Service
All tool service should be
performed by a Bosch
F
actory Service Center or an Authorized Bosch
Service Station. Preventive maintenance
performed by unauthorized personnel may result
in misplacing of internal wires and components
which could cause serious hazard.
Motor 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 2-6 months the brushes be
examined. Only genuine Bosch replacement
brushes specially designed for your tool should be
used.
MOTOR BRUSH REPLACEMENT
To inspect or replace brushes:
1. Unplug the saw.
2. Loosen motor endcap screws, and remove motor
endcap.
3. Remove brush from brush holder by pulling back
tension spring, then pull the brush out using the
conecting wire, then unplug the terminal wire,
figure 54.
NOTE: If installing the existing brush or brushes,
make sure the brush goes in the same way it came
out. Otherwise, a break-in period will occur that
will reduce motor performance and increase brush
wear.
4. To reinstall new brushes follow steps in reverse.
