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 FEEDBACK
Your tool is equipped with an internal electronic feedback
system that provides a "soft start", which will reduce the
stresses that occur from a high torque start. The system
also helps to keep the preselected speed virtually constant
between no-load and load conditions.
VARIABLE SPEED DIAL
Your tool is equipped with a variable speed dial. The
speed may be adjusted during operation by presetting the
dial on or between any one of the settings.
The speed of Rotary Tool is controlled by setting this dial
on the housing. PICTURE 13
Settings for Approximate Revolutions
Switch Setting Speed Range
5 5,000 RPM
10 10,000 RPM
*15 15,000 RPM
20 20,000 RPM
25 25,000 RPM
30 30,000 RPM
35 35,000 RPM
* Do not exceed 15,000 RPM 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 (15,000 RPM 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 15,000 RPM 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.
MAINTENANCE
Preventive maintenance performed by unauthorized
personnel may result in misplacing of internal wiring
and components which could cause serious hazard. We
