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

WARNING indicates a potentially hazardous situations which, if ignored, could result in death or serious injury.

CAUTION indicates a potentially hazardous situations which, if not avoided, may result in minor or moderate

injury, or may cause machine damage.

NOTE emphasizes essential information.

SAFETY

GENERAL POWER TOOL SAFETY WARNINGS

WARNING:

Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated

(cordless) power tool.

1) Work area safety

a) Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

b) 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.

c) Keep children and bystanders away while

operating a power tool.

Distractions can cause you to lose control.

2) Electrical safety

a) Power tool plugs must match the outlet.

Never modify the plug in any way.

Do not use any adapter plugs with earthed

(grounded) power tools.

Unmodified plugs and matching outlets will

reduce risk of electric shock.

b) Avoid body contact with earthed or grounded

surfaces such as pipes, radiators, ranges and

refrigerators.

There is an increased risk of electric shock if

your body is earthed or grounded.

c) Do not expose power tools to rain or wet

conditions.

Water entering a power tool will increase the

risk of electric shock.

d) Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool.

Keep cord away from heat, oil, sharp edges

or moving parts.

Damaged or entangled cords increase the risk

of electric shock.

e) When operating a power tool outdoors, use

an extension cord suitable for outdoor use.

Use of a cord suitable for outdoor use reduces

the risk of electric shock.

f) If operating a power tool in a damp location

is unavoidable, use a residual current device

(RCD) protected supply.

Use of an RCD reduces the risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use

common sense when operating a power tool.

Do not use a power tool while you are tired

or under the influence of drugs, alcohol or

medication.

01Eng_DH40FR_US 5/25/12, 8:433

English

A moment of inattention while operating power

tools may result in serious personal injury.

b) Use personal protective equipment. Always

wear eye protection.

Protective equipment such as dust mask, non-

skid safety shoes, hard hat, or hearing

protection used for appropriate conditions

will reduce personal injuries.

c) Prevent unintentional starting. Ensure the

switch is in the off-position before connecting

to power source and/or battery pack, picking

up or carrying the tool.

Carrying power tools with your finger on the

switch or energising power tools that have

the switch on invites accidents.

d) Remove any adjusting key or wrench before

turning the power tool on.

A wrench or a key left attached to a rotating part

of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and

balance at all times.

This enables better control of the power tool

in unexpected situations.

f) Dress properly. Do not wear loose clothing

or jewellery. Keep your hair, clothing and

gloves away from moving parts.

Loose clothes, jewellery or long hair can be

caught in moving parts.

g) If devices are provided for the connection of

dust extraction and collection facilities, ensure

these are connected and properly used.

Use of dust collection can reduce dust-related

hazards.

4) Power tool use and care

a) Do not force the power tool. Use the correct

power tool for your application.

The correct power tool will do the job better

and safer at the rate for which it was designed.

b) Do not use the power tool if the switch does

not turn it on and off.

Any power tool that cannot be controlled with

the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source

and/or the battery pack from the power tool

before making any adjustments, changing

accessories, or storing power tools.

Such preventive safety measures reduce the

risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of

children and do not allow persons unfamiliar

with the power tool or these instructions to

operate the power tool.

Power tools are dangerous in the hands of

untrained users.

e) Maintain power tools. Check for

misalignment or binding of moving parts,

breakage of parts and any other condition

that may affect the power tool’s operation.

If damaged, have the power tool repaired

before use.

Many accidents are caused by poorly

maintained power tools.

f) Keep cutting tools sharp and clean.

Properly maintained cutting tools with sharp

cutting edges are less likely to bind and are

easier to control.

g) Use the power tool, accessories and tool bits

etc. in accordance with these instructions,

taking into account the working conditions

and the work to be performed.

Use of the power tool for operations different

from those intended could result in a

hazardous situation.

5) Service

a) Have your power tool serviced by a qualified

repair person using only identical

replacement parts.

This will ensure that the safety of the power

tool is maintained.

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:

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.

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 screws

Regularly inspect all 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.

Lire et comprendre toutes les précautions de sécurité, les avertissements et les instructions de fonctionnement

dans ce mode d’emploi avant d’utiliser ou d’entretenir cet outil motorisé.

La plupart des accidents causés lors de l’utilisation ou de l’entretien de l’outil motorisé proviennent d’un non

respect des règles ou précautions de base de sécurité. Un accident peut la plupart du temps être évité si l’on

reconnaît une situation de danger potentiel avant qu’elle ne se produise, et en observant les procédures de sécurité

appropriées.

Les précautions de base de sécurité sont mises en évidence dans la section “SECURITE” de ce mode d’emploi et

dans les sections qui contiennent les instructions de fonctionnement et d’entretien.

Les dangers qui doivent être évités pour prévenir des blessures corporelles ou un endommagement de la machine

sont identifiés par AVERTISSEMENTS sur l’outil motorisé et dans ce mode d’emploi.

NE JAMAIS utiliser cet outil motorisé d’une manière qui n’est pas spécifiquement recommandée par HITACHI.

SECURITE

AVERTISSEMENTS DE SÉCURITÉ GÉNÉRAUX CONCERNANT LES OUTILS ÉLECTRIQUES

AVERTISSEMENT :

Lire tous les avertissements de sécurité et toutes les instructions

Tout manquement à observer ces avertissements et instructions peut engendrer des chocs électriques, des

incendies et/ou des blessures graves.

Conservez tous les avertissements et toutes les instructions pour vous y référer ultérieurement.

Le terme "outil électrique", utilisé dans les avertissements, se réfère aux outils électriques (câblé) ou aux

outils à piles (sans fil).

1) Sécurité de l’aire de travail

a) Maintenir l'aire de travail propre et bien

éclairée.

Les endroits encombrés ou sombres sont

propices aux accidents.

b) Ne pas utiliser d'outils électriques en présence

de liquides, gaz ou poussière inflammables,

au risque de provoquer une explosion.

Les outils électriques créent des étincelles

susceptibles d'enflammer la poussière.

c) Ne pas laisser les enfants et les visiteurs

s'approcher de vous lorsque vous utiliser un

outil électrique.

Les distractions peuvent faire perdre le contrôle.

2) Sécurité électrique

a) Les prises de l'outil électrique doivent

correspondre à la prise secteur.

Ne jamais modifier la prise.

Ne pas utiliser d'adaptateurs avec les outils

électriques mis à la masse.

Les prises non modifiées et les prises secteurs

correspondantes réduisent les risques de

choc électrique.

b) Eviter tout contact avec les surfaces mises à

la masse telles que les tuyaux, radiateurs,

bandes et réfrigérateurs.

Le risque de choc électrique est accru en cas

de mise à la masse du corps.

c) Ne pas exposer les outils électriques à la pluie

ou à des conditions humides.

Si l'eau pénètre dans l'outil, cela augmente

les risques de choc électrique.

d) Ne pas utiliser le cordon à tort. Ne jamais

utiliser le cordon pour transporter ou

débrancher l'outil électrique.

Maintenir le cordon loin de la chaleur, de

l'huile, des bords pointus ou des pièces

mobiles.

Les cordons endommagés ou usés

augmentent les risques de choc électrique.

Français

e) En cas d'utilisation d'un outil électrique à

l'extérieur, utiliser un cordon de rallonge

adapté à un usage extérieur.

L'utilisation d'un cordon adapté à l'usage

extérieur réduit les risques de choc électrique.

f) Si vous devez utiliser un outil électrique dans

un endroit humide, utilisez une alimentation

protégée contre les courants résiduels.

L'utilisation d'un dispositif de protection

contre les courants résiduels réduit le risque

de choc électrique.

3) Sécurité personnelle

a) Restez alerte, regarder ce que vous faites et

usez de votre bon sens en utilisant un outil

électrique.

Ne pas utiliser d'outil électrique si vous êtes

sous l'influence de drogues, d'alcool ou de

médicaments.

Pendant l'utilisation d'outils électrique, un

instant d'inattention peut entraîner des

blessures graves.

b) Utiliser un équipement de protection

individuelle. Toujours porter des verres de

protection.

L'utilisation d'équipements de protection tels

que les masques anti-poussière, les chaussures

de sécurité anti-dérapantes, les casques ou les

protections auditives dans des conditions

appropriées réduisent les risques de blessures.

c) Empêcher les démarrages intempestifs.

Veiller à ce que l'interrupteur soit en position

d'arrêt avant de brancher à une source

d'alimentation et/ou une batterie, de

ramasser l'outil au sol ou de le transporter.

Transporter les outils électriques avec le doigt

sur l'interrupteur ou brancher les outils

électriques avec l'interrupteur en position de

marche peut entraîner des accidents.

d) Retirer toute clé de sécurité ou clé avant de

mettre l'outil électrique en marche.

Laisser une clé ou une clé de sécurité sur une

partie mobile de l'outil électrique peut

engendrer des blessures.

e) Ne pas trop se pencher. Toujours garder une

bonne assise et un bon équilibre pendant le

travail.

Cela permet un meilleur contrôle de l'outil

électrique dans des situations imprévisibles.

f) Porter des vêtements adéquats. Ne pas

porter de vêtements amples ni de bijoux.

Maintenir les cheveux, les vêtements et les

gants loin des pièces mobiles.

Les vêtements amples ou les cheveux longs

peuvent se prendre dans les pièces mobiles.

g) En cas de dispositifs destinés au

raccordement d'installations d'extraction et

de recueil de la poussière, veiller à ce qu'ils

soient correctement raccordés et utilisés.

L'utilisation d'un dispositif de collecte de la

poussière peut réduire les dangers associés

à la poussière.

4) Utilisation et entretien d'un outil électrique

a) Ne pas forcer sur l'outil électrique. Utiliser

l'outil électrique adapté à vos travaux.

Le bon outil électrique fera le travail mieux et

en toute sécurité au régime pour lequel il a

été conçu.

b) Ne pas utiliser l'outil électrique si

l'interrupteur ne le met pas en position de

marche et d'arrêt.

Tout outil ne pouvant être contrôlé par

l'interrupteur est dangereux et doit être réparé.

c) Débrancher la prise ou retirer la batterie avant

de procéder à des réglages, au remplacement

des accessoires ou au stockage des outils

électriques.

Ces mesures préventives de sécurité

réduisent les risques de démarrage accidentel

de l'outil électrique.

d) Stockez les outils électriques inutilisés hors

de la portée des enfants et ne pas laisser des

personnes non familiarisées avec l'outil ou

ces instructions utiliser l'outil électrique.

Les outils électriques sont dangereux entre

les mains d'utilisateurs non habilités.

e) Entretenir les outils électriques. Vérifier

l'absence de mauvais alignement ou d'arrêt,

d'endommagement de pièces ou toute autre

condition susceptible d'affecter l'opération de

l'outil.

Si l'outil est endommagé, le faire réparer

avant utilisation.

De nombreux accidents sont dus à des outils

mal entretenus.

f) Maintenir les outils coupants aiguisés et

propres.

Des outils coupants bien entretenus avec des

bords aiguisés sont moins susceptibles de se

coincer et plus simples à contrôler.

g) Utiliser l'outil électrique, les accessoires et

les mèches de l'outil, etc. conformément à

ces instructions en tenant compte des

conditions d'utilisation et du travail à réaliser.

L'utilisation de l'outil électrique pour des

opérations différentes de celles pour

lesquelles il a été conçu est dangereuse.

5) Service

a) Faire entretenir l'outil électrique par un

technicien habilité à l'aide de pièces de

rechange identiques exclusivement.

Cela garantira le maintien de la sécurité de

l'outil électrique. lesquelles il a été conçu est

dangereuse.
