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.
