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.

!<A<??B@5%2=9.02:2;A

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.
