The "golf" grip method is used for heavier operations such
as grinding or cutting. PICTURE 7
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 8

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.
TO AVOID ACCIDENTS, ALWAYS
WARNING
!
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.
