Motor Brushes

Periodically, the motor brushes need to be inspected for wear and damage (Figure 39).

Use a flat head screwdriver to remove the motor brush covers. Remove the brushes and inspect them. Brushes that are in usable condition will have no cracks or broken-off sections. There should only be a light grey build-up of carbon on the concave face of the brushes.

Replace the brushes if they are damaged or if they are coated with thick black carbon deposits.
