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
4
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.

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

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.

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.
