NOTE:
When installing the bit with a cap, remove the cap from
the tool. Otherwise the bit with a cap cannot be installed.
To remove the bit, follow the installation procedure in
reverse.
Side grip (auxiliary handle) (Fig. 4)
The side grip swings around to either side, allowing easy
handling of the tool in any position. Loosen the side grip
by turning it counterclockwise, swing it to the desired
position and then tighten it by turning clockwise.
Switch action (Fig. 5)
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the "OFF"
position when released.
To start the tool, simply pull the trigger. Release the trig-
ger to stop. For continuous operation, pull the trigger and
then push in the lock button. To stop the tool from the
locked position, pull the trigger fully, then release it.
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. 6 & 7)
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 car-
bon brushes.
Lubrication (Fig. 8)
This tool requires no hourly or daily lubrication because it
has a grease-packed lubrication system. It should be
relubricated after every 6 months of operation. Send the
complete tool to Makita Authorized or Factory Service
Centre for this lubrication service. However, if circum-
stances require that you should lubricate it by yourself,
proceed as follows.
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 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 (30 g). Use only Makita genuine grease (optional
accessory). 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.
