GENERAL SAFETY RULES – FOR ALL BATTERY OPERATED 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
1. Work Area
(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. Power tools create sparks which may ignite the
dust of fumes.
(3) Keep bystanders children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
2. Electrical Safety
(1) A battery operated tool with integral batteries or a separate battery pack must be
recharged only with the specified charger for the battery.
A charger that may be suitable for one type of battery may create a risk of fire when
used with another battery.
(2) Use battery operated tool only with specifically designed battery pack.
Use of any other batteries may create a risk of fire.
3. Personal Safety
(1) 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.
(2) 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.
(3) Avoid accidental starting. Be sure switch is off position before inserting battery.
Carrying tools with your finger on the switch or inserting the battery pack into a tool
with the switch on invites accidents.
(4) 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.
(5) Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enable better control of the tool in unexpected situations.
(6) Use safety equipment. Always wear eye protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.
4. Tool Use and Care
(1) 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.
4
English
(2) 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.
(3) 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.
(4) Disconnect battery pack from tool or place the switch in the locked or off position
before making any adjustments, changing accessories, or storing the tools. Such
preventive safety measures reduce the risk of starting the tool accidentally.
(5) Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
(6) When battery pack is not in use, keep it away from other metal objects like: paper
clips, coins, keys, nails, screws, or other small metal objects that can make a
connection from one terminal to another.
Shorting the battery terminals together may cause sparks, burns, or a fire.
(7) 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.
(8) 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.
(9) Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool, may become hazardous when used on
another tool.
5. Service
(1) Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
(2) 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 Instruction may create a risk of electric shock or injury.
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.

(–5°C — 60°C)
Battery capacity (Ah)
2.0 Ah
4. Disconnect battery charger from the receptacle.
CAUTION:
Do not pull the plug out of the receptacle by pulling on the cord.
Make sure to grasp the plug when removing from receptacle to avoid damaging cord.
5. Remove the battery from the battery charger.
Supporting the battery charger by hand, pull out the battery from the battery charger.
Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have not been used
for an extended period is not activated, the electric discharge might be low when using
them the first and second time. This is a temporary phenomenon, and normal time
required for recharging will be restored by recharging the batteries 2 – 3 times.
How to make the batteries perform longer.
䡬 Recharge the batteries before they become completely exhausted.
When you feel that the power of the tool becomes weaker, stop using the tool and
recharge its battery. If you continue to use the tool and exhaust the electric current, the
battery may be damaged and its life will become shorter.
16
English
䡬 Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after use. If such a battery is recharged
immediately after use, its internal chemical substance will deteriorate, and the battery life
will be shortened. Leave the battery and recharge it after it has cooled for a while.
CAUTION:
● When the battery charger has been continuosly used, the battery charger will heated,
thus constituting the cause of the failures. Once the charging has been completed, give
15 minutes rest until the next charging.
● If the battery is rechraged when it is warm due to battery use or exposure to sunlight,
the pilot lamp may light in green.
The battery will not be recharged. In such a case, let the battery cool before charging.
BEFORE USE
Check the work area to make sure that it is clear of debris and clutter.
Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.

6. HAMMER to ROTATION changeover
(Fig. 9)
The Hammer Drill can be switched from
HAMMER (hammer plus rotation) to ROTATION (rotation only) by turning the change
lever. When boring concrete, stone, tile or
similar hard materials, turning the change
lever to HAMMER side. The drill head hammers against the material while continuing
to rotate.
When boring metal, wood or plastic, turning
the change lever to ROTATION side. The
hammer drill can be used as an ordinary
electric drill.
CAUTION:
Do not use the Hammer Drill in the HAMMER function if the material can be bored by
rotation only. Such action will not only reduce drill efficiency, but may also damage the
drill tip.
NOTE
The change lever may not turn smoothly when changing from hammer drill mode to drill
mode. (Fig. 9)
In this case, operate the machine for few seconds.
The spindle shaft will then be pushed forward, and the change lever can be moved
smoothly.

7. High-speed/Low-speed changeover (Fig.
10)
Prior to changing speed, ensure that the
hammer drill has come to a complete stop.
To change speed, depress the shift lock and
slide in to the appropriate direction, as indicated by the arrow in Fig. 10. The numeral "1"
engraved in the hammer drill body denotes
low speed, the numeral "2" denotes high
speed.
CAUTION:
When changing the rotational speed with the shift lock, confirm that the switch is off.
Changing the speed while the motor is rotating will damage the gears.

8. Attaching the angle unit. (Optional accessory)
(1) Removing keyless chuck from hammer drill
(Fig. 11)
䡬 To remove the keyless chuck from the ham-
mer drill, open the keyless chuck jaws as far
as possible and turn out the locking screw
(left hand thread). This screw locks the keyless chuck to the spindle. Install the hex. bar
wrench into the keyless chuck. Place the
accessory wrench in the hexagonal opening
of the angle unit spindle. Tightly restrain the
hammer drill on a firm base. Turn the keyless
chuck until the wrench is at about a 30° angle
to the bench top and strike the wrench sharply
with a hammer so the keyless chuck turns in
the counterclockwise direction (viewed from
the front side). This should loosen the keyless chuck from the spindle which has a right
hand thread and you will be able to remove
the keyless chuck by hand.
CAUTION:
If the keyless chuck cannot be removed by striking the wrench, don’t strike the wrench
forcibly and send the hammer drill to a HITACHI AUTHORIZED SERVICE CENTER.

(2) Attaching the angle unit.
䡬
After removing the keyless chuck, rotate the
change letter to ROTATION side. Engage the
coupling to the hammer drill spindle, fit the
joint sleeve to the gear cover, attach the angle
unit to the other end of the joint sleeve, and
turn the angle unit slightly in either direction
so the hex. hole in the coupling engages the
hex. portion of the angle unit spindle. Adjust
the direction of the angle unit and tighten the
joint sleeve by clamping bolts.
Tighten two clamping bolts equally and
gradually in turn with a torque of 61-70 lnlbs. (70-80kgf·cm) (extent of force which can
be subjected by only a wrist with the open
end wrench provided to tight clamping bolts.).
(Fig. 12)
䡬 To operate the angle unit at low speed, at-
tach the keyless chuck to the angle unit spindle
at the side marked “LOW” and secure the
locking screw. At this setting, the drilling
speed is decreased to about 70% and the
drilling torque is increased to about 150%.

䡬 To operate the angle unit at high speed,
attach the keyless chuck to the angle unit
spindle at the side marked “HIGH” and secure the locking screw. At this setting, the
drilling speed is increased to about 150% and
the drilling torque is decreased to about 70%.
(Fig. 13)
(3) Installing the side handle and handle joint
(Fig. 14)
The side handle and handle joint can be
installed on either side of the angle unit for
right or left handed use. To install the side
handle and handle joint, thread it into the
socket on the desired side of the angle unit
and tighten it securely.
(4) Removing keyless chuck from angle unit
䡬 The keyless chuck can be removed from angle unit in the same manner it was removed
from the impact drill; however, ALWAYS REMOVE ANGLE UNIT FROM THE HAMMER
DRILL BEFORE ATTEMPTING TO LOOSEN KEYLESS CHUCK. This will prevent damage
of hammer drill’s gear. Use open end wrench provided to hold angle unit spindle before
attempting to loosen keyless chuck.
CAUTION:
If the keyless chuck cannot be removed by striking the wrench, don’t strike the wrench
forcibly and send the hammer drill to a HITACHI AUTHORIZED SERVICE CENTER.

HOW TO USE
1. Switch operation
䡬 When the switch trigger is depressed, the tool rotates. When the switch trigger is
released, the tool stops.
䡬 The rotational speed of the hammer drill can be controlled by varying the amount that
the switch trigger is pulled. Speed is low when the switch trigger is pulled slightly and
increases as the switch trigger is pulled more.
䡬 When releasing the switch trigger, the brake will be applied for immediate stopping.
2. When using as a Drill or an Hammer Drill
(1) Pressing force of the hammer drill
You cannot drill holes more quickly even if you press the hammer drill with a stronger
force than necessary. It not only damages tip of drill bit and decreases the efficiency of
operation, but also shortens the life of the drill tip.
(2) In case of penetrating holes
Drill bits can be broken when the material being drilled is penetrated. It is important to
decrease pressing force just before penetrating.
21
English
WARNING
The hammer drill operates with high torque.
The larger the drill bit diameter, the larger the reactive force on your arm.
Be careful not to lose control of the hammer drill because of this reactive force.
To maintain firm control, establish a good foothold, use the side handle and handle joint,
hold the hammer drill tightly with both hands, and ensure that the hammer drill is
vertical to the material being drilled.
CAUTION
● Motor may be installed when in proper drill bit is used. If the motor is locked, turn off
the switch immediately.
● In continuous operation, conduct no-load operation for five seconds after completing a
drilling job.

MAINTENANCE AND INSPECTION
WARNING: Be sure to turn off the switch and remove the battery before maintenance
and inspection.
1. Inspecting the drill bits
Since use of a dull tool will cause motor malfunctioning and degraded efficiency, replace
the drill bit with a new one or resharpening without delay when abrasion is noted.
2. Inspecting the screws
Regularly inspect all screws and ensure that they are fully tightened. Should any of the
screws be loosened, retighten them immediately.
WARNING: Using this drill with loosened screws is extremely dangerous.
3. Maintenance of the motor
The motor unit winding is the very “heart”’ of the power tool. Exercise due care to ensure
the winding does not become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes (Fig. 15)
The motor employs carbon brushes which
are consumable parts. Since and excessively
worn carbon brush can result in motor
trouble, replace the carbon brush with new
ones when it becomes worn to or near the
“wear limit”. In addition, always keep carbon
brushes clean and ensure that they slide
freely within the brush holders.
NOTE:
When replacing the carbon brush with a new
one, be sure to use the Hitachi Carbon Brush
Code No. 999058.

5. Replacing carbon brushes
Take out the carbon brush by first removing
the brush cap and then hooking the protrusion
of the carbon brush with a slotted-head screw
driver, etc., as shown in Fig. 16, Fig. 17.
When installing the carbon brush, choose
the direction so that the nail of the carbon
brush (Fig. 16) agrees with the contact portion
outside the brush tube (Fig. 18). Then push it
in with a finger.
Lastly, install the brush cap.
