Chipping / Scaling / Demolition (Fig. 4)
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 (Fig. 5, 6 & 7)
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.
• 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.
• Reinstall the holder cap plates firmly.
Lubrication (Fig. 8 & 9)
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.
• Run the tool for several minutes to warm it up. Switch
off and unplug the tool.
• Remove the crank cap using a hex wrench, 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 crank cap securely with the hex wrench.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
