MAKING CUT-OUTS IN MATERIALS
OTHER THAN DRYWALL
Your tool is capable of cutting many types of
building materials in addition to drywall.
There are several different bits available for
use on these materials. Most materials can
be cut with the "multipurpose" bit, however
the "carbide" burr bits must be used for hard,
abrasive materials such as ceramic wall tile
(will not work on ceramic floor grade tile),
cement board, plaster etc.
To make cut-outs, insert and adjust the
proper bit according to previous instructions.
Hold the tool firmly and turn it on. Place the
depth guide at about a 45º angle against the
work surface and tilt the tool to an upright
position with the bit entering the scrap portion
of the area being cut. Move the bit to the line
you wish to follow and cut in a clockwise
direction. Cutting at a slow even rate will
make following a line easier and will put less
stress on the bit.
NOTE: When cutting on a vertical surface,
avoid ending your cut at the bottom of the
hole. If possible, start and end your cut at the
top so the scrap part will not drop onto the
rotating bit. Turn the tool off and remove it
from the cut out hole.

Maintenance Information

CLEANING
To avoid accidents always
WARNING
!
disconnect the tool from the
power supply before cleaning or performing
any maintenance. 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, chlorinated cleaning solvents,
ammonia and household detergents that contain
ammonia.

WARNING
!
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.
The brushes and commutator in your tool have
been engineered for many hours of dependable
service. To maintain peak efficiency of the
motor, we recommend every two to six months
the brushes be examined. Only genuine Dremel
replacement brushes specially designed for
your tool should be used.
MAINTENANCE OF REPLACEABLE
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.
If the brush is less than 1/4" 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 simultaneously. If one
brush is worn out, replace both brushes. Make
sure the brushes are installed as illustrated. The
curved surface of the brush must match the
curvature of the commutator.

CAP
After replacing brushes the tool should be run at
no-load; place it on a clean surface and run it
freely 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 9000 is equipped with ball
bearing construction. Under normal use no
additional lubrication is required.
