MAINTENANCE
CAUTION:
•
Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.
•
Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may
result.
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.

Run the tool for several minutes to warm it up. Switch off
and unplug the tool.
Loosen three hex bolts which secure the crank cap cover
and remove the crank cap. 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; 2 oz). Use only Makita genuine hammer
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 specified amount of grease.
Reinstall the crank cap and crank cap cover and tighten
the three screws with the hex wrench.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized or Factory Service Centers, always
using Makita replacement parts.
