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.
Replacing carbon brushes
1
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 screwdriver to remove the holder cap plates.
2
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.

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 circum-
stances require that you should lubricate it by yourself,
proceed as follows.
First, switch off and unplug the tool.
Remove the plate 50 using a screwdriver, then replenish
with 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.
