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 identical carbon
brushes.
First, remove the cover
"A".
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.

Dressing diamond wheel
If the cutting action of the diamond wheel begins to diminish, use an old discarded coarse
grit bench grinder wheel or concrete block to dress the diamond wheel. To do this, tightly
secure the bench grinder wheel or concrete block and cut in it.
To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjust-
ment should be performed by Makita Authorized or Factory Service Centers, always using
Makita replacement parts.
