Replacing carbon brushes
Fig.11
When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically
shut off the motor. When this occurs, both carbon
brushes should be replaced. Keep the carbon brushes
clean and free to slip in the holders. Both carbon brushes
should be replaced at the same time. Use only identical
carbon brushes.
Remove the screws which secure the rear cover. Pry up
the rear cover with a screwdriver and remove it.

out the worn carbon brushes, insert the new ones and
secure the brush holder caps.
