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.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 rear cover.
Fig.7
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
Fig.9
Fig.10
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. Remove the crank cap using a
Makita lock nut wrench 35 (optional accessory). 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 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. Reinstall the crank cap and tighten with the
lock nut wrench. Do not tighten the crank cap
excessively. It is made of resin and is subject to
breakage.
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.
