Lubrication
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. However, if circum-
stances 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.

Wipe out the old grease inside and replace with a fresh
grease (90 g; 3 oz). Use only Makita genuine hammer
grease (optional accessory). Filling with more than the
specified amount of grease (approx. 90 g; 3 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

CAUTION:
