3.8. Replacing the brushes
Check the condition of the carbon brushes every 200 operation hours. To do this,
unplug the machine from the power source, unscrew the cap, and remove the brush
(Fig. 10). If the length of the brush is less than 10 mm (0.4’’), replace both brushes
with new ones. To install brushes, proceed in reverse order. After the replacement, run
the motor without load for 20 minutes.
