleaning.
CLEANING
!
WARNING
TO AVOID ACCIDENTS, ALWAYS
DISCONNECT THE TOOL AND/OR CHARGER
FROM THE POWER SUPPLY BEFORE CLEANING. The tool
can be cleaned most effectively with compressed dry air.
Always wear safety goggles when cleaning tools with
compressed air.
Ventilation openings and switch levers must be kept clean
and free of foreign matter. Do not attempt to clean the tool by
inserting pointed objects through an opening.

WARNING
CERTAIN CLEANING AGENTS AND
SOLVENTS DAMAGE PLASTIC PARTS.
Some of these are: gasoline, carbon tetrachloride,
