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.

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
circumstances 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; 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.
