MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
Replacing carbon brushes
Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only iden-
tical 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.
NOTE:
• When replacing carbon brush located on the same side
as the knob, remove the knob first before unscrewing the
brush holder cap.
CAUTION:
• Be sure to re-install the knob after inserting new carbon
brush.
After replacing brushes, plug in the tool and break in brushes
by running tool with no load for about 10 minutes. Then
check the tool while running and electric brake operation
when releasing the switch trigger. If electric brake is not
working well, ask your local Makita service center for repair.
To maintain product SAFETY and RELIABILITY, repairs, any
other maintenance or adjustment should be performed by
Makita Authorized or Factory Service Centers, always using
Makita replacement parts.
