between 220 V and 250 V.
Switching operations of electric apparatus cause voltage
fluctuations. The operation of this device under unfavora-
ble mains conditions can have adverse effects to the
operation of other equipment. With a mains impedance
equal or less than 0.31 Ohms it can be presumed that
there will be no negative effects. The mains socket used
for this device must be protected with a fuse or protective
circuit breaker having slow tripping characteristics.

GENERAL SAFETY RULES GEA001-2
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
atmospheres, 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
operating 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 elec-
tric shock.
5. Avoid body contact with earthed or
grounded surfaces such as pipes, radia-
tors, 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
conditions. 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

4
entangled cords increase the risk of electric
shock.
8. When operating a power tool outdoors,
use an extension cord suitable for out-
door 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
protection. Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate con-
ditions will reduce personal injuries.
11. Avoid accidental starting. Ensure the
switch is in the off-position before plug-
ging in. Carrying power tools with your finger
on the switch or plugging 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 balance at all times. This enables bet-
ter control of the power tool in unexpected sit-
uations.
14. Dress properly. Do not wear loose cloth-
ing 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 cor-
rect 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 adjust-
ments, changing accessories, or storing
power tools. Such preventive safety mea-
sures 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 unfa-
miliar with the power tool or these instruc-
tions to operate the power tool. Power
tools are dangerous in the hands of untrained
users.
20. Maintain power tools. Check for misalign-
ment or binding of moving parts, break-
age 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. Prop-
erly maintained cutting tools with sharp cut-
ting 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 instruc-
tions 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 those intended
could result in a hazardous situation.
Service
23. Have your power tool serviced by a quali-
fied repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.

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.

Lubrication
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 or Factory Service
Center for this lubrication service. However, if circumstances require that you
should lubricate it by yourself, proceed as follows.
First, switch off and unplug the tool.
Remove the cap using a wrench 23, then replenish with fresh grease (60 g).
Use only Makita genuine hammer 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 the cap and secure with the wrench.
To maintain product SAFETY and RELIABILITY, repairs, any other mainte-
nance or adjustment should be performed by Makita Authorized Service Cent-
ers, always using Makita replacement parts.
