out the worn carbon brushes, insert the new ones and
secure the brush holder caps.
Lubrication
CAUTION:
• This servicing should be performed by Makita
Authorized or Factory Service Centers only.
This tool requires no hourly or daily lubrication because it
has a grease-packed lubrication system. It should be
relubricated every time the carbon brushes are replaced.
Send the complete tool to Makita Authorized or Factory
Service Center for this lubrication service.
Run the tool for several minutes to warm it up. Switch off
and unplug the tool.
Loosen the six screws and remove the handle. Note that
the top screws are different from other screws.

Remove the crank cap using a hex wrench. Rest the tool
on the table with the bit end pointing upwards. This will
allow the old grease to collect inside the crank housing.
1
Wipe out the old grease inside and replace with a fresh
grease (30 g; 1 oz). Use only Makita genuine hammer
grease (optional accessory). Filling with more than the
specified amount of grease (approx. 30 g; 1 oz) can
cause faulty hammering action or tool failure. Fill only
with the specified amount of grease.
1
Reinstall the crank cap and tighten with the hex wrench.
Connect the connector and reinstall the handle.
CAUTION:
• Do not tighten the crank cap excessively. It is made
of resin and is subject to breakage.
• Be careful not to damage the terminals or lead
wires especially when wiping out the old grease or
installing the handle.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized or Factory Service Centers,
always using Makita replacement parts.
