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. 11 & 12)
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 carbon brushes.
Lubrication (Fig. 13 & 14)
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 (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 exces-
sively. It is made of resin and is subject to breakage.
To maintain product safety and reliability, repairs,
maintenance or adjustment shouldbe carried out by a
Makita Authorized Service Center.
