Remove the crank cap using a hex wrench. Rest the tool on
003243
the table with the bit end pointing upwards. This will allow the
1
old grease to collect inside the crank housing.

Wipe out the old grease inside and replace with a fresh
003247
grease (60 g; 2 oz). Use only Makita genuine hammer
grease (optional accessory). Filling with more than the spec-
ified 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 hex wrench.
Connect the two terminals and reinstall the handle.

• Be careful not to damage the terminals or lead wires
