Maintenance and Service
WARNING!
Preventive maintenance per-
formed by unauthorized personnel may result
in misplacing of internal wires and components
which could cause serious hazard. We recom-
mend that all tool service be performed at a
Bosch Factory Service Center.
Tool Lubrication
Your Bosch tool has been properly lubricated
and is ready for use. We recommend, that tools
with gears be regreased with a special gear
lubricant every time the brushes are changed.
Carbon Brushes
The brushes and commutator in your Bosch
tool have been engineered for many hours of
dependable service. To maintain peak effi-
ciency of the motor, we recommend that every
two to six months the brushes be examined.
Only genuine Bosch replacement brushes spe-
cially designed for your tool should be used.
Bearings
After about 300-400 hours of operation, or at
every second brush change, the bearings should
be replaced at a Bosch Factory Service Center.
Bearings which become noisy (due to heavy
load or very abrasive material cutting) should
be replaced at once to avoid overheating and
motor failure.
Cleaning
WARNING!
To avoid accidents, always
disconnect the tool from the power supply
before cleaning or performing any maintenance.
The tool may be cleaned most effectively with
compressed 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.
CAUTION!
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.
Deluxe Router Guide
For routing operations such as grooving or
dadoing, it is often necessary to guide the tool
in a line parallel to a straight edge. One method
of obtaining a straight cut is to securely clamp
a board or other straightedge to the work sur-
face, and guide the edge of the router sub-base
along this path. It is best to keep the router in one
position as it is moved along the guide, as this
will produce the straightest cut.
The Bosch deluxe router guide is an accessory
that will guide the router parallel to a straight
edge or around a curved surface. The deluxe
router guide is supplied with two rods and a
series of wing nuts and screws to fasten the
guide and adjust its position relative to the bit.
With the guide installed and adjusted, the router
should be fed normally, keeping the guide in
contact with the edge of the workpiece at all
times. The deluxe router guide may also be
positioned under the router base for operations
where a limited amount of bit exposure is de-
sired.
The Bosch deluxe router guide includes a
fine-adjustment mechanism for extra precision,
and removable face plates for guiding the router
along straight or curved surfaces. For proper
operation, please refer to the instructions which
are included with this accessory.
Chip Extraction
Your BOSCH plunge router may be fitted with
a chip extraction attachment to help keep your
work environment cleaner. This attachment
can be used for general routing, and has an
adjustable brush attachment that is especially
well-suited to grooving applications. Please
see your BOSCH Power Tool distributor for
more details about these and other optional
accessories.
WARNING!
Use of any accessory not speci-
fied in this manual or the BOSCH catalog for
use with this tool may create a hazard.
