Dremel 200 series Original Instructions Manual page 23

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.
For best control in close work, grip the multitool like a
pencil between your thumb and forefinger. PICTURE 7
The "golf" grip method is used for heavier operations such
as grinding or cutting. PICTURE 8
OPERATING SPEEDS
To select the right speed for each job, use a practice piece
of material.
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.
ON/OFF SWITCH AND SPEED DIAL
Your tool is equipped with a high and low speed dial. The
speed may be adjusted during operation by presetting the
dial on one of the two settings.
The speed of Rotary Tool is controlled by setting this dial
on the housing. PICTURE 2
Settings for Approximate Revolutions

High 35000 min
* Do not exceed 15000 min 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
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
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
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 turn off powertool 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 9
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 10
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.
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.
