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 atmo-

spheres, 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 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.

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 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 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.

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 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 recom­mended that you wear a dust mask and thickly
padded gloves.

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

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 warm­up, 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 some­one 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 unnecessarily.

15. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.

Installing or removing the bit

There is a raised dimple on one of the faces of the tool
retainer handle where you grip it. Pull out and then turn
the tool retainer so that the dimple faces toward the large
opening in the end of the tool (tool holder). The shank of
the bit is then inserted into the tool holder with the
notched portion on the shank facing back toward the tool
retainer. Insert the bit into the tool holder as far as it will
go.

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.

Run the tool for several minutes to warm it up. Switch off
and unplug the tool.

Remove the crank cap using a Makita lock nut wrench 35
(optional accessory). Rest the tool on the table with the
bit end pointing upwards. This will allow the old grease to
collect inside the crank housing.

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.

Wipe out the old grease inside and replace with a fresh
grease (30 g; 1 oz). Use only Makita genuine hammer
grease (optional accessory). Filling with more than the
specified amount of grease (approx. 30 g; 1 oz) can
cause faulty hammering action or tool failure. Fill only
with the specified amount of grease.

CAUTION:

• Do not tighten the crank cap excessively. It is made

of resin and is subject to breakage.

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