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.
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 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) 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.

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 protective grasses. 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 lose 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 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.
6. Never touch moving parts.
Never place your hands, fingers or other body parts near the tool’s moving parts.
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.
8. Use right tool.
Don’t force small tool or attachment to do the job of a heavy-duty tool.
Don’t use tool for purpose not intended —for example —don’t use circular saw for
cutting tree limbs or logs.

be used until repaired.
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.
18. Carefully handle power tools.
Should a power tool be dropped or struck against hard materials inadvertently, it may
be deformed, cracked, or damaged.
19. Do not wipe plastic parts with solvent.

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 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.
