Switch action (Fig. 4)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to
the "OFF" position when released.
• Do not tape, tie or otherwise secure the trigger in
the "ON" position.
To start the tool, simply pull the trigger. Release the
trigger to stop.
Chipping / Scaling / Demolition
Hold the tool firmly with both hands. Turn the tool on
and apply slight pressure on the tool so that the tool
will not bounce around, uncontrolled. Pressing very
hard on the tool will not increase the efficiency.
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 accessory). Filling with more than the speci-
fied 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,
maintenance or adjustment should be carried out by a
Makita Authorized Service Center.
