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 tool by insulated gripping surfaces, when
performing an operation where the cutting accessory
may contact hidden wiring or its own cord. Cutting
accessory contacting a"live" wire may make exposed metal
parts of the power tool "live" and could give the operator an
electric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.

WARNING: We recommend the use of aresidual current
device with aresidual current rating of 30mA orless.
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.
• Risk of personal injury due to flyingparticles.
• Risk of burns due to accessories becoming hot
duringoperation.
• Risk of personal injury due to prolongeduse.
Electrical Safety
The electric motor has been designed for one voltage only.
Always check that the power supply corresponds to the voltage
on the ratingplate.
Your DEWALT tool is double insulated in accordance
with EN60745; therefore no earth wire isrequired.

WARNING: 115 Vunits have to be operated via afail-safe
isolating transformer with an earth screen between the
primary and secondary winding.
If the supply cord is damaged, it must be replaced by
aspecially prepared cord available through the D
EWALT
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: 13A.

extension cable suitable for the power input of this tool (see
Technical Data).The minimum conductor size is 1.5 mm
2
; the
maximum length is 30m.
