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 AND CLEANING
NO USER SERVICEABLE PARTS INSIDE (you can
!
only inspect and replace the carbon brushes
(3000/4250/4300)). PREVENTIVE MAINTENANCE
PERFORMED BY UNAUTHORIZED PERSONNEL MAY
RESULT IN INCORRECT CONNECTION OF INTERNAL
WIRING AND COMPONENTS WHICH COULD CAUSE
SERIOUS HAZARD.
INSPECTING/REPLACING CARBON BRUSHES
(3000/4250/4300)
A f
Inspect the brushes for wear every 40-50 hours of use.
Also inspect the brushes when the tool runs erratically,
loses power, or makes unusual noises.
Using the tool with worn brushes will permanently
damage the motor.
Use only original DREMEL replacement brushes.
1. Unplug the tool and place it on a clean surface.
2. Remove the two brush caps with the tool wrench as a
screwdriver.
3. Remove the two brushes from the tool by pulling the
springs that are attached.
4. Inspect both brushes. If a brush is less than 3mm
long and/or the surface of the brush is rough or pitted,
replace the carbon brush by a new one:
– remove the spring from the brush
– throw away the old brush and place the spring on
a new brush
5. Place the carbon brushes (with spring) back into the
tool (there is only one way the brush will fit back into
the tool).
6. Replace the brush caps by turning the caps clockwise
(to tighten, use the wrench - do not overtighten).
NOTE: If one brush is worn, you should replace both
brushes for better performance of the tool.
The tool can be cleaned most effectively with compressed
dry air. Always wear safety goggles when cleaning
tools with compressed air.
TO AVOID ACCIDENTS, ALWAYS DISCONNECT THE
!
TOOL AND/OR CHARGER FROM THE POWER
SUPPLY BEFORE CLEANING
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.
CERTAIN CLEANING AGENTS AND SOLVENTS
!
DAMAGE PLASTIC PARTS. Some of these are:
gasoline, carbon tetrachloride, chlorinated cleaning solvents,
ammonia and household detergents that contain ammonia.

NOTE: The declared vibration total value has been
measured in accordance with a standard test method and
may be used for comparing one tool with another. It may
also be used in a preliminary assessment of exposure.
THE VIBRATION EMISSION DURING ACTUAL USE
OF THE POWER TOOL CAN DIFFER FROM THE
DECLARED TOTAL VALUE DEPENDING ON THE WAYS
IN WHICH YOU USE THE TOOL. Make an estimation of
the exposure in the actual conditions of use and identify
the safety measures for personal protection accordingly
(taking account of all parts of the operating cycle such
as the times when the tool is switched off and when it is
running idle in addition to the trigger time).
DISPOSAL
The tool, accessories and packaging should be sorted for
environmental-friendly recycling.
