ON:
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 at the same time.
Use only identical carbon brushes.
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.
