MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Replacement of carbon brushes (Fig. 8 & 9)
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.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
