!WARNING performed by unauthorized personnel 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 Authorized Bosch Service Station.

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.
