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
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

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.

remove the saw blade from the tool and lightly

necessary, a cord with
