ENGLISH
h ) Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpectedsituations.
5) Battery Tool Use and Care
a ) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used with
another batterypack.
b ) Use power tools only with specifically designated
battery packs. Use of any other battery packs may create
a risk of injury andfire.
c ) When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys,
nails, screws or other small metal objects, that can
make a connection from one terminal to another.
Shorting the battery terminals together may cause burns
or afire.
d ) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation orburns.
e ) Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or risk
ofinjury.
f ) Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 130°C may causeexplosion.
g ) Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specified in the instructions. Charging
improperly or at temperatures outside the specified range
may damage the battery and increase the risk offire.
6) 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.
b ) Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized serviceproviders.
Impact Wrench Safety Warnings -
AllOperations
• Hold the power tool by insulated gripping surfaces,
when performing an operation where the fastener may
contact hidden wiring. Fasteners contacting a "live" wire
may make exposed metal parts of the power tool "live" and
could give the operator an electricshock.
• Wear ear protectors during use. Exposure to noise can
cause hearingloss.

WARNING: Impact wrenches are not torque
wrenches. DO NOT use this tool for tightening
fasteners to specified torques. An independent,
calibrated torque measurement device such as a torque
wrench should be used when under tightened or over
tightened fasteners can lead to the failure of thejoint.
Chargers
DeWALT chargers require no adjustment and are designed to be
as easy as possible tooperate.
Electrical Safety
The electric motor has been designed for one voltage only.
Always check that the battery pack voltage corresponds to the
voltage on the rating plate. Also make sure that the voltage of
your charger corresponds to that of yourmains.
i
Your DeWALT charger is double insulated in
accordance with IEC60335; therefore no earth wire
isrequired.
If the supply cord is damaged, it must be replaced only by
DeWALT or an authorised serviceorganisation.
Using an Extension Cable
An extension cord should not be used unless absolutely
necessary. Use an approved extension cable suitable for
the power input of your charger (see Technical Data). The
minimum conductor size is 1mm
2
; the maximum length
is30m.
When using a cable reel, always unwind the cablecompletely.
Important Safety Instructions for All
BatteryChargers
SAVE THESE INSTRUCTIONS: This manual contains important
safety and operating instructions for compatible battery
chargers (refer to TechnicalData).
• Before using charger, read all instructions and cautionary
markings on charger, battery pack, and product using
batterypack.

WARNING: Shock hazard. Do not allow any liquid to get
inside charger. Electric shock mayresult.

WARNING: We recommend the use of a residual current
device with a residual current rating of 30mA orless.

CAUTION: Burn hazard. To reduce the risk of injury,
charge only DeWALT rechargeable batteries. Other
types of batteries may burst causing personal injury
anddamage.

CAUTION: Children should be supervised to ensure that
they do not play with theappliance.
NOTICE: Under certain conditions, with the charger
plugged into the power supply, the exposed charging
contacts inside the charger can be shorted by foreign
material. Foreign materials of a conductive nature such
as, but not limited to, 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 charger before attempting toclean.
