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) 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) 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.

G12SA2_1-E.E65 8/20/02, 11:50 AM4

English

(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, 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 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. 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 by

a Hitachi authorized service center 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 a Hitachi authorized service center. 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

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.

(2) Ne pas utiliser les outils motorisés dans une atmosphère explosive, telle qu’en

présence de liquides inflammables, de gaz ou de poussières. Les outils motorisés

créent des étincelles qui risquent d’enflammer la poussière ou les vapeurs.

(3) Tenir les spectateurs, les enfants et les visiteurs éloignés, lors de l’utilisation de

l’outil motorisé. Une distraction peut faire perdre le contrôle de la machine.

2. Sécurité électrique

(1) Les outils à double isolation sont équipés d’une fiche polarisée (une lame est plus

large que l’autre). Cette fiche ne pénétrera dans une prise secteur polarisée que dans

un sens. Si la fiche ne rentre pas complètement dans la prise, la retourner. Si elle ne

rentre toujours pas, contacter un électricien qualifié pour installer une prise polarisée.

Ne pas modifier la fiche d’aucune façon. La double isolation

élimine le besoin d’un

cordon d’alimentation à trois fils et d’un système d’alimentation avec mises à la terre.

(2) Eviter tout contact corporel avec les surfaces mises à la terre telles que les

canalisations, les radiateurs, les réchauds et les réfrigérateurs. Il y a un risque accru

d’électrocution si son corps est mis à la terre.

(3) Ne pas exposer les outils motorisés à la pluie ou à l’humidité. De l’eau pénétrant à

l’intérieur de l’outil motorisé augmente le risque d’électrocution.

(4) Ne pas maltraiter le cordon d’alimentation. Ne jamais utiliser le cordon pour porter

les outils ou tirer sur la fiche du réceptacle. Garder le cordon à l’écart de la chaleur,

de l’huile, des arêtes coupantes ou des pièces en mouvement. Remplacer les cordons

endommagés immédiatement. Des cordons endommagés augmentent le risque

d’électrocution.

(5) Lors de l’utilisation d’un outil motorisé, utiliser un cordon de rallonge extérieur

marqué “W-A” ou “W”. Ces cordons sont prévus pour une utilisation extérieure et

réduisent les risques d’électrocution.

3. Sécurité personnelle

(1) Rester sur ses gardes, regarder ce que l’on fait et utiliser son sens commun lors de

l’utilisation d’un outil motorisé. Ne pas utiliser un outil en état de fatigue ou sous

l’influence de drogues, d’alcool ou de médicaments. Un moment d’inattention lors de

l’utilisation de l’outil motorisé peut entraîner de sérieuses blessures personnelles.

(2) S’habiller correctement. Ne pas porter des vêtements larges ou des bijoux. Attacher

les cheveux longs. Tenir ses cheveux, vêtements et ses gants éloignés des parties

mobiles. Les vêtements larges, les bijoux et les cheveux longs peuvent se prendre

dans les parties mobiles.

(3) Eviter tout démarrage accidentel. S’assurer que le l’interrupteur d’alimentation est

sur la position d’arrêt avant de brancher la machine. Transporter l’appareil avec les

doigts sur l’interrupteur d’alimentation ou brancher un outil avec l’interrupteur sur la

position marche invite aux accidents.

(4) Retirer les clefs d’ajustement ou les commutateurs avant de mettre l’outil sous

tension. Une clef qui est laissée attachée à une partie tournante de l’outil peut

provoquer une blessure personnelle.

(5) Ne pas trop présumer de ses forces. Garder en permanence une position et un

équilibre correct. Une position et un équilibre correct permettent un meilleur contrôle

de l’outil dans des situations inattendues.

(6) Utiliser un équipement de sécurité. Toujours porter des lunettes de protection. Un

masque à poussière, des chaussures de sécurité antidérapantes, un chapeau dur et

des bouchons d’oreille doivent être utilisés dans les conditions appropriées.

4. Utilisation de l’outil et entretien

(1) Utiliser un étau ou toutes autres façons de fixer et maintenir la pièce à usiner sur une

plate-forme stable. Tenir la pièce avec la main ou contre son corps est instable et peut

conduire à une perte de contrôle de l’outil.

(2) Ne pas forcer sur l’outil. Utiliser l’outil correct pour l’application souhaitée. L’outil

correct réalisera un meilleur et plus sûr travail dans le domaine pour lequel il a été

conçu.

(3) Ne pas utiliser un outil s’il ne se met pas sous ou hors tension avec un interrupteur.

Un outil qui ne peut pas être commandé avec un interrupteur est dangereux et doit

être réparé.

(4) Déconnecter la fiche de la source d’alimentation avant de réaliser tout ajustement,

changement d’accessoires ou pour ranger l’outil. De telles mesures de sécurité

réduisent le risque que l’outil ne démarre accidentellement.

(5) Ranger les outils inutilisés hors de la portée des enfants et des autres personnes

inexpérimentées. Les outils sont dangereux dans les mains de personnes

inexpérimentées.

(6) Conserver les outils avec soin. Garder les outils de coupe aiguisés et propres. Des

outils bien entretenus, avec des lames coupantes aiguisées risquent moins de se

gripper et sont plus faciles à contrôler.

(7) Vérifier les défauts d’alignement ou grippage des parties mobiles, les ruptures des

pièces et toutes les autres conditions qui peuvent affecter le fonctionnement des

outils. En cas de dommage, faire réparer l’outil par un centre de service HITACHI

autorisé avant de l’utiliser. Beaucoup d’accidents sont causés par des outils mal

entretenus.

(8) Utiliser uniquement les accessoires recommandés par le fabricant pour le modèle

utilisé. Des accessoires qui peuvent convenir à un outil, peuvent devenir dangereux

lorsqu’ils sont utilisés avec un autre outil.

5. Réparation

(1) La réparation de l’outil ne doit être réalisée que par un centre de service HITACHI

autorisé. Une réparation ou un entretien réalisé par un personnel non qualifié peut

entraîner des risques de blessures.

(2) Lors de la réparation d’un outil, utiliser uniquement des pièces de rechange identiques.

Suivre les instructions de la section d’entretien de ce mode d’emploi. L’utilisation de

pièces non autorisées ou un non respect des instructions d’entretien peut créer un

risque d’électrocution ou de blessures.

REGLES DE SECURITE SPECIFIQUES ET SYMBOLES

Se servir systématiquement d’un capot couvre-meule approprié. En effet, le capot couvre-

meule met l’opérateur à l’abri d’éventuelles projections de fragments de meule cassés.

2. Les accessoires doivent être utilisés à une cadence équivalent au moins à la vitesse de

rotation de la meule telle qu’elle est indiquée sur l’étiquette de mise en garde de l’outil.

En effet, les meules et les autres accessoires qui sont utilisés à une cadence supérieure

à la vitesse nominale risquent d’être projetés aux alentours et de blesser quelqu’un.

3. Tenir les outils par les surfaces de grippage lors de la réalisation d’opération où l’outil

de coupe risque d’entrer en contact avec des câbles cachés ou son propre cordon. Un

contact avec un fil “sous tension” mettra les parties métalliques de l’outil “sous tension”

et électrocutera l’utilisateur.

4. TOUJOURS porter des bouchons d’oreille lors de l’utilisation de l’outil pendant de

longues périodes.

Une exposition prolongée à un son de forte intensité peut endommager

l’ouïe de l’utilisateur.

5. Utiliser uniquement une meule à dépression centrale ayant un régime nominal

SUPERIEUR à 13 300 t/mn. L’utilisation d’une meule à dépression centrale ayant un

régime nominal INFERIEUR à 13 300 t/mn et/ou d’une meule de la mauvaise taille (voir

les SPECIFICATIONS, page 9) risque de provoquer une rupture de la meule et de projeter

des fragments de meule, ce qui pourrait entraîner la mort ou des blessures graves.

6. NE JAMAIS toucher les parties mobiles.

NE JAMAIS placer ses mains, ses doigts ou toute autre partie de son

corps près des parties mobiles de l’outil.

7. NE JAMAIS utiliser l’outil sans que tous les dispositifs de sécurité ne soient en place.

NE JAMAIS faire fonctionner cet outil sans que tous les dispositifs et caractéristiques de

sécurité ne soient en place et en état de fonctionnement. Si un entretien ou une réparation

nécessite le retrait d’un dispositif ou d’une caractéristique de sécurité, s’assurer de bien

remettre en place le dispositif ou la caractéristique de sécurité avant de recommencer à

utiliser l’outil.

8. Utiliser l’outil correct

Ne pas forcer sur un petit outil ou accessoire pour faire le travail d’un outil de grande

puissance. Ne pas utiliser un outil pour un usage pour lequel il n’a pas été prévu: par

exemple, ne pas utiliser une scie circulaire pour couper des branches d’arbre ou des

bûches.
