IMPORTANT SAFETY INFORMATION
Read and understand all of the safety precautions, warnings and operating
instructions 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.
MEANINGS OF SIGNAL WORDS

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
eliminates the need for the three
wire grounded power cord and 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) Do not 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 tires 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.
5
English
(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 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 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 tool’s 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 with 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 “
” or the words “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:
Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble
this power tool, and only genuine HITACHI replacement parts should be installed.
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.

Prior to driving in wood screws, make pilot holes suitable for them in the wooden
board. Apply the bit to the screw head grooves and gently drive the screws into
the holes.
After rotating the rotary hammer at low speed for a while until a wood screw in
partly driven into the wood, squeeze the trigger more strongly to obtain the
optimum driving force.
CAUTION:
Exercise care in preparing a pilot hole suitable for the wood screw taking the
hardness of the wood into consideration. Should the hole be excessively small
or shallow, requiring much power to drive the screw into it, the thread of the
wood screw may sometimes be damaged.
