General
safety recommendations
CAUTION! Make sure you have read
and understood all recommendations.
Failure to observe the following recom-
mendations may result in electric shock,
cause re and / or serious injuries. The term
"power tool", used in this manual refers to the
tools equipped with a power supply cord or a
battery.
Working space
•The workstation should be kept tidy and well-lit.
Disorder at the workstation and inadequate lighting
may result in accidents.
• Do not use power tools in environment exposed
to the risk of explosion, e.g. near ammable liquid
vapours, gases or ammable particles in the form of
dusts. During operation, sparks are generated, which
may ignite dust or vapours.
•Do not allow children and unauthorised persons near
places where operations with the use of an electric tool
are carried out. Third parties may distract the operator's
attention, and he may loose control over the tool.
Electric safety recommendations
•The tool plug should always be inserted to an
appropriate socket. This reduces the risk of electric
shock. Do not use plug adapters with grounding
contacts.
•Avoid touching grounded items, such as metal
pipes, heaters, cookers and refrigerators. If the
worker's body comes into contact with a grounded
item, the danger of electric shock increases.
•Protect the power tool against rain and moisture.
Penetration of water into the tool increases the danger
of electric shock.
•Do not use the power supply cable for purposes
other than designed. Under no circumstances should
one use the cable to carry the tool or pull it; also, it is
forbidden to switch off the tool by pulling the power
supply cable. Protect the cable against heating,
contact with kerosene-based bodies, with sharp
edges or mobile parts of the tool. A power cable
that is damaged or spliced increases the danger of
electric shock.
• When working in open air, use extension cords
designed for this type of work, which will reduce the
danger of electric shock.
Personal protection recommendations
•Be cautious when working with power tools, and
carefully plan your actions. Do not use the tool when
fatigued, or under the inuence of drugs, alcohol or
medicines. Careless handling may result in serious
injuries.
•Use personal protection equipment. Always wear
protective goggles. When necessary, use respirators,
non-slipping boots, hard hats and earplugs. The use
of personal protection equipment is one of the factors
that reduce the risk of injuries.
• Avoid incidental activation of power tools. Before
inserting the plug, make sure that the power switch is in
OFF position. When carrying the tool, take your ngers
off the main switch, which will reduce the possibility of
incidental activation.
• Before switching on the tool, remove any wrenches
and other objects from its rotating parts. A wrench left
in the rotating unit may result in serious injuries.
• Do not apply excessive force, take a stable position
and always try to keep balance - this will facilitate
control over the tool.
•Do not wear loose clothes or freely-hanging
jewellery. Hair, parts of garment and gloves should
be protected against contact with moving parts of the
power tool.
• If the tool is equipped with a dust collection device,
make sure that the device has been activated and
used properly. Use of such devices helps reduce the
concentration of dust at the workstation.
Use and handling of power tools
•The persons with lowered psychophysical or mental
aptitudes as well as children can not operate the power
tool, if they are not supervised or instructed about use
of the power tool by a person responsible for their
safety.
• Do not overload the tool. Power tools are to be used
only in operations, to which they have been designed,
which will ensure safety and help achieve better
results.
•Do not use power tools with a damaged power
switch. A tool that cannot be switched on and off in a
controlled manner is potentially dangerous and must
be repaired immediately.
•Before adjustment operations, replacement of
attachments, and during storage, remove the power
tool plug from the mains socket. This eliminates the
risk of the tool being unintentionally activated.
•The tool should be stored out of children's reach.
Do not allow the use of power tools by persons who
have not read this manual and are inexperienced.
In the hands of an inexpert person, the tool may
be dangerous both for the operator and his
environment.
•Take proper care of the tool condition. Monitor the
axial run-out and stability of movable parts' joints, and

13
English
pay proper attention at any faults that may result in the
tool damage. Bad condition of power tools is a frequent
cause of accidents.
•Cutting tools should be kept clean and must be well-
sharpened. Cutting tools with sharp cutting edges,
which are properly xed reduce the risk of seizure and
facilitate the control over power tools.
•When using power tools and its accessories, follow
the instructions listed in this manual. During work with a
specic type of power tools, follow recommendations,
taking into account operational conditions and the
type of job performed.
Service of power tools
Your power tool should be serviced only by qualied
specialists, with the use of recommended spare parts.
This will guarantee labour safety, when your tool is
being applied.
•
Safety guidelines during
power tool operation
Avoid stopping an electric tool motor when loaded.
•Maintain a stable position while working, hold the
electric tool with two hands.
• Never remove any chips or fragments with your
electric tool's motor running.
•Before starting work, make sure where hidden
electric cables and water and gas pipes are situated.
Damaging the electric supply wiring or engineering
communications may cause a severe harm to the
operator's life and health.
• If the working schedule cannot exclude damaging
the main supply cables, they have to be de-energized.
•When working, follow the position of the power
supply cable. Avoid winding it around your legs or
arms.
• Use only sharp and awless borers and chisels, it
will make operating the electric tool easier.
• Never change the borer and chisel design or
use attachments and appliances, which are not
recommended for your electric tool.
• When working, never press the electric tool too
hard, as this might lead to the borer or chisel seizing
and motor overloading.
•Avoid the drill, borer and chisel seizing in the
material worked in. If this happens, do not try to
release them with your perforator's motor. It may
damage the motor.
•Never force out the drills, borers or chisels stuck
in the material you are working on with a hammer
or other objects the chipped off metal particles may
harm both the operator and the persons who are
nearby.
• Avoid overheating your electric tool, when using it
for a long time.
• Never use a chisel to drill holes.

prove that the dust protection casing 2 is
not damaged. In the case of damage the
dust protection casing 2 is to be replaced
immediately at the specialized DWT Service
Centre.
Borers DWT PLUS and DWT MAX, due to
the design peculiarities of chucks DWT PLUS
and DWT MAX, can move freely within a
certain range. This is why a radial run-out
appears at no-load idle running, which is automatically
centred at drilling. It does not inuence hole-drilling
accuracy.
•Before installing the borer (chisel), clean it and apply
a thin oil layer.
• Move xing bush 3back and hold it in this position
(see g. 6).
•When mounting, insert (slightly twisting) the borer
(chisel) into the chuck 1(DWT PLUS) or the chuck 15
(DWT MAX) against stop. When removing, extract the
borer (chisel) from the chuck 1(DWT PLUS) or the
chuck 15 (DWT MAX).
• Release xing bush 3.
• Test the borer (chisel) xing by trying to remove
it from chuck 1(DWT PLUS) or from chuck 15
(DWT MAX).
Gloves are to be used when removing the
borer (chisel) from chuck 1 (DWT PLUS)
or from chuck 15 (DWT MAX), as the
borer (chisel) may be dangerously hot
after long drilling.

become very warm; use gloves to
remove it.
•
Initial operation of the
power tools
Always use the correct supply voltage the power
supply voltage must match the information quoted on
the power tool identication plate.
•The power tool is supplied properly lubricated and
ready for use.
•A new power tool needs some time for its parts to
run in before a full load operation. The run-in period
duration is about 5 hours of operation.
•The gear lubrications require a short time to get warm.
Depending on the ambient temperature this period of
time can alter within the range of approximately 15 s
(at ambient temperature of 32°С) up to 2 minutes (at
ambient temperature of 0°С).
Switching the power
tool on / off
Switching on:
Press on / off switch 11.

[BH12-40 V]
Light indicator 18 is on when the power tool is
connected to the mains and is ready to be switched on.
Recommendations
on the power tool operation
Wear thick soft gloves when working to
reduce vibration impact on your body.
•Always use additional handle 4when working, it will
ensure a better control of your electric tool and reduce
recoil.
•At impact drilling the result does not depend on the
pressing force you apply to your electric tool, which is
due to the impact mechanism design. This is why do
not exert excessive pressure on your electric tool, as it
may result in borer seizing and motor overload.
•In order to decrease dust production when drilling
holes in walls and ceilings, take actions indicated in
g. 12. Mount dust collector 14 as shown in gure 12
for drilling holes in the ceilings.
[BH09-26, BH11-28, BH14-32]
Caution: drill wood and metals in the
impactless drilling operation mode only.
•Grease the drill bit regularly when drilling holes in
metals (except drilling non-ferrous metals and their
alloys).
•When drilling hard metals, apply more force to the
power tool and lower the rotation speed.
• When drilling large diameter holes in metal, rst
drill a hole with a smaller diameter and ream it till the
necessary diameter (see. g. 13).
• In order to avoid splitting of the surface at an exit
point of a drill bit when drilling holes in wood, follow the
instructions shown in gure 13.
•When drilling holes in glazed ceramic tiles, in
order to improve the drill centering accuracy and to
save the glaze from damage, apply adhesive tape
to the presumed hole center and drill after that (see
g. 14). Caution: drill tiles in the impactless drilling
operation mode only.
Power tool maintenance /
preventive measures
Before carrying out any works on the power tool it
must be disconnected from the mains.
The power tool lubricant quantity has to be checked
on a regular basis after every three hours of operation,
as well as after replacing the carbon brushes. In order
to do that, use ange wrench 13 to release cap 9
(for BH12-40 V unscrew cap 9by hand), check the
lubricant quantity and add it, if needed. Greases with
a boiling point over 390°С are to be used.
Cleaning of the power tool
An indispensable condition for a safe long-term
exploitation of the power tool is to keep it clean.
Regularly ush the power tool with compressed air
thought the ventilation slots 8.

Recommandations générales
de sécurité
AVERTISSEMENT! Assurez-vous que
vous avez lu et compris toutes les
recommandations. La nonobservation
des recommandations suivantespeut
conduire à une décharge électrique, un incendie
et / ou de graves blessures. Le terme "outil
électrique" utilisé dans ce manuel fait allusion
aux outils équipés d'un cordon d'alimentation
électrique ou d'une batterie.
Espace de travail
• L'espace de travail devrait toujours être bien rangé
et bien éclairé. Du désordre dans l'espace de travail
et un éclairage insufsant peuvent conduire à des
accidents.
•Ne pas utiliser d'outils électriques dans un
environnement sujet au risque d'explosion, par ex. à
proximité de vapeurs liquides inammables, de gaz ou
de particules inammables sous forme de poussières.
Pendant l'opération, les étincelles sont produites, ce
qui pourrait enammer la poussière ou les vapeurs.
•Ne pas laisser des enfants et des personnes
non autorisées s'approcher des endroits où sont
effectuées des opérations avec un outil électrique. Des
personnes extérieures pourraient distraire l'attention
de l'opérateur et il pourrait perdre le contrôle de l'outil.
Recommandations concernantla sécurité électrique
• La prise de courant de l'outil doit toujours être insérée
dans une prise appropriée. Cela réduit le risque de
décharge électrique. Ne pas utiliser d'adaptateurs de
prise de courant avec des prises de mise à la terre.
• Éviter de toucher des articles reliés à la terre, comme
des tuyaux métalliques, des radiateurs, des cuisinières
et des réfrigérateurs. Si le corps de l'ouvrier entre du
contact avec un article relié à la terre, le danger de
décharge électrique augmente.
•Protégez l'outil électrique contre la pluie et l'humidité.
Si de l'eau pénètre dans l'outil, cela augmente le
danger de décharge électrique.
•Ne pas utiliser le câble d'alimentation électrique pour
un but autre que celui pour lequel il est conçu. Sous
aucune circonstance le câble ne doit être utilisé pour
porter ou tirer l'instrument; ne jamais non plus éteindre
l'outil en tirant sur le câble d'alimentation électrique.
Protéger le câble contre la chaleur, le contact avec des
corps à base de pétrole, avec des bords pointus ou
les parties mobiles de l'outil. Un câble d'alimentation
endommagé ou entortillé augmente le danger de
décharge électrique.
• Lors du travail en plein air, utiliser des rallonges
conçues pour ce type de travail, ce qui réduira le
danger de décharge électrique.
Recommandations de protection personnelle
• Soyez prudent lorsque vous travaillez avec des
outils électriques et planiez soigneusement vos
actions. Ne vous servez pas de l'outil lorsque vous
êtes fatigué ou sous l'inuence de drogues, d'alcool
ou de médicaments. Une manipulation négligente peut
conduire à de graves blessures.
•Utilisez un équipement de protection personnelle.
Portez toujours des lunettes de protection. Si
nécessaire, utilisez un respirateur, des bottes
antidérapantes, un casque et des protèges-
tympan. L'utilisation d'un équipement de protection
personnelle est un des facteurs qui réduit le risque
de blessures.
•Évitez de mettre accidentellement en marche
l'outil électrique. Avant d'insérer la prise de courant,
assurez-vous que l'outil est en position OFF. Lorsque
vous portez l'outil, retirez vos doigts de l'interrupteur
de mise en marche, cela réduira la possibilité de mise
en marche accidentelle.
• Avant d'allumer l'outil, enlevez toute clé et autres
objets laissé dans ses parties rotatives. Une clé
oubliée dans l'unité rotative peut conduire à de graves
blessures.
•Ne forcez pas trop, prenez une position ferme et
essayez toujours de garder l'équilibre; cela facilitera
votre contrôle sur l'outil.
• Ne portez pas de vêtements lâches ou de bijoux qui
pendent. Les cheveux, les parties de vêtement et les
gants devraient être protégés contre le contact avec
les parties mobiles de l'outil électrique.
•Si l'outil est équipé d'un accessoire ramasse-
poussière, assurez-vous que l'accessoire est activé et
utilisé correctement. L'utilisation de tels accessoires
permet de réduire la concentration de la poussière
dans l'espace de travail.
Utilisation et emploi des outils électriques
•Les personnes physiquement ou mentalement
handicapées, ainsi que les enfants, ne peuvent utiliser
cet outil que sous contrôle ou selon instructions des
personnes responsables de leur sécurité.
•Ne surchargez pas l'outil. Les outils électriques
ne doivent être utilisés que pour des opérations
pour lesquelles ils ont été conçus, ce qui garantira
que la sécurité et permettra d'accomplir de meilleurs
résultats.
• N'utilisez pas d'outils électriques avec un
interrupteur de mise en marche endommagé. Un
outil qui ne peut pas être allumé et éteint de manière
contrôlée est potentiellement dangereux et doit être
réparé immédiatement.
• Avant les opérations de réglage, de remplacement
des accessoires et pendant l'entreposage, débranchez

20
Français
la prise de l'outil électrique. Cela élimine le risque de
mise en marche involontaire de l'outil.
• L'outil devrait être entreposé hors de portée des
enfants. Ne pas laisser des personnes qui n'ont pas
lu ce manuel se servir de l'outil électrique. Dans les
mains d'une personne inexpérimentée, l'outil peut
être dangereux à la fois pour l'utilisateur et pour son
environnement.
• Prenez bien soin de l'état de l'outil. Surveillez l'usure
des axiaux et la stabilité des articulations des parties
mobiles et faites attention aux défauts qui peuvent
conduire à l'endommagement de l'outil. Un outil
électrique en mauvais état est une cause fréquente
d'accidents.
• Les instruments coupants devraient être gardés
propres et bien aiguisés. Les instruments coupants dont
les lames sont bien aiguisées et qui sont correctement
attachées réduisent le risque de grippage et facilitent
le contrôle sur les outils électriques.
• Lorsque vous utilisez des outils électriques et des
accessoires, suivez les instructions données dans ce
manuel. Pendant le travail avec un type spécique
d'outil électrique, suivez les recommandations, en
tenant compte des conditions opérationnelles et du
type de travail effectué.
Service des outils électriques
L'entretien de votre outil électrique ne devrait être
coné qu'à des spécialistes qualiés, avec l'utilisation
de pièces de rechange recommandées. Cela garantira
la sécurité de la main-d'œuvre appliquée à votre
instrument.

Directives de sécurité pendant l'utilisation de
l'outil électrique
Évitez d'arrêter le moteur d'un outil électrique
lorsqu'il est sous charge.
• Gardez une position ferme en travaillant, tenez
l'outil électrique à deux mains.
• N'enlevez jamais les éclats ou fragments sur votre
outil électrique lors qu'il est en marche.
• Avant de commencer un travail, assurez-vous
de savoir où se trouvent les câbles électriques
et les conduites d'eau et de gaz cachés. Le fait
d'endommager le l d'alimentation électrique ou la
construction mécanique peut entraîner des blessures
graves ou mettre la vie de l'opérateur en danger.
• Si le programme de travail ne peut pas exclure le fait
d'endommager les câbles d'alimentation principaux,
ceux-ci doivent être mis hors tension.
• Lorsque vous travaillez, suivez la position du câble
d'alimentation électrique. Évitez de l'enrouler autour
de vos jambes ou de vos bras.
• N'utilisez que des trépans et des ciseaux parfaitement
tranchants, cela facilitera le fonctionnement de l'outil
électrique.
• Ne changez jamais la conception du trépan et du
ciseau et n'utilisez pas d'accessoires ou d'appareils qui
ne sont pas recommandés pour votre outil électrique.
• Lorsque vous travaillez, n'appuyez jamais trop fort
sur l'outil, cela pourrait provoquer un grippage du
trépan ou du ciseau et une surcharge du moteur.
• Évitez de gripper l'alésoir, le trépan et le ciseau dans
le matériau travaillé. Si cela se produit, n'essayez pas
de les libérer avec le moteur de votre perforeuse. Cela
pourrait l'abîmer.
• N'essayez jamais de retirer les alésoirs, trépans ou
ciseaux coincés dans le matériau que vous travaillez
en forçant avec un marteau ou d'autres objets les
éclats de particules en métal pourraient blesser
l'opérateur et les personnes qui sont proches.
• Évitez de faire surchauffer votre outil électrique en
l'utilisant de façon prolongée.
• N'utilisez jamais un ciseau pour percer des trous.
