GENERAL SAFETY RULES GEA001-3
WARNING:
Read all instructions. Failure to follow all instructions listed below may result in
electric shock, fire and/or serious injury. The term “power tool” in all of the
warnings listed below refers to your mains-operated (corded) power tool or battery-
operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
Work area safety
1. Keep work area clean and well lit. Cluttered and
dark areas invite accidents.
2. Do not operate power tools in explosive atmos-
pheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while oper-
ating a power tool. Distractions can cause you to
lose control.
Electrical safety
4. Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.
5. 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.
6. Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the
risk of electric shock.
7. 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.
8. 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
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 protec-
tion. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal inju-
ries.
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 plug-
ging in power tools that have the switch on invites
accidents.
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.
13. Do not overreach. Keep proper footing and bal-
ance 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.
Power tool use and care
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 chil-
dren 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.

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 con-
ditions and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Service
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.
24. Follow instruction for lubricating and changing
accessories.
25. Keep handles dry, clean and free from oil and
grease.
SPECIFIC SAFETY RULES GEB004-2
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.
2. Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
3. Hold tools by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord. Con-
tact with a “live” wire will make exposed metal parts
of the tool “live” and shock the operator.
4. 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 recom-
mended that you wear a dust mask and thickly
padded gloves.
5. Be sure the bit is secured in place before opera-
tion.
6. 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.
7. 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.
8. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
9. Hold the tool firmly with both hands.
10. Keep hands away from moving parts.
11. Do not leave the tool running. Operate the tool
only when hand-held.
12. Do not point the tool at any one in the area when
operating. The bit could fly out and injure some-
one seriously.
13. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
14. Do not operate the tool at no-load unnecessar-
ily.
15. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
SAVE THESE INSTRUCTIONS
WARNING:
MISUSE or failure to follow the safety rules stated in this instruction manual

Disconnect the terminal by pulling it.
Remove the crank cap by loosening the screws with a screwdriver. 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 hammer-
ing action or tool failure. Fill only with the specified amount of grease.
Reinstall the crank cap and secure with the screws.
Connect the terminal and reinstall the handle.
CAUTION:
•Be careful not to damage the terminal or lead wires especially when
wiping out the old grease or installing the handle.
•Whenever reinstalling the handle, use the two short screws for the upper
