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. 4 & 5)
Whenever carbon brushes must be replaced, they cut
out the tool automatically. When this occurs, remove
the holder cap plates and then replace both carbon
brushes at the same time. Use only identical carbon
brushes.
Lubrication (Fig. 6 & 7)
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.
First, switch off and unplug the tool. Remove the
plate 50 using a screwdriver, then replenish with
fresh grease (15 g). Use only Makita genuine grease
(optional accessory). Filling with more than the speci-
fied amount of grease (approx. 15 g) can cause faulty
hammering action or tool failure. Fill only with the
specified amount of grease. Reinstall plate 50 and
secure with the screws.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by
a Makita Authorized Service Center.
