internal wires and components which
could cause serious hazard.
We
recommend that all tool service be performed

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
Bearings which become noisy (due to heavy
load or very abrasive material cut ting) should
be 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.
