adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.
Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of
electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet
16. Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
17. Do not use the power tool if the switch does
not turn it on and off. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.

18. Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
19. Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are
dangerous in the hands of untrained users.
Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords
increase the risk of electric shock.
When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.

Personal Safety
9. Stay alert, watch what you are doing and use
20. Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tools operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
21. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
22. Use the power tool, accessories and tool bits
etc. in accordance with these instructions and
in the manner intended for the particular type
of power tool, taking into account the working
conditions and the work to be performed. Use
of the power tool for operations different from
common sense when operating a power tool.
Do not use a power tool while you are tired or
under the influence of drugs, alcohol or
medication.
A
moment of inattention while
operating power tools may result in serious
personal injury.
10. Use safety equipment. Always wear eye
protection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will
reduce personal injuries.
11. Avoid accidental starting. Ensure the switch is
in the off-position before plugging in. Carrying
power tools with your finger on the switch or
plugging in power tools that have the switch on
invites accidents.

SERVICE
12. Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
23. Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
13. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
14. Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts. Loose clothes,
jewellery or long hair can be caught in moving
parts.
15. If devices are provided for the connection of
dust extraction and collection facilities,
ensure these are connected and properly used.
Use of these devices can reduce dust-related
hazards.
24. Follow instruction for lubricating and
changing accessories.
25. Keep handles dry, clean and free from oil and
grease.

SPECIFIC SAFETY RULES
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to hammer safety rules. If you use this tool unsafely
or incorrectly, you can suffer serious personal
injury.
1.
Wear ear protectors. Exposure to noise can
cause hearing loss.
Power tool use and care

2.
3.
Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
Hold power tools by insulated gripping
surfaces when performing an operation where
the cutting tool may contact hidden wiring or
its own cord. Contact with a "live" wire will make
exposed metal parts of the tool "live" and shock
the operator.
Wear a hard hat (safety helmet), safety glasses
and/or face shield. Ordinary eye or sun
glasses are NOT safety glasses. It is also
highly recommended that you wear a dust
mask and thickly padded gloves.

In cold weather or when the tool has not been
used for a long time, let the tool warm up for a
while by operating it under no load. This will
loosen up the lubrication. Without proper
warm-up, hammering operation is difficult.
Always be sure you have a firm footing.

Press the push button and pivot the tool retainer to the
side. 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.
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. Keep the carbon brushes
clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes.
CAUTION:
Use a screwdriver to remove the rear cover.

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 Service Center for
this lubrication service. However, if circumstances
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 by loosening hex bolts (3 pcs.)
securing it with a hex wrench. 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 hammer 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.

To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers,
always using Makita replacement parts.
