GENERAL SAFETY RULES

USA002-2

(For All Tools)

WARNING:

Read and understand all instructions. Failure to follow all

instructions listed below, may result in electric shock, fire and/or
serious personal injury.

SAVE THESE INSTRUCTIONS

3.

Work A re a

1.

Keep your work area clean and well lit.

Cluttered benches and dark areas invite acci­dents.

2.

Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Powe r

tools create sparks which may ignite the dust
or fumes.

2

Keep bystanders, children, and visitors
away while operating a power tool. Distrac-

tions can cause you to lose control.

Electrical Safety

4.

Double insulated tools are equipped with
a polarized plug (one blade is wider than
the other.) This plug will fit in a polarized
outlet only one way. If the plug does not fit
fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified elec-

trician to install a polarized outlet. Do not
change the plug in any way. Double insula-

tion eliminates the need for the three wire
grounded power cord and grounded power
supply system.

5.

Avoid body contact with grounded sur­faces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of

electric shock if your body is grounded.

6.

Do not expose power tools to rain or wet
conditions. Water entering a power tool will

increase the risk of electric shock.

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.

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.

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.

10.

Dress properly. Do not wear loose cloth­ing 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 ser­viced before using. Many accidents are

caused by poorly maintained tools.

22.

Use only accessories that are recom­mended by the manufacturer for your
model. Accessories that may be suitable for

3

one tool, may become hazardous when used
on another tool.

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.

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 num­ber, 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 “live” wire will

make exposed metal parts of the tool “live”
and shock the operator.

2.

Wear ear protectors when using the tool
for extended periods. Prolonged exposure
to high intensity noise can cause hearing
loss.

4

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.

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.

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 lubrica­tion. Without proper warm-up, hammering
operation is difficult.

7.

Always be sure you have a firm footing.
Be sure no one is below when using the
tool in high locations.

8.

Hold the tool firmly with both hands.

9.

Keep hands away from moving parts.

10.

Do not leave the tool running. Operate the
tool only when hand-held.

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.

13.

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

CAUTION:

• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.

Switch action

1. Switch trigger

ASSEMBLY

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.

Torque l imit er

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.

CAUTION:

• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.

CAUTION:

1. Side grip

the clamp screw to secure the depth gauge.

NOTE:

• The depth gauge cannot be used at the position where
the depth gauge strikes against the tool body.

Dust cup (optional accessory)

Use the dust cup to prevent dust from falling over the tool
and on yourself when performing overhead drilling opera­tions. 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.

Bit diameter
6 mm (1/4”) - 14.5 mm (9/16”)
12 mm (15/32”) - 16 mm (5/8”)

OPERATION

8

Hammer drilling 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 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.

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.

002449

Blow-out bulb (optional accessory)

After drilling the hole, use the blow-out bulb to clean the dust
out of the hole.

003223

Drilling in wood or metal

Use the optional drill chuck assembly. When installing it, refer
to “Installing or removing the bit” described 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.

CAUTION:

• 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 hold­down device.

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.

003229

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.

Lubrication

003234

This tool requires no hourly or daily lubrication because it
has a grease-packed lubrication system. Lubricate the tool
every time the carbon brushes are replaced.

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 28
(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.

003245

Wipe out the old grease inside and replace with a fresh

1

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.

Reinstall the crank cap and tighten with the lock nut wrench.

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.

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.
