ADDITIONAL SAFETY RULES

1. Wear a hard hat (safety helmet), safety glasses
and/or face shield. It is also highly recom­mended that you wear a dust mask, ear pro­tectors and thickly padded gloves.

2. Be sure the bit is secured in place before
operation.

3. Under normal operation, the tool is designed
to produce vibration. The screws can come
loose easily, causing a breakdown or accident.
Check tightness of screws carefully before
operation.

4. In cold weather or when the tool has not been
used for a long time, let the tool warm up for
several minutes by operating it under no load.
This will loosen up the lubrication. Without
proper warm-up, hammering operation is dif­ficult.

5. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.

6. Hold the tool firmly with both hands.

7. Keep hands away from moving parts.

8. Do not leave the tool running. Operate the tool
only when hand-held.

9. Do not point the tool at any one in the area
when operating. The bit could fly out and
injure someone seriously.

10. When chipping into walls, floors or wherever
“live” electrical wires may be encountered, DO
NOT TOUCH ANY METAL PARTS OF THE
TOOL!
Hold the tool by the insulated grasping sur­faces to prevent electric shock if you chip into
a “live” wire.

11. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.

OPERATING INSTRUCTIONS

Installing grip (Fig. 1)

Install the grip securely with the bolts using the hex
wrench.

Installing or removing bull point or other bits
(cold chisel, etc.) (Fig.2&3)

Important:
Always be sure that the tool is switched off and
unplugged before installing or removing the bit.

Turn up the tool retainer. With the notched portion of
the bit facing the tool retainer, insert the bit into the
tool barrel as far as it will go.

Return the tool retainer to its original position to
secure the bit.

To remove the bit, follow the installation procedure in
reverse.

Switch action (Fig. 4)

CAUTION:

•

Before plugging in the tool, always check to see that
the switch lever actuates properly and returns to the
‘‘OFF’’ position when released.

•

Do not tape, tie or otherwise secure the switch lever
in the ‘‘ON’’ position.

To start the tool, simply squeeze the switch lever.
Release the switch lever 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 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,
maintenance or adjustment should be carried out by a
Makita Authorized Service Center.
