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
CAUTION:
• This servicing should be performed by Makita
Authorized or Factory Service Centers only.
This tool requires no hourly or daily lubrication because it
has a grease-packed lubrication system. Lubricate the
tool every time the carbon brushes are replaced.
Run the tool for several minutes to warm it up. Switch off
and unplug the tool.

CAUTION:
• Always remove the crank cap only after aligning the

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). Use only Makita genuine hammer grease
(optional accessory). Filling with more than the specified
amount of grease (approx. 30 g) can cause faulty
hammering action or tool failure. Fill only with the
specified amount of grease.
CAUTION:
• Be careful not to damage the connector or lead
wires especially when wiping out the old grease.
To reassemble the tool, follow the disassembling
procedure in reverse.
