ENGLISH
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.
Additional Safety Instructions for Rotary
Hammers
• Wear ear protectors. Exposure to noise can cause hearingloss.
• Use auxiliary handles supplied with the tool. Loss of control
can cause personalinjury.
• Hold power tools by insulated gripping surfaces when
performing an operation where the cutting tool may contact
hidden wiring. Contact with a “live” wire will make exposed
metal parts of the tool “live” and could give the operator an
electricalshock.
• Use clamps or other practical way to secure and support the
workpiece to a stable platform. Holding the work by hand or
against your body is unstable and may lead to loss ofcontrol.
• Wear safety goggles or other eye protection. Hammering
operations cause chips to fly. Flying particles can cause
permanent eye damage. Wear a dust mask or respirator
for applications that generate dust. Ear protection may be
required for mostapplications.
• Keep a firm grip on the tool at all times. Do not attempt
to operate this tool without holding it with both hands. It
is recommended that the side handle be used at all times.
Operating this tool with one hand will result in loss of control.
Breaking through or encountering hard materials such as
re-bar may be hazardous as well. Tighten the side handle
securely beforeuse.
• Do not operate this tool for long periods of time. Vibration
caused by hammer action may be harmful to your hands and
arms. Use gloves to provide extra cushion and limit exposure
by taking frequent restperiods.
• Do not recondition bits yourself. Chisel reconditioning should
be done by an authorized specialist. Improperly reconditioned
chisels could causeinjury.
• Wear gloves when operating tool or changing bits. Accessible
metal parts on the tool and bits may get extremely hot
during operation. Small bits of broken material may damage
barehands.
• Never lay the tool down until the bit has come to a complete
stop. Moving bits could causeinjury.
• Do not strike jammed bits with a hammer to dislodge them.
Fragments of metal or material chips could dislodge and
causeinjury.
• Slightly worn chisels can be resharpened bygrinding.
• Keep the power cord away from the rotating bit. Do not
wrap the cord around any part of your body. An electric cord
wrapped around a spinning bit may cause personal injury and
loss ofcontrol.
Residual Risks
The following risks are inherent to the use of rotary hammers:
• Injuries caused by touching the rotating parts or hot parts of
thetool.
In spite of the application of the relevant safety regulations
and the implementation of safety devices, certain residual risks
cannot be avoided. These are:
• Impairment ofhearing.
• Risk of squeezing fingers when changing theaccessory.
• Health hazards caused by breathing dust developed when
working in concrete and/ormasonry.
SAVE THESE INSTRUCTIONS
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.
Your
DeWALT
charger is double insulated in
accordance with EN60335; therefore no earth wire
isrequired.
If the supply cord is damaged, it must be replaced by a
specially prepared cord available through the
DeWALT
serviceorganisation.
Mains Plug Replacement
(U.K. & Ireland Only)
If a new mains plug needs to be fitted:
• Safely dispose of the oldplug.
• Connect the brown lead to the live terminal in theplug.
• Connect the blue lead to the neutralterminal.

WARNING: No connection is to be made to the
earthterminal.
Follow the fitting instructions supplied with good quality plugs.
Recommended fuse: 3A.
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.
