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, remove the
holder cap plates and 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.
First, switch off and unplug the tool. Remove the plate 50
using a screwdriver, then replenish with fresh grease
(60 g). Use only Makita genuine grease (optional acces-
sory). 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 plate 50 and secure with the screws.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
