9.  
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.  
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.  
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.  
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  
under the influence of drugs, alcohol or  
medication.  
A
moment of inattention while  
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.  
Service  
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.  
26. Follow instruction for lubricating and  
changing accessories.  
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.  
27. Keep handles dry, clean and free from oil and  
grease.

ROTARY 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.  
Power tool use and care  
18. 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.  
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  
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  
3
 
mask and thickly padded gloves.  
FUNCTIONAL DESCRIPTION  
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.  
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.  
CAUTION:  
Always be sure that the tool is switched off and  
unplugged before adjusting or checking function on  
the tool.

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

Position the bit at the desired location for the hole, then  
pull the switch trigger. Do not force the tool. Light  
pressure gives best results. Keep the tool in position and  
prevent it from slipping away from the hole.  
Do not apply more pressure when the hole becomes  
clogged with chips or particles. Instead, run the tool at  
an idle, then remove the bit partially from the hole. By  
repeating this several times, the hole will be cleaned out  
and normal drilling may be resumed.  
003148  
The side grip is convenient for downward drilling or  
chipping operations. Screw the side grip on the tool  
securely. The side grip can be installed on either side of  
the tool for right or left hand operation.  
Installing or removing the bit  
CAUTION:  
There is a tremendous and sudden twisting force  
exerted on the tool/bit at the time of hole  
break-through, when the hole becomes clogged  
with chips and particles, or when striking  
reinforcing rods embedded in the concrete. Always  
use the side grip (auxiliary handle) and firmly hold  
the tool by both side grip and switch handle during  
operations. Failure to do so may result in the loss  
of control of the tool and potentially severe injury.

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.

001146  
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.  
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.  
Use a hex wrench to remove the rear cover.
