WARNING
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.
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 50 - 60 hours the brushes
be examined. Only genuine Dremel replacement brushes
specially designed for your tool should be used.
MAINTENANCE OF REPLACEABLE BRUSHES
ON MODEL F013039519
The brushes should be inspected frequently when tools
are used continuously. If your tool runs sporadically,
loses power, makes unusual noises or runs at a
reduced speed, check the brushes. To continue using
the tool in this condition will permanently damage your
tool.
With the cord unplugged, remove the brush caps one
at a time with a small screwdriver by rotating cap
counter-clockwise and check each brush.
CURVATURE OF HOUSING
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. 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.

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
commutator surface will "wear" longer.
BEARINGS
Model F013039519 has double ball bearing
construction. Under normal use they will not require
lubrication.
Cleaning

!
WARNING
connect the tool from the power
supply before cleaning or performing any main-
tenance. The tool may 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
by inserting pointed objects through openings.
Certain cleaning agents and

CAUTION
solvents damage plastic parts.
Some of these are: gasoline, carbon tetrachloride, chlo-
rinated cleaning solvents, ammonia and household
detergents that contain ammonia.
Extension Cords
If an extension cord is necessary,
!
WARNING
a cord with adequate size
conductors that is capable of carrying the current
necessary for your tool must be used. This will
prevent excessive voltage drop, loss of power or
overheating. Grounded tools must use 3-wire
extension cords that have 3-prong plugs and
receptacles.
