Use a screwdriver to remove the brush holder caps. Take out
003229
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
003234
has a grease-packed lubrication system. Lubricate the tool
every time the carbon brushes are replaced.
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 28
(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.
Wipe out the old grease inside and replace with a fresh
003245
grease (30 g; 1 oz). Use only Makita genuine hammer
grease (optional accessory). Filling with more than the speci-
fied amount of grease (approx. 30 g; 1 oz) can cause faulty
hammering action or tool failure. Fill only with the specified
amount of grease.
Reinstall the crank cap and tighten with the lock nut wrench.
CAUTION:
• Do not tighten the crank cap excessively. It is made of
resin and is subject to breakage.
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.
