The task of the carbon brushes is to transport the power to the armature via the rotating collector. There
are two carbon brushes. They should be checked regularly and changed in pairs after approx. 100 hours
normal operating time.
N.B.
Carbon brushes wear more quickly when subjected to high loads.
Exchange:
Unplug the machine. Remove the plastic covers from the machine front cover. Unscrew the two black coal
covers on the machine housing. Pull out the carbon brushes. Check that the carbon brushes slides easily
from their position. If necessary replace them. When reassembling, check that the springs are correctly
placed in their positions.
N.B.
Don’t over tighten the carbon brush covers! Start the machine for testing.
