CARBON BRUSHES
The brushes and commutator in your tool have
been engineered for many hours of
dependable service.
In order to prepare your brushes for use, run
your tool at full speed for 5 minutes under no
load. This will properly "seat" your brushes,
which extends the life of both your brushes
and your tool.
To maintain peak efficiency of the motor, we
recommend every 40 - 50 hours the brush es
be examined. Only genuine Dremel replace -
ment brushes specially designed for your tool
should be used.
MAINTENANCE OF REPLACEABLE
BRUSHES ON MODELS 100, 200 & 3000
The brushes should be inspected frequently
when tools are used continuously. If your tool
runs spo rad ically, loses power, makes unusual
noises or runs at a reduced speed, check the
brushes.

Maintenance Information

CAUTION
!
permanently damage your tool.
Follow these steps to check/change the rotary
tool brushes:
1. With the power cord unplugged, place the
tool on a clean surface. Use the tool
wrench as a screwdriver to remove the
injury
from
brush caps in a counter-clockwise direction
(Figure C).
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 1/8"
long and the end surface of the brush that
contacts the commutator is rough and/or
pitted, they should be replaced. Check both
brushes (Figure D).
Usually the brushes will not wear out simul -
taneously. If one brush is worn out, replace
both brushes. Make sure the brushes are
installed as illus trated. The curved surface
of the brush must match the curvature of
the commutator.
3. After replacing 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 total life of
your tool since the com mutator surface will
"wear" longer.
