MAINTENANCE CAUTION:
•Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.

Replacing carbon brushes

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.
Use a hex wrench to remove the motor housing cover.
Use a screwdriver to remove the brush holder caps. Take out
the worn carbon brushes, insert the new ones and secure
the brush holder caps.
