Carbon brush replacement
Service
• Carbon brushes should be checked periodically.
• When one or both carbon brushes show signs of wear go
to a Authorized Service center to have
both carbon brushes replaced. When replaced, see if the
new carbon brushes move freely in the carbon brush
housing. Ask to turn on the tool during five minutes to
make the contact in the carbon brushes and the commuter
even.
• Use only original spare carbon
brushes, designed specifically with the right strength and
electric resistance for each type of motor. Carbon brushes
with different specifications may damage the motor.
• When replacing carbon brushes, always change both.
