ADDITIONAL SAFETY RULES
1. Wear a hardhat (safetyhelmet), safety glasses and/or face shield. It isalso
highly recommendedthat you wear a dust mask, ear protectorsandthickly
padded gloves.
2. Be sure the bit is secured in place before operation.
3. Undernormal operation, the toolisdesignedtoproducevibration. Thescrews
can come loose easily, causing a breakdown or accident. Check tightness
of screws carefully before operation.
4. Incold weather or whenthe tool has not been used for a longtime, let the
toolwarm upfor several minutesby operating
it under noload. This will loos-
en up the lubrication. Without proper warm-up, hammering operation is
difficult.
Be sure no one is below when using the tool in high locations.
5. Always be sure you have a firm footing.
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 inthe area when operating. The bit could
fly out and injure someone seriously.

MAINTENANCE
CAUTION:
Always be sure that the tool
is switched off and unpluggedbefore attempting toperform
inspectionor maintenance.
Replacingcarbon brushes
When the resin insulating tip inside the
carbon brush
is exposed to contact the
commutator,
it will automatically shut off
the motor.
When this occurs, both carbon brushes
should be replaced
at the same time. Use
only Makitacarbonbrushes.

Lubrication
Lubricatethe tool every time the carbon brushesare replaced.
Run the tool for several minutes towarm
it
up, then rest the tool on the table with the
bit end pointing upwards. Thiswill allow
the old grease to collect inside the crank
housing. After five minutes, take off the
crank cap and remove the old grease. Wipe
out all grease inside and replace with
a
fresh supply (30 g; 1 oz).
CAUTION :
0 Filling with more than the specified
amount of grease (approx.309;
1 oz.) can
cause faulty hammering action or tool
failure. Fill only with the specified
amount of grease.
The use of any other grease may harm the
tool.
0 Use only Makitagenuine grease.
Sharpeningtungstencarbidetip bit
When your bit becomes dull, use
an ordinary bench grinder with a wheel made of silicon
carbide toresharpen
it.
CAUT I 0 N :
.Be sure to maintain the original angles of the tip. Especially without 60" chamfering,
0 Do notquench the bitinwater or oil.
0 Do notgrindthe sides B and C.
the tungsten-carbidetip may be damaged.
To maintain product SAFETY and RELlABlLITY, repairs, any other maintenance or
