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 after every 6 months of operation. 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.
Wipe out the old grease inside and replace with a fresh
grease (60 g). Use only Makita genuine hammer grease
(optional accessory). Filling with more than the specified
amount of grease (approx. 60 g) can cause faulty ham-
mering action or tool failure. Fill only with the specified
amount of grease.
