Service
Preventive maintenance
performed 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 Bosch Factory Service Center or Autho-
rized Bosch Service Station.
TOOL LUBRICATION
Your Bosch tool has been properly lubricated
and is ready to use. It is recommended that
tools with gears be regreased with a special
gear lubricant at every brush change.
CARBON BRUSHES
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 Bosch replacement brushes
specially 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 Bosch Factory Service
Center or Authorized Bosch Service Station.
Bearings which become noisy (due to heavy
load or very abrasive material cutting) should
be replaced at once to avoid overheating or
motor failure.
Cleaning
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
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
solvents damage plastic
parts.
Some of these are: gasoline, carbon
tetrachloride, chlorinated cleaning solvents,
ammonia and household detergents that
contain ammonia.

CAUTION
Accessories
If an extension cord is
necessary, 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.
NOTE:
The smaller the gauge number, the
heavier the cord.
