Replacing carbon brushes
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. 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.
Use a hex wrench to remove the rear cover.
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.
Lubrication
This tool requires no hourly or daily lubrication because it
has a grease-packed lubrication system. It should be relubri-
cated after every 6 months of operation. Send the complete
tool to Makita Authorized or Factory Service Center for this
lubrication service. However, if circumstances require that
you should lubricate it by yourself, proceed as follows.
Run the tool for several minutes to warm it up. Switch off and
unplug the tool.
Remove the crank cap using a Makita lock nut wrench 35
(optional accessory). Rest the tool on the table with the bit
end pointing upwards. This will allow the old grease to collect
inside the crank housing.
