IMPORTANT INFORMATION
Read and understand all of the operating instructions, safety precautions and
warnings in the Instruction Manual before operating or maintaining this power tool.
Most accidents that result from power tool operation and maintenance are caused
by the failure to observe basic safety rules or precautions. An accident can often be
avoided by recognizing a potentially hazardous situation before it occurs, and by
observing appropriate safety procedures.
Basic safety precautions are outlined in the “SAFETY” section of this Instruction
Manual and in the sections which contain the operation and maintenance
instructions.
Hazards that must be avoided to prevent bodily injury or machine damage are
identified by WARNINGS on the power tool and in this Instruction Manual.
Never use this power tool in a manner that has not been specifically recommended
by HITACHI, unless you first confirm that the planned use will be safe for you and
others.

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.
SA VE 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 or 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 eliminates the need for the three wire
grounded power cord and grounded power supply system.
(2) Av oid 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, w atch what you are doing and use common sense when oper ating
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 awa y fr om moving par ts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
4
(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) 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 ear plugs 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. T ools
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.
6. Never touch moving parts.
Never place your hands, fingers or other body parts near the tool’ s moving par ts.
7. Never operate without all guards in place.
Never operate this tool without all guards or safety features in place and in proper
working order. If maintenance or servicing requires the removal of a guard or
safety feature, be sure to replace the guard or safety feature before resuming
operation of the tool.

13.Blades and accessories must be securely mounted to the tool.
Prevent potential injuries to yourself or others. Blades, cutting implements and
accessories which have been mounted to the tool should be secure and tight.
14.Keep motor air vent clean.
The tool’s motor air vent must be kept clean so that air can freely flow at all
times. Check for dust build-up frequently.
15.Operate power tools at the rated voltage.
Operate the power tool at voltages specified on its nameplate.
If using the power tool at a higher voltage than the rated voltage, it will result in
abnormally fast motor revolution and may damage the unit and the motor may
burn out.
16.Never use a tool which is defective or operating abnormally.
If the tool appears to be operating unusually, making strange noises, or otherwise
appears defective, stop using it immediately and arrange for repairs by a Hitachi
authorized service center.
17.Never leave tool running unattended. Turn power off.
Don’t leave tool until it comes to a complete stop.

DOUBLE INSULATION FOR SAFER OPERATION
T o ensure safer operation of this power tool, HIT ACHI 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 “ ” or the 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 CEN TER should disassemble or assemble
this power tool, and only genuine HIT ACHI 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.

MAINTENANCE AND INSPECTION
WARNING: Be sure to switch power OFF and disconnect the plug from the
receptacle during 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 mounting screws
Regularly inspect all mounting screws and ensure that they are properly
tightened. Should any of the screws be loose, retighten them immediately.
WARNING: Using this rotary hammer with loosen 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. 18)
The motor employs carbon brushes which are consumable parts. When they
become worn to or near “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 Nos. shown in the figure.
In addition, always keep carbon brushes clean and ensure that they slide freely
within the brush holders.
CAUTION: Using this rotary hammer with a carbon brush which is worn in
excess of the wear limit will damage the motor.
