Important Safety Instructions for All
Battery Chargers
WARNING:Read all safety warnings,
instructions, and cautionary markings for the
battery pack, charger and product. Failure to
follow the warnings and instructions may result
in electric shock, fire and/or seriousinjury.
• DO NOT attempt to charge the battery pack with
any chargers other than a DeWALT charger. DeWALT
chargers and battery packs are specifically designed to
worktogether.
• These chargers are not intended for any uses other
than charging DeWALT rechargeable batteries.
Any other uses may result in risk of fire, electric shock
orelectrocution.
• Do not expose the charger to rain orsnow.
• Pull by the plug rather than the cord when
disconnecting the charger. This will reduce the risk of
damage to the electric plug andcord.
• Make sure that the cord is located so that it will not
be stepped on, tripped over or otherwise subjected
to damage orstress.
• Do not use an extension cord unless it is absolutely
necessary. Use of improper extension cord could result in
risk of fire, electric shock orelectrocution.
• When operating a charger outdoors, always provide
a dry location and use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor use
reduces the risk of electricshock.
• An extension cord must have adequate wire size
(AWG or American Wire Gauge) for safety. The smaller
the gauge number of the wire, the greater the capacity
of the cable, that is, 16 gauge has more capacity than
18gauge. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. When
using more than one extension to make up the total
length, be sure each individual extension contains at
least the minimum wire size. The following table shows
the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier
gauge. The lower the gauge number, the heavier thecord.
hand tools and the like. The US Department of
Transportation Hazardous Material Regulations (HMR)
actually prohibit transporting batteries in commerce
or on airplanes in carry-on baggage UNLESS they
are properly protected from short circuits. So when
transporting individual battery packs, make sure that
the battery terminals are protected and well insulated
from materials that could contact them and cause a
short circuit. NOTE:Li-ion batteries should not be put
in checkedbaggage.

Important Charging Notes
1. Longest life and best performance can be obtained if
the battery pack is charged when the air temperature
is between 65°F – 75°F (18°C–24°C). DO NOT charge
when the battery pack is below +40°F (+4.5°C), or
above +104°F (+40°C). This is important and will
prevent serious damage to the batterypack.
2. The charger and battery pack may become warm to the
touch while charging. This is a normal condition, and
does not indicate a problem.To facilitate the cooling of
the battery pack after use, avoid placing the charger or
battery pack in a warm environment such as in a metal
shed or an uninsulatedtrailer.
3. If the battery pack does not charge properly:
a. Check operation of receptacle by plugging in a lamp
or other appliance;
b. Check to see if receptacle is connected to a light
switch which turns power off when you turn out
the lights;
c. Move the charger and battery pack to a location
where the surrounding air temperature is
approximately 65°F –75°F (18°C– 24°C);
d. If charging problems persist, take the tool, battery
pack and charger to your local servicecenter.
4. The battery pack should be recharged when it fails to
produce sufficient power on jobs which were easily
done previously. DO NOT CONTINUE to use under these
conditions. Follow the charging procedure. You may also
charge a partially used pack whenever you desire with
no adverse effect on the batterypack.
5. Foreign materials of a conductive nature such as, but
not limited to, grinding dust, metal chips, steel wool,
aluminum foil, or any buildup of metallic particles
should be kept away from charger cavities. Always
unplug the charger from the power supply when there
is no battery pack in the cavity. Unplug the charger
before attempting toclean.
6. Do not freeze or immerse the charger in water or any
otherliquid.
Charger Cleaning Instructions

Proper Hand Position (Fig. G)
WARNING:To reduce the risk of serious
personal injury, ALWAYS use proper hand position
as shown.
WARNING:To reduce the risk of serious
personal injury, ALWAYS hold securely in anticipation of
a suddenreaction.
WARNING:Always use proper eye
protection that conforms to ANSI Z87.1 (CAN/CSA
Z94.3) while operating thisappliance.
WARNING:Remove the battery before
making any assembly, adjustments, or changing
accessories. Such preventive safety measures reduce
the risk of starting the TRIMMERaccidentally.
CAUTION:Before you begin trimming, only
use the appropriate type of cuttingline.
CAUTION:Inspect area to be trimmed and
remove any wire, cord, or string-like objects which
could become entangled in the rotating line or spool.
Be particularly careful to avoid any wire which might
be bent outwardly into the path of the appliance, such
as barbs at the base of a chain linkfence.
Proper hand position requires one hand on the primary
handle14 and one hand on the auxiliary handle4.
Switching Trimmer On and Off (Fig. A)
To turn the appliance on, squeeze the lock-off button 2 and
then the variable speed trigger 1 .
To turn the appliance off, release the variable speed trigger
and the lock-offbutton.
WARNING:Never attempt to lock the
trigger in the onposition.
Speed Control Switch (Fig. A)
This string trimmer gives you the choice to operate at a
more efficient speed to extend the runtime for larger jobs, or
accelerate the trimmer speed for high-performancecutting.
To extend runtime, push the speed control switch 3
forward toward the auxillary handle 4 into the "LO"
position. This mode is best for larger projects that require
more time tocomplete.
To accelerate the trimmer, pull the speed control switch
back toward the battery housing 11 into the "HI" position.
This mode is best to cut through heavier growth and for
applications that need higherRPM.
NOTE: When in "HI" mode, runtime will be decreased as
compared to when trimmer is in "LO"mode.

Trimming (Fig. H, I)
With the trimmer on, angle it and swing side to side as
shown in Fig.H.
Maintain a minimum distance of 24" (610 mm) between the
guard and your feet as shown in Fig.I.
WARNING: Keep the rotating string
roughly parallel with the ground (tilted no more than
30 degrees). This trimmer is not an edger. DO NOT
TILT the trimmer so that the string is spinning near
a right angle to the ground. Flying debris can cause
seriousinjury.

Bump Feed Trimmer Line Feed
Your trimmer uses 0.080" (2.0 mm) diameter nylon line.
Cutting line will wear faster and require more feeding if the
cutting is done along sidewalks or other abrasive surfaces or
heavier weeds are beingcut.
As you use the trimmer, the string will get shorter due
to wear. Gently bump the trimmer on the ground while
running at normal speed and the line willfeed.
NOTE: Extending nylon line beyond the 14" (355mm)
swath will negatively affect performance, runtime, and the
life of the trimmer due to potential of damaging motor.
Doing so may void thewarranty.
Helpful Cutting Tips
• Use the tip of the string to do the cutting; do not force
string head into uncutgrass.
• Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may
wear stringrapidly.
• Do not allow spool cap to drag on ground or
othersurfaces.
• In long growth, cut from the top down and do not
exceed 12" (304.8 mm)high.
• Keep trimmer tilted toward the area being cut; this is the
best cuttingarea.
• The trimmer cuts when passing the unit from the left to
right. This will avoid throwing debris at theoperator.
• Avoid trees and shrubs. Tree bark, wood moldings,
siding, and fence posts can easily be damaged by
thestring.
Fig.I
Fig.H
Maintenance Treatments (Fig. J)
• Keep the air intake slots 30 clean to avoid overheating
(Fig.J).
• Your trimmer line can dry out over time. To keep your
line in top condition, store spare line in a plastic, sealable
bag with a tablespoon ofwater.
• Plastic parts may be cleaned by using a mild soap and
a damprag.
• The line cutter on the edge of the guard can dull over
time. It is recommended you periodically touch-up the
sharpness of the blade with afile.

• Protection auditive ANSI S12.6 (S3.19);
• Protection des voies respiratoires
NIOSH/OSHA/MSHA.
AVERTISSEMENT : certaines
poussières contiennent des produits chimiques
reconnus dans l’État de la Californie pour causer le
cancer et des anomalies congénitales ou autres effets
nuisibles sur la reproduction. Certains exemples de ces
produits chimiques sont:
• des composants de fertilisants,
• des composants d’insecticides, d’herbicides et
depesticides,
• l’arsenic et le chrome provenant du bois de
construction traité chimiquement.
Pour réduire votre exposition à ces produits chimiques,
portez un équipement de sécurité approuvé, comme
un masque antipoussière spécialement conçu pour
filtrer les particules microscopiques.
AVERTISSEMENT :cet outil peut
produire et/ou répandre de la poussière susceptible
de causer des dommages sérieux et permanents
au système respiratoire. Utiliser systématiquement
un appareil de protection des voies respiratoires
homologué par le NIOSH ou l’OSHA. Diriger les
particules dans le sens opposé au visage et aucorps..
AVERTISSEMENT : pendant
l’utilisation, porter systématiquement une
protection auditive individuelle adéquate
homologuée ANSI S12.6 (S3.19). Sous certaines
conditions et suivant la durée d’utilisation, le bruit
émanant de ce produit pourrait contribuer à une perte
de l’acuitéauditive.
ATTENTION : après utilisation,
ranger l’outil sur son côté, sur une surface stable,
là où il ne pourra ni faire trébucher ni faire chuter
quelqu’un. Certains outils équipés d’un large bloc-
piles peuvent tenir à la verticale sur celui-ci, mais
manquent alors destabilité.
• Prendre des précautions à proximité des évents,
car ils cachent des pièces mobiles. Vêtements amples,
bijoux ou cheveux longs risquent de rester coincés dans ces
piècesmobiles.
• ÉVITEZ LES DÉMARRAGES ACCIDENTELS – ne pas
transporter avec votre doigt sur la gâchette si la pile
estinstallée.
• DOMMAGES À L’OUTIL – si vous frappez ou si vous vous
emmêlé avec un objet étranger, arrêtez immédiatement
l’outil, retirez la pile, vérifiez les dommages et faites réparer
les dommages avant de tenter de le réutiliser. Ne pas
l’utiliser avec un moyeu ou une bobine brisé.
• NE PAS UTILISER les outils électriques portatifs dans une
atmosphère gazeuse ou explosive. Les moteurs de ces
outils produisent des étincelles et ces étincelles pourraient
enflammer les vapeurs.
• DEMEUREZ VIGILANT – ne pas utiliser cet outil lorsque
vous êtes fatigué, malade ou sous l’influence de l’alcool, de
drogues ou de médicaments.
• NE PAS immerger l’outil dans l’eau ou l’asperger avec
untuyau.
• NE PAS laisser pénétrer tout liquide à l’intérieur. Si l’outil
est mouillé, laissez-le sécher pendant au moins 48 heures.
• NE PAS nettoyer avec une laveuse à pression.
• NE PAS entreposer l’outil sur ou près de fertilisants ou de
produits chimiques.
• AFIN DE RÉDUIRE LE RISQUE DE BLESSURES, ne pas
utiliser l’unité si pliée. L’unité doit être en pleine extension
et le fermoir de la tige fixé avant d’insérer la pile.
• RETIREZ LA PILE AVANT DE PLIER L’UNITÉ. Pliez
complètement l’unité jusqu’à ce qu’elle se verrouille.

Consignes importantes de sécurité
lesblocs-piles
AVERTISSEMENT :lisez toutes
les consignes de sécurité, les instructions et les
symboles d’avertissements du bloc-piles, du
chargeur et du produit. Tout manquement aux
avertissements et instructions pose des risques
de décharges électriques, d’incendie et/ou de
blessures graves.
• Ne pas recharger ou utiliser un bloc-piles en milieu
déflagrant, en présence, par exemple, de poussières,
gaz ou liquides inflammables. Le fait d’insérer ou
retirer un bloc-piles de son chargeur pourrait causer
l’inflammation de poussières ou d’émanations.
• Lorsque non utilisé, garder le bloc-piles éloigné de
petits objets métalliques comme des trombones
attache-feuilles, des pièces de monnaie, des clés, des
clous et vis ou autres pièces qui pourraient court-
circuiter les bornes. Un court-circuit pourrait causer des
brûlures ou unincendie.
• NE JAMAIS forcer l’insertion d’un bloc-piles dans un
chargeur. NE modifier un bloc-piles d’AUCUNE façon
pour le faire rentrer dans un chargeur incompatible,
car il pourrait se briser et causer des dommages
corporels graves. Consulter le tableau en dernière page
de ce manuel pour connaître les compatibilités entre
chargeurs et blocs-piles.
• Recharger les blocs-piles exclusivement dans des
chargeursDeWALT.
• NE PAS éclabousser le bloc-piles ou l’immerger dans l’eau
ou dans tout autreliquide.
• Ne pas entreposer ou utiliser l’appareil et le bloc-
piles en présence de températures ambiantes
pouvant excéder 40°C (104°F) (comme dans des
hangars ou des bâtiments métalliques l’été). Pour
préserver leur durée de vie, entreposer les blocs-piles dans
un endroit frais etsec.
REMARQUE: ne pas mettre un bloc-piles dans un
outil dont la gâchette est verrouillée en position de
marche. Ne jamais bloquer l’interrupteur en position
deMARCHE.
• Ne pas exposer le bloc-piles ou l’outil/l’appareil au
feu ou à une température excessive. L’exposition au
feu ou à une température au-dessus de 130° C (265° F)
pourrait entraîner uneexplosion.
• Ne pas incinérer le bloc-piles même s’il est
sévèrement endommagé ou complètement usagé,
car il pourrait exploser et causer un incendie. Pendant
l’incinération des blocs-piles au lithium-ion, des vapeurs et
matières toxiques sontdégagées.
• En cas de contact du liquide de la pile avec la peau,
rincer immédiatement au savon doux et à l’eau. En
cas de contact oculaire, rincer l’œil ouvert à l’eau claire
une quinzaine de minutes ou jusqu’à ce que l’irritation
cesse. Si des soins médicaux s’avéraient nécessaires, noter
que l’électrolyte de la pile est composé d’un mélange de
carbonates organiques liquides et de sels delithium.
• Le contenu des cellules d’une pile ouverte peut
causer une irritation respiratoire. En cas d’inhalation,
exposer l’individu à l’air libre. Si les symptômes persistent,
consulter unmédecin.
AVERTISSEMENT :risques de
brûlure. Le liquide de la pile peut s’enflammer s’il est
exposé à des étincelles ou à uneflamme.
AVERTISSEMENT :risques
d’incendie. Ne jamais tenter d’ouvrir le bloc-piles
pour quelque raison que ce soit. Si le boîtier du
bloc-piles est fissuré ou endommagé, ne pas l’insérer
dans un chargeur. Ne pas écraser, laisser tomber, ou
endommager les blocs-piles. Ne pas utiliser un bloc-
piles ou un chargeur qui a reçu un choc violent, ou si
l’appareil est tombé, a été écrasé ou endommagé de
quelque façon que ce soit (p. ex. percé par un clou,
frappé d’un coup de marteau, piétiné). Les blocs-piles
endommagés doivent être renvoyés à un centre de
réparation pour y êtrerecyclés.

poche, une boîte à outils ou un tiroir, etc. contenant
des objets tels que clous, vis, clés, etc. Le fait de
transporter des blocs-piles comporte des risques
d’incendie, car les bornes des piles pourraient
entrer, par inadvertance, en contact avec des
objets conducteurs, tels que: clés, pièces de
monnaie, outils ou autres. La réglementation sur les
produits dangereux (Hazardous Material Regulations)
du département américain des transports interdit, en
fait, le transport des blocs-piles dans les commerces
ou dans les avions dans les bagages de cabine, À
MOINS qu’ils ne soient correctement protégés de
tout court-circuit. Aussi lors du transport individuel
de blocs-piles, s’assurer que leurs bornes sont bien
protégées et isolées de tout matériau pouvant entrer
en contact avec elles et provoquer un court-circuit.
REMARQUE: il ne faut pas laisser de piles au li-ion
dans les bagagesenregistrés.
Recommandations de stockage
1. Le lieu idéal de rangement est un lieu frais et sec,
à l’abri de toute lumière solaire directe et de toute
températureexcessive.
2. Pour un stockage prolongé, il est recommandé
d’entreposer le bloc-piles pleinement chargé dans
un lieu frais et sec, hors du chargeur pour optimiser
lesrésultats.
REMARQUE: les blocs-piles ne devraient pas être
entreposés complètement déchargés. Il sera nécessaire de
recharger le bloc-piles avantréutilisation.
Instructions d’entretien du blocs-pile
Éliminer toute saleté ou graisse de la surface externe
du blocs-pile à l’aide d’un chiffon ou d’une brosse
non métallique douce. N’utiliser ni eau ni aucun
nettoyantliquide.
Témoin de Charge du Bloc-Piles
Certains blocs-piles DeWALT possèdent un témoin de
charge qui consiste en trois voyants Del indiquant le niveau
de charge dubloc-piles.
Le témoin de charge indique approximativement le niveau
de charge restant dans le bloc-piles en fonction des
voyantssuivants:
Chargé de 75 à 100%
Chargé de 51 à 74%
Chargé de < 50%
Le bloc-piles doit être rechargé
Pour activer le témoin de charge, maintenez appuyé le
bouton du témoin de charge. Une combinaison des trois
voyants Del s’allumera indiquant le niveau de charge.
Lorsque le niveau de charge du bloc-pile atteint la limite
minimale d’utilisation, le témoin de charge reste éteint et le
bloc-piles doit êtrerechargé.
REMARQUE: le témoin de charge ne fait qu’indiquer
le niveau de charge du bloc-piles. Il ne donne aucune
indication quant au fonctionnement de l’outil. Son
propre fonctionnement pourra aussi varier en fonction
des composants produit, de la température et de
l’applicationd’utilisation.
Pour plus d’informations quant au témoin
de charge du bloc-piles, veuillez appeler le

Le sceau SRPRCMD (Société de recyclage
des piles rechargeables du Canada)
apposé sur une pile au nickel-cadmium,
à hydrure métallique de nickel ou au lithium-ion (ou un
bloc-piles) indique que les coûts de recyclage de ces
derniers en fin d’utilisation ont déjà été réglés par DeWALT.
Dans certaines régions, la mise au rebut ou aux ordures
municipales des piles au nickel-cadmium, à l’hydrure
métallique de nickel ou au lithium-ion, est illégale; le
programme de l’Appel à RecyclerMD constitue donc une
solution pratique etécologique.
Appel à Recycler Canada, Inc., en collaboration avec
DeWALT et d’autres utilisateurs de piles, a mis sur pied de
programme aux États-Unis et au Canada pour faciliter la
collecte des piles au nickel-cadmium, à l’hydrure métallique
de nickel ou au lithium-ion usagées. Aidez-nous à protéger
l’environnement et à conserver nos ressources naturelles
en renvoyant les piles au nickel-cadmium, à l’hydrure
métallique de nickel ou au lithium-ion usagées à un centre
de réparation autorisé DeWALT ou chez votre détaillant afin
qu’elles y soient recyclées. On peut en outre se renseigner
auprès d’un centre de recyclage local pour connaître
d’autres sites lesacceptant. SRPRCMD est une marque
