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 circumstances 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
(30
g;
1
02).
Use only Makita genuine grease (optional accessory). Filling with more than
the specified amount of grease (approx. 30
g;
1
02)
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. Do not tighten the crank cap excessively.
