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 only at switch setting 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 slow.
• 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
Preventative maintenance performed by unauthorized personnel
may result in misplacing of internal wires 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.
carBOn BrusHEs
The brushes in your tool have been engineered for many hours
of dependable service. To prepare the brushes for use, run the
tool at full speed for 5 minutes under no load. This will properly
"seat" the brushes, and extend the life of the tool. To maintain
peak efficiency of the motor, examine the brushes for wear every
40-50 hours.
Using the tool with worn brushes will permanently damage the
motor. Use only original Dremel replacement brushes.' Inspect
the multitool brushes after 40-50 hours of use. If the multitool
runs erratically, loses power, or makes unusual noises check the
brushes for wear and possible replacement. Follow these steps to
check/change the multitool brushes:
1. With the power cord unplugged, place the tool on a clean
surface. Use the tool wrench as a screwdriver to remove the
brush caps. PICTURE 8
2. Remove the brushes from the tool by pulling on the spring
that is attached to the carbon brush. If the brush is less than
3mm long and the surface of the brush that touches the

commutator is rough or pitted, the carbon brushes should be
replaced. Be sure to check both brushes. PICTURE 9
3. If one brush is worn, you should replace both brushes for
better performance of your multitool. Remove the spring from
the brush, throw away the old brush and place the spring on
a new brush.
4. Place the carbon brush and spring back into the tool, there is
only one way the brush will fit back into the tool.
5. Replace the brush caps onto the tool by turning the cap in a
clockwise direction. To tighten, use the wrench, but DO NOT
OVER TIGHTEN! After replacing the brushes the tool should
be run at no load; place it on a clean surface and run it freely
at full speed for 5 minutes before loading (or using) the tool.
This will allow the brushes to "seat" properly and will give you
more hours of life from each set of brushes. This will also
extend the life of your tool since the commutator surface will
also wear better and longer.

Ventilation openings and switch levers must be kept clean and
free of foreign matter. Do not attempt to clean by inserting pointed
objects through openings.
The tool may be cleaned with compressed air. Always wear safety
goggles when cleaning tool with compressed air.
There is no need to lubricate the Dremel multitool.
Certain cleaning agents and solvents will damage plastic parts.
Some of these are: gasoline, carbon tetrachloride, chlorinated
cleaning solvents, ammonia and household detergents that
contain ammonia.
Clean the "soft grip" areas of the tool using a damp cloth. Tougher
soiled areas may require more than one wipe application to get
clean.
