3.6. Replacing the motor brushes
Every 100 work hours, check the condition of the brushes. To do this, unplug the
power cord and remove the cover (
1
). Lift the spring (
2
) and remove the brush. If the
brush is shorter than 5
mm (0.2″), replace the two brushes with new ones.
Install in reverse sequence. Then, let the motor operate with no load for
20 minutes.
