•  If the tool is used in cold-temperature 
conditions (such as during winter) or if 
it is frequently stopped during use, the 
overheating protection feature may not 
activate.
•  The ambient temperature range is 
between 0°C (32°F) and 40°C (104°F).
If the battery pack is used when the 
battery temperature is below 0°C 
(32°F), the tool may fail to function 
properly.
•  When charging a cool battery pack 
(below 0°C (32°F)) in a warm place, 
leave the battery pack at the place and 
wait for more than one hour to warm 
up the battery to the level of the ambi-
ent temperature.
•  The performance of the EY9L42 dete-
riorates significantly at and below 10°C 
due to work conditions and other fac-
tors.
(3) Battery low warning lamp
Off
(normal 
operation)Flashing
(No charge)
Battery protection 
feature active
Excessive (complete) discharging of 
lithium ion batteries shortens their service 
life dramatically. The driver includes a 
battery protection feature designed to 
prevent excessive dis charging of the 
battery pack.
•  The battery protection feature acti-
vates immediately before the battery 
loses its charge, causing the battery 
low warning lamp to flash.
•  If you notice the battery low warning 
lamp flashing, charge the battery pack 
immediately.
•  If it is started with too little battery 
power remaining, the tool may stop 
operating without the battery low warn-
ing lamp flashing first. This indicates 
that there is too little battery power 
remaining to use the tool, and the bat-tery pack should be charged before 
further use.
•  If the tool is subject to a sudden load 
during use that causes the motor to 
lock up, the overdischarge preven-
tion sensor may be triggered, and the 
battery low warning lamp may flash. 
The lamp will stop flashing once you 
address the cause of the motor’s lock-
ing up and cycle the trigger.
•  The battery protection feature may 
activate when a high load is abrupt-
ly placed on the motor, even if ample 
battery charge remains. In this case, 
both the battery low warning lamp and 
LED light will flash.
•  If both the battery low warning lamp 
and LED light flash, reduce the force 
with which you are pushing on the 
driver or, if using a drill driver, adjust 
the speed switch to a lower setting.
Recommended Grip
Use the grip to hold and operate the 
driver with one hand. If the job requires 
additional force, you can push against 
the rear end of the driver with your other 
hand.

min d’eau à température normale est 
projetée sur l’outil a 3 mètre de distance 
pendant 3 minutes avec une lance de 
12,5 mm de diamètre intérieur).
GARANTIE LIMITÉE
Le code IP56 rend possible un impact 
minimum d’eau et de poussière sur 
cet outil mais il n’en garantit pas les 
performances dans de telles condi-
tions. Veuillez lire la notice d’utilisation 
et de sécurité pour plus de détails 
quant à un fonctionnement approprié.
I. CONSIGNES 
DE SECURITE 
GENERALES
 
AVERTISSEMENT!  Veuillez lire 
toutes les instructions.
Si les instructions détaillées ci-dessous ne 
sont pas observées, cela peut entraîner 
une électrocution, un incendie et/ou des 
blessures graves. Le terme “outil méca-
nique” utilisé dans tous les avertissements 
ci-dessous se réfère aux outils mécaniques 
opérés par cordons d’alimentation et par 
batterie (sans fi l).
CONSERVEZ CES INSTRUCTIONS
Sécurité de la zone de travail
 1)  Gardez la zone de travail propre 
et bien aérée.
    Les endroits encombrés et sombres 
invitent les accidents.
 2)  Ne faites pas fonctionner les 
outils mécaniques dans des at-
mosphères explosives, comme 
en présence de liquides inflam-
mables, de gaz ou de poussière.   Les outils mécaniques génèrent 
des étincelles qui peuvent enflam-
mer la poussière ou les vapeurs.
 3)  Gardez les enfants et les specta-
teurs éloignés lors du fonctionne-
ment d’un outil mécanique.
    Les distractions peuvent en faire per-
dre le contrôle.
Sécurité électrique
 1)  
La fiche des outils mécaniques doit 
correspondre aux prises secteur. 
Nemodifiez la fiche sous aucun pré-
texte. N’utilisez pas de fiche adapta-
trice avec les outils mécaniques mis 
à la terre.
   Des fiches non modifiées et des 
prises secteur correspondant rédu-
isent les risques d’électrocution.
 2)  Evitez tout contact physique avec 
les surfaces mises à la terre telles 
que tuyaux, radiateurs, micro-
ondes et réfrigérateurs.
  
Il y a un risque d’électrocution supplémen-
taire si votre corps est mis à la terre.
 3)  N’exposez pas les outils méca-
niques à la pluie ou à des condi-
tions humides.
   De l’eau pénétrant dans un outil 
mécanique augmente le risque 
d’électrocution.
 4)  Ne malmenez pas le cordon. 
N’utilisez jamais le cordon pour 
transporter, pour tirer ou pour 
débrancher l’outil mécanique. 
Gardez le cordon éloigné de la 
chaleur, de l’huile, d’objets aux 
bords coupants ou de pièces en 
mouvement.
   Les cordons endommagés on 
emmêlés augmentent le risque 
d’électrocution.
 5)  Lors du fonctionnement des 
outils mécaniques à l’extérieur, 
utilisez une rallonge adaptée à 
l’utilisation à l’extérieur.
   L’utilisation d’un cordon adapté à 
l’utilisation à l’extérieur réduit les 
risques d’électrocution.
 6)  Si le fonctionnement d’un outil 
mécanique dans un endroit hu-
mide est inévitable, utilisez une 
alimentation électrique pour dis-
positif protégé contre le courant 
résiduel (RC D).
    L’utilisation d’un RCD réduit les ris-
ques d’électrocution.
