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 Man-
ual and in the sections which contain the operation and maintenance instructions.
Hazards that must be avoided to prevent bodily injuly or machine damage are identi-
fied 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

in serious personal injury.
CAUTION indicates a hazardous situations which, if ignored, could result in moderate
personal injury, or could cause machine damage.
NOTE emphasizes essential information.

English I
GENERAL SAFETY RULES
z_ WARNING :Read and understand all instructions.
Failure to follow alJ 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
toot. Distractions can cause you to lose control.
2. Electrical Safety
(1) Double Insulated tolls are equipped with a polarized plug (one blade is
wider than the other .) This plug will fit in apolarized 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 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 form 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 apower tool. Do not use tool while tired or under the influ-
ence of drugs, alcohol, or medication. A moment of inattention while oper-
ating 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.

English
(4) Remove adjusting keys or switches before turning the tool on. A wrench
or a key that is left attached to a rotating part of the tool may result in per-
sonal 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 situa-
tions.
(6) Use safety equipment. Always wear protective glasses. Dust mask, nonskid
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 astable 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 adjust-
ments, 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 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 dam-
aged, have the tool serviced before using. Many accidents are caused by
poorly maintained tools.
(8) Use only accessories that are recommended by manufacturer for your
model. Accessories that may be suitable for one tool, may become haz-
ardous when used on another tool.

DOUBLE INSULATION FOR SAFER OPERATION
To ensure safer operation of this power tool, HITACHI has adopted a double insula-
tion design. "Double insulation" means that two physically separated insulation sys-
tems have been used to insulate the electrically conductive materials connected to
the power supply from the outer frame handled by the operater. Therefore, either the
symbol "i-all"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:
_ Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assem-
ble 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.

la vitesse de rotation de ta meule telle qu'elle est indiquee sur I'etiquette de
mise en garde de I'outil. En effet, les meules et les autres accessoires qui sont
utilises & une cadence superieure a.la vitesse nominale risquent d'etre projetes
aux alentours et de blesser quelqu'un.
3. Tenir les outils par tes surfaces de grippage Iors de la realisation
d'operation ou I'outil de coupe risque d'entrer en contact avec des c&btes
caches ou son propre cordon. Un contact avec un fil "sous tension" mettra tes
parties metalligues de I'outil "sous tension" et electrocutera I'utilisateur.
