3.7. Replacing the brushes
Every 200 work hours, check the condition of the carbon brushes. To do this, unplug
the machine from the power source, and then
remove
the cap and the brush. If the
length of the brush is less than 10 mm (0.4
″), replace both brushes with new ones.
To install brushes, continue in reverse sequence. Then, let the motor operate
without load for 20 minutes.
