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.
After replacing brushes, insert the battery cartridge into the
tool and break in brushes by running tool with no load for
about 1 minute. Then check the tool while running and elec-
tric brake operation when releasing the switch trigger. If elec-
tric 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.
