MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and unplugged before attempting to perform inspection and maintenance.
Replacing carbon brushes
0 Both carbon brushes should be replaced after about 150 hours of use. When the resin insulating tip inside the carbon brush is exposed to contact the com- mutator, it will automatically shut off the motor. If carbon brushes wear out too quickly, ask Makita Authorized or Factory Service Centers to determine the cause before replacing them. Use only Makita carbon brushes.
