GENERAL SAFETY RULES

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) 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
electrician to install a polarized outlet. Do not change the plug in any way. Double

Insulation
grounded power supply system.

(2) 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.

(3) Don’t expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electric shock.

(4) Do not abuse the cord. Never use the cord to carry the tools or pull the plug from a

receptacle. Keep cord away from heat, oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged cords increase the risk of electric shock.

(5) 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.

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 before plugging in. Carrying tools with

your finger on the switch or plugging in tools that have the switch on invites accidents.

eliminates the need for the three wire grounded power cord and

English

(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 enables better control of the tool in unexpected situations.

(6) Use safety equipment. Always wear protective glasses. 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.

(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 the plug form 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.

(5) Store idle tools out of reach of children and other untrained persons. Tools are

dangerous in the hands of untrained users.

(6) 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.

(7) 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.

(8) 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.

DOUBLE INSULATION FOR SAFER OPERATION

To ensure safer operation of this power tool, HITACHI has adopted a double insulation
design. “Double insulation “ means that two physically separated insulation systems have
been used to insulate the electrically conductive materials connected to the power supply
from the outer frame handled by the operator. Therefore, either the symbol “
“Double insulation” appear on the power tool or on the nameplate.
Although this system has no external grounding, you must still follow the normal electrical
safety precautions given in this Instruction Manual, including not using the power tool in wet
environments.
To keep the double insulation system effective, follow these precautions:
䡬 Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this

power tool, and only genuine HITACHI replacement parts should be installed.

䡬 Clean the exterior of the power tool only with a soft cloth moistened with soapy water,

and dry thoroughly.
Never use solvents, gasoline or thinners on plastic components; otherwise the plastic
may dissolve.

ASSEMBLY AND OPERATION

APPLICATIONS

䡬 Demolishing concrete, chiseling concrete, grooving, bar cutting, and driving piles.

Application examples:
Installation of piping and wiring, sanitary facility installation, machinery installation,
water supply and drainage work, interior jobs, harbor facilities and other civil engineering
works.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms to the power source requirements
specified on the product nameplate.

2. Power switch

Ensure that the switch is in the OFF position. If the plug is connected to a receptacle while
the switch is in the ON position, the power tool will start operating immediately and can
cause serious injury.

3. Extension cord

When the work area is far away from the power source, use an extension cord of sufficient
thickness and rated capacity. The extension cord should be kept as short as practicable.

WARNING: Damaged cord must be replaced or repaired.

4. Check the receptacle

If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact
a licensed electrician to make appropriate repairs.
If such a fautly receptacle is used, it may cause overheating, resulting in a serious hazard.

5. Confirming condition of the environment:

Confirm that the work site is placed under appropriate conditions conforming to
prescribed precautions.

6 Feeding oil (refer to the paragraph on oil feeding)

Prior to using the power tool, remove the oil gauge and do not fail the oil tank with the
provided oil. (Although the oil tank is built in, it contains only a small volume of oil when
shipped from the Hitachi Works.)

7. Installing Tools

CAUTION: To prevent accidents, make sure to turn the switch off and disconnect the

plug from the receptacle.

NOTE:

When using tools such as bull points, cutters, etc., make sure to use the genuine parts
designated by our company.

HOW TO USE THE DEMOLITION HAMMER

1. After placing the tip of the tool on concrete
surface, switch ON.
The switch can be turned ON if the trigger
is pulled and OFF when it is released.
If the lock-on button is pressed while the
trigger for the switch is pulled, even if your
finger is released from the trigger, the
switch remains ON - convenient for
continuous operation.
To turn the switch OFF, pull the trigger
again, and the lock-on button will release.

2. In some cases, it is necessary to thrust the
tip of the bit against the crushing position
forcibly in order to begin the striking
motion.
This is not due to malfunction of the tool. It
means that the safe guard mechanism
against no-load striking is working.

3. By utilizing the empty weight of the machine and by firmly holding the hammer by both
hands, you can effectively control the subsequent recoil motion.
Proceed at a moderate work-rate, the use of too much pushing force will impair efficiency.

Fig. 4

NOTE:

Sometimes the tool does not begin the striking motion even when the motor rotates
because the oil has become thick.
If the tool is used at low temperatures or if it is used after being idle for a long time, the
tool should be run for five minutes in order to warm it up.

11

English

CAUTION: After long time of use, the front cover becomes hot.

Therefore, be careful not to burn your hands.

OIL FILLING

CAUTION: Prior to oil filling, always

disconnect the plug form the
receptacle.

Since an oil chamber is built in this Hitachi
Demolition Hammer, it can be used for
approximately 20 days without supplying
lubricating oil, assuming that the Hammer is
used continuously 3 – 4 hours daily.
Fill oil into the oil tank as described below
before using this Hammer. (See Figs. 5 and 6)

1. Just before no oil is visible in the oil gauge
window when the power tool is held
upright, fill oil without fail.

2. Before filling oil, use the provided wrench
to remove the oil gauge.
Be careful not to lose the rubber packing
attached below the oil gauge.

3. Check the oil level once a day, confirming
that oil is filled.

4. After filling with oil, securely clamp the oil
gauge.

NOTE:

As an optional accessory, oil for the Hitachi
Electric Hammer (one liter) is sold separately.
Use this oil when oil in the tank is depleted.

MAINTENANCE AND INSPECTION

WARNING: Be sure to switch power OFF and disconnect the plug from the receptacle

during maintenance and inspection.

1. Inspecting the tool

Since use of a dull tool will degrade efficiency and cause possible motor malfunction,
sharpen or replace the tool as soon as abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that they are properly tightened.
Should any of the screws be loosened, retighten them immediately.

WARNING: Using this demolition hammer with loosen screws is extremely

dangerous.

3. Inspecting the carbon brushes (Fig. 7)

The Motor employs carbon brushes which
are consumable parts. When they become
worn to or near the “wear limit”, it could
result in motor trouble. When an auto-stop
carbon brush is equipped, the motor will
stop automatically. At that time, replace
both carbon brushes with new ones which
have the same carbon brush Numbers shown
in the figure. In addition, always keep carbon
brushes clean and ensure that they slide
freely within the brush holders.

NOTE: Use HITACHI carbon brush No. 86 indicated in Fig. 7.
