SAFETY
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.
4
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 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.
(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 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.
(5) Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hand 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 “
words and “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.

HOW TO USE THE DEMOLITION HAMMER
1. After placing the tip of the accessory, such as a bull point,
etc. 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 lockon button will release.
2. In some cases, it is necessary to thrust the tip of the
accessory, such as a bull point, a cutter, etc. against the
crushing position forcibly in order to begin the striking
motion.
This is not due to malfunction of this demolition hammer. It
means that the safe guard mechanism against no-load
striking is working.
3. By utilizing the empty weight of this demolition hammer
and by firmly holding this demolition 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.

functioning to securely hold the accessory shank portion. If any wear and tear is found,
bring this demolition hammer to an authorized service center for maintenance service.
4. Inspecting the carbon brushes (Fig. 8)
The Motor employs carbon brushes which
are consumable parts. When they become
worn to or near the “wear limit”, it results
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.
