MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Replacement of carbon brushes (Fig. 10 & 11)
Whenever carbon brushes must be replaced, they cut out
the tool automatically. When this occurs, replace both
carbon brushes at the same time. Use only identical car-
bon brushes.
Lubrication (Fig. 12 & 13)
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 Mak-
ita 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 (60 g). Use only Makita genuine 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 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, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
