OPERATING INSTRUCTIONS
Installing or removing bit (Fig. 1 & 2)
Important:
Always be sure that the tool is switched off and
unplugged before installing or removing the bit.
Pull the change ring down all the way and insert the bit
into the tool holder as far as it will go. Release the change
ring and it will return automatically to its original position
to secure the bit. After installing, always make sure that
the bit is securely held in place by trying to pull it out.
To remove the bit, pull the change ring down all the way
and pull the bit out.
Side grip (auxiliary handle) (Fig. 3)
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. 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.
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. 5 & 6)
Whenever carbon brushes must be replaced, they cut out
the tool automatically. When this occurs, loosen the bolts
which secure the rear cover. Remove the rear cover.
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.
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 (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 acces-
sory). 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.
