OPERATION
Chipping/Scaling/Demolition
Hold the tool firmly with both hands. Turn the tool on and
apply slight pressure on the tool so that the tool will not
bounce around, uncontrolled. Pressing very hard on the
tool will not increase the efficiency.
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.
Replacing carbon brushes
Fig.6
When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically
shut off the motor. When this occurs, both carbon
brushes should be replaced. Keep the carbon brushes
clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes.
Use a hex wrench to remove the motor housing cover.

Lubrication
Fig.10
Fig.11
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.
First, switch off and unplug the tool.
Remove the cap using a lock nut wrench 20 or hex
wrench 8, then replenish with fresh grease (60 g). Use
only Makita genuine hammer grease (optional
accessory). Filling with more than the specified amount
of grease (approx. 60 g) can cause faulty hammering
action or tool failure. Fill only with the specified amount
of grease.

Reinstall the cap and secure with the wrench.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers,
always using Makita replacement parts.
