change the plug in any way. Double insula-  
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.  
tion  
eliminates the need for the three wire  
grounded power cord and grounded power  
supply system.  
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.  
5. Avoid body contact with grounded sur-  
faces such as pipes, radiators, ranges and  
refrigerators. There is an increased risk of  
electric shock if your body is grounded.  
Tool Use and Care  
6. Do not expose power tools to rain or wet  
conditions. Water entering a power tool will  
increase the risk of electric shock.  
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  
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.  
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.  
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  
3
 
one tool, may become hazardous when used  
on another tool.  
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.  
SERVICE  
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.  
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  
USB010-2  
DO NOT let comfort or familiarity with product (gained from  
repeated use) replace strict adherence to rotary hammer safety  
rules. If you use this tool unsafely or incorrectly, you can suffer  
serious 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.  
3. 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.  
4. Be sure the bit is secured in place before  
operation.  
2. Wear ear protectors when using the tool  
for extended periods. Prolonged exposure  
to high intensity noise can cause hearing  
loss.  
5. Under normal operation, the tool is  
designed to produce vibration. The  
screws can come loose easily, causing a  
4
 
breakdown or accident. Check tightness  
of screws carefully before operation.  
10. Do not leave the tool running. Operate the  
tool only when hand-held.  
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-  
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.  
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.  
7. Always be sure you have a firm footing.  
Be sure no one is below when using the  
tool in high locations.  
13. Some material contains chemicals which  
may be toxic. Take caution to prevent dust  
inhalation and skin contact. Follow mate-  
rial supplier safety data.  
8. Hold the tool firmly with both hands.  
9. Keep hands away from moving parts.

FUNCTIONAL  
DESCRIPTION  
CAUTION:  
Always be sure that the tool is switched off and  
unplugged before adjusting or checking function on the  
tool.  
003105  
Switch action  
CAUTION:  
1
Before plugging in the tool, always check to see that the  
switch trigger actuates properly and returns to the OFF”  
position when released.  
To start the tool, simply pull the switch trigger. Tool speed is  
increased by increasing pressure on the switch trigger.  
Release the switch trigger to stop.  
1. Switch trigger  
Torque limiter  
The torque limiter will actuate when a certain torque level is  
reached. The motor will disengage from the output shaft.  
When this happens, the bit will stop turning.  
CAUTION:  
As soon as the torque limiter actuates, switch off the tool  
immediately. This will help prevent premature wear of the  
tool.  
Hole saws, core bits, diamond core bits, etc. cannot be  
used with this tool. They tend to pinch or catch easily in  
the hole. This will cause the torque limiter to actuate too  
frequently.  
ASSEMBLY  
CAUTION:  
Always be sure that the tool is switched off and  
unplugged before carrying out any work on the tool.  
003142  
Side grip (auxiliary handle)

Dust cup (optional accessory)  
Use the dust cup to prevent dust from falling over the tool  
and on yourself when performing overhead drilling opera-  
tions. Attach the dust cup to the bit as shown in the figure.  
The size of bits which the dust cup can be attached to is as  
follows.

Hammer drilling operation  
OPERATION  
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 slip-  
ping 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 sev-  
eral times, the hole will be cleaned out and normal drilling  
may be resumed.  
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.

Drilling in wood or metal  
1
Use the optional drill chuck assembly. When installing it, refer  
to Installing or removing the bitdescribed on the previous  
page.  
You can drill up to 13 mm (1/2) diameter in metal and up to  
24 mm (15/16) diameter in wood.  
2
CAUTION:  
1. Drill chuck  
2. Chuck adapter  
Pressing excessively on the tool will not speed up the  
drilling. In fact, this excessive pressure will only serve to  
damage the tip of your bit, decrease the tool  
performance and shorten the service life of the tool.  
There is a tremendous twisting force exerted on the tool/  
bit at the time of hole breakthrough. Hold the tool firmly  
and exert care when the bit begins to break through the  
workpiece.  
Always secure small workpieces in a vise or similar hold-  
down device.  
MAINTENANCE  
CAUTION:  
Always be sure that the tool is switched off and  
unplugged before attempting to perform inspection or  
maintenance.  
001146  
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.

2. Crank cap  
003245  
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 speci-  
fied amount of grease (approx. 30 g; 1 oz) can cause faulty  
hammering action or tool failure. Fill only with the specified  
amount of grease.

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.
