Preventive maintenance

per so n nel 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

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 brush es be examined. Only genuine Bosch
replace ment 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 Au thorized Bosch Service Station.
Bearings which become noisy (due to heavy
load or very abrasive material cut ting) should
b
e replaced at once to avoid overheating or
motor failure.
Cleaning
To avoid accidents always dis 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 gog gles when
cleaning tools with compressed air.
Ventilation openings and switch levers must be
kept clean and free of foreign matter. Do not
at tempt to clean by inserting pointed objects
through openings.
Certain cleaning agents
and sol vents damage
plastic parts. Some of these are: gasoline,
carbon tetrachlo ride, chlo rinated cleaning
solvents, ammonia and house hold detergents
that contain ammonia.
