Maintenance - Makita HM0810T Instruction Manual

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. 5 & 6)
Whenever carbon brushes must be replaced, they cut out
the tool automatically. When this occurs, loosen the bolts
which secure the rear cover. Remove the rear cover.
Then replace both carbon brushes at the same time. Use
only identical carbon brushes.
Lubrication (Fig. 7 & 8)
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 (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 acces-
sory). 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, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Centre.
