Loosen the six screws with a screwdriver 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 tighten with the screwdriver.
