For your personal safety, READ and UNDERSTAND before using.  
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.

6. Do not expose power tools to rain or wet  
conditions. Water entering a power tool will  
increase the risk of electric shock.  
Tool Use and Care  
15. Use clamps or other practical way to  
secure and support the workpiece to a  
stable platform. Holding the work by hand or  
against your body is unstable and may lead  
to loss of control.  
7. Do not abuse the cord. Never use the cord  
to carry the tools or pull the plug from an  
outlet. Keep cord away from heat, oil,  
sharp edges or moving parts. Replace  
damaged cords immediately. Damaged  
cords increase the risk of electric shock.  
16. Do not force tool. Use the correct tool for  
your application. The correct tool will do the  
job better and safer at the rate for which it is  
designed.  
8. When operating a power tool outside, use  
an outdoor extension cord marked “W-A”  
or “W”. These cords are rated for outdoor  
use and reduce the risk of electric shock.  
17. Do not use tool if switch does not turn it  
on or off. Any tool that cannot be controlled  
with the switch is dangerous and must be  
repaired.  
Personal Safety  
9. Stay alert, watch what you are doing and  
use common sense when operating a  
power tool. Do not use tool while tired or  
under the influence of drugs, alcohol, or  
medication. A moment of inattention while  
operating power tools may result in serious  
personal injury.  
18. Disconnect the plug from the power  
source before making any adjustments,  
changing accessories, or storing the tool.  
Such preventive safety measures reduce the  
risk of starting the tool accidentally.  
19. Store idle tools out of reach of children  
and other untrained persons. Tools are  
dangerous in the hands of untrained users.  
10. Dress properly. Do not wear loose cloth-  
ing or jewelry. Contain long hair. Keep  
your hair, clothing, and gloves away from  
moving parts. Loose clothes, jewelry, or long  
hair can be caught in moving parts.  
20. Maintain tools with care. Keep cutting  
tools sharp and clean. Properly maintained  
tools with sharp cutting edges are less likely  
to bind and are easier to control.  
11. Avoid accidental starting. Be sure switch  
is off before plugging in. Carrying tools with  
your finger on the switch or plugging in tools  
that have the switch on invites accidents.  
21. Check for misalignment or binding of  
moving parts, breakage of parts, and any  
other condition that may affect the tools  
operation. If damaged, have the tool ser-  
viced before using. Many accidents are  
caused by poorly maintained tools.  
12. Remove adjusting keys or wrenches  
before turning the tool on. A wrench or a  
key that is left attached to a rotating part of  
the tool may result in personal injury.  
22. Use only accessories that are recom-  
mended by the manufacturer for your  
model. Accessories that may be suitable for  
one tool, may become hazardous when used  
on another tool.  
13. Do not overreach. Keep proper footing  
and balance at all times. Proper footing and  
balance enables better control of the tool in  
unexpected situations.  
SERVICE  
14. Use safety equipment. Always wear eye  
protection. Dust mask, non-skid safety  
shoes, hard hat, or hearing protection must  
be used for appropriate conditions. Ordinary  
eye or sun glasses are NOT eye protection.  
23. Tool service must be performed only by  
qualified repair personnel. Service or main-  
tenance performed by unqualified personnel  
could result in a risk of injury.  
3
 
24. When servicing a tool, use only identical  
replacement parts. Follow instructions in  
the Maintenance section of this manual.  
Use of unauthorized parts or failure to follow  
Maintenance instructions may create a risk of  
electric shock or injury.  
USE PROPER EXTENSION CORD: Make sure your extension cord is in good condition.  
When using an extension cord, be sure to use one heavy enough to carry the current your  
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of  
power and overheating. Table 1 shows the correct size to use depending on cord length and  
nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage num-  
ber, the heavier the cord.

SPECIFIC SAFETY RULES  
USB009-2  
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 seri-  
ous personal injury.  
1. Hold tools by insulated gripping surfaces  
when performing an operation where the  
cutting tool may contact hidden wiring or  
its own cord. Contact with a livewire will  
make exposed metal parts of the tool live”  
and shock the operator.  
is also highly recommended that you wear  
a dust mask and thickly padded gloves.  
4. Be sure the bit is secured in place before  
operation.  
5. 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.  
2. Wear ear protectors when using the tool  
for extended periods. Prolonged exposure  
to high intensity noise can cause hearing  
loss.  
6. 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 lubrica-  
3. Wear a hard hat (safety helmet), safety  
glasses and/or face shield. Ordinary eye  
or sun glasses are NOT safety glasses. It  
4
 
tion. Without proper warm-up, hammering  
operation is difficult.  
11. Do not point the tool at any one in the area  
when operating. The bit could fly out and  
injure someone seriously.  
7. Always be sure you have a firm footing.  
Be sure no one is below when using the  
tool in high locations.  
12. Do not touch the bit or parts close to the  
bit immediately after operation; they may  
be extremely hot and could burn your  
skin.  
8. Hold the tool firmly with both hands.  
9. Keep hands away from moving parts.  
13. Some material contains chemicals which  
may be toxic. Take caution to prevent dust  
inhalation and skin contact. Follow mate-  
rial supplier safety data.  
10. Do not leave the tool running. Operate the  
tool only when hand-held.

Indicator lamp

The green power-ON indicator lamp lights up when the tool is  
plugged. The indicator lamp is lit but the tool does not start  
even if the tool is switched on, the carbon brushes may be  
worn out, or the electric circuit or the motor may be defective.  
If the indicator lamp does not light up and the tool does not  
start, the ON/OFF switch or the mains cord may be defective.  
The red service indicator lamp lights up when the carbon  
brushes are nearly worn out to indicate that the tool needs  
servicing. After approx. 8 hours of use, the motor will auto-  
matically be shut off.

MAINTENANCE  
CAUTION:  
Always be sure that the tool is switched off and  
unplugged before attempting to perform inspection or  
maintenance.

Replacing carbon brushes  
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.

tool to Makita Authorized 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.  
1. Screw  
Loosen the four screws (two short screws on the upper side  
and two long screws on the lower side. ) and remove the

WARNING  
Some dust created by power sanding, sawing, grinding, drilling, and other  
construction activities contains chemicals known to the State of California  
to cause cancer, birth defects or other reproductive harm. Some examples  
of these chemicals are:  
lead from lead-based paints,  
crystalline silica from bricks and cement and other masonry products, and  
arsenic and chromium from chemically-treated lumber.  
Your risk from these exposures varies, depending on how often you do this  
type of work. To reduce your exposure to these chemicals: work in a well  
ventilated area, and work with approved safety equipment, such as those  
dust masks that are specially designed to filter out microscopic particles.  
MAKITA LIMITED ONE YEAR WARRANTY
