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.
Reinstall the holder cap plates firmly.
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 hex wrench, then replenish
with fresh grease (60 g; 2 oz). Use only Makita genuine ham-
mer grease (optional accessory). Filling with more than the
specified amount of grease (approx. 60 g; 2 oz) can cause
faulty hammering action or tool failure. Fill only with the spec-
ified amount of grease.
Reinstall the crank cap securely with the hex wrench.
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.
