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.

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.  
If operating a power tool in a damp location is  
unavoidable, use a residual current device  
(RCD) protected supply. Use of an RCD reduces  
the risk of electric shock.

10. Use of power supply via a RCD with a rated  
residual current of 30mA or less is always  
recommended.  
Personal safety  
11. 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

instructions may result in electric shock, fire and/or  
serious injury.  
operating power tools may result in serious  
personal injury.  
12. Use personal protective equipment. Always  
wear eye protection. Protective equipment such  
as dust mask, non-skid safety shoes, hard hat, or  
hearing protection used for appropriate conditions  
will reduce personal injuries.  
13. Prevent unintentional starting. Ensure the  
switch is in the off-position before connecting  
to power source and/or battery pack, picking  
up or carrying the tool. Carrying power tools with  
your finger on the switch or energising power tools  
that have the switch on invites accidents.  
14. 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.  
15. Do not overreach. Keep proper footing and  
balance at all times. This enables better control  
of the power tool in unexpected situations.  
16. 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.  
17. If devices are provided for the connection of  
dust extraction and collection facilities,  
ensure these are connected and properly used.  
Use of dust collection can reduce dust-related  
hazards.  
Save all warnings and  
instructions for future reference.  
The term "power tool" in the warnings refers to your  
mains-operated (corded) power tool or battery-operated  
(cordless) power tool.  
Work area safety  
1.  
2.  
Keep work area clean and well lit. Cluttered or  
dark areas invite accidents.  
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.  
Keep children and bystanders away while  
operating a power tool. Distractions can cause  
you to lose control.  
3.  
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.  
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

power tool will do the job better and safer at the  
rate for which it was designed.  
19. 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.  
20. 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.  
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.  
6.  
Be sure the bit is secured in place before  
operation.  
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.  
21. 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.  
22. Maintain power tools. Check for misalignment  
or binding of moving parts, breakage of parts  
and any other condition that may affect the  
power tool’s operation. If damaged, have the  
power tool repaired before use. Many accidents  
are caused by poorly maintained power tools.  
23. Keep cutting tools sharp and clean. Properly  
maintained cutting tools with sharp cutting edges  
are less likely to bind and are easier to control.  
24. Use the power tool, accessories and tool bits  
etc. in accordance with these instructions,  
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.  
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.  
Always be sure you have a firm footing.  
Be sure no one is below when using the tool in  
high locations.  
8.  
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.  
Service  
15. Some material contains chemicals which may  
be toxic. Take caution to prevent dust  
inhalation and skin contact. Follow material  
supplier safety data.  
25. 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.  
SAVE THESE INSTRUCTIONS.  
26. Follow instruction for lubricating and  
changing accessories.  
27. Keep handles dry, clean and free from oil and

grease.  
DO NOT let comfort or familiarity with product  
(gained from repeated use) replace strict adherence  
to safety rules for the subject product.  
MISUSE or failure to follow the safety rules stated in  
this instruction manual may cause serious personal  
injury.  
GEB004-6  
HAMMER SAFETY WARNINGS  
1.  
2.  
3.  
Wear ear protectors. Exposure to noise can  
cause hearing loss.  
Use auxiliary handle(s), if supplied with the  
tool. Loss of control can cause personal injury.  
Hold power tool by insulated gripping  
surfaces, when performing an operation where  
the cutting accessory may contact hidden  
wiring or its own cord. Cutting accessory  
contacting a "live" wire may make exposed metal  
parts of the power tool "live" and could give the  
operator an electric shock.

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.

001146  
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.  
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.

Use a screwdriver to remove the brush holder caps. Take  
out the worn carbon brushes, insert the new ones and  
secure the brush holder caps.  
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
