Reducing of Dust Exposure
Before starting work, check the hazard class of the dust that will
be produced when working.

WARNING: Dust can be harmful to health. Touching or
breathing of some dust created during the work process
by using a power tool and other construction activities
contains chemicals, mineral or particles known to
cause respiratory infections, allergic reactions, cancer,
birth defects or other reproductive harm of the user or
bystanders.
• Such dusts can be generated, for example, when working ‑
on hardwoods such as beech or oak, lead based paint, on
concrete, masonry or stones containing quartz.
• Material containing asbestos may be handled only by
specialists.
• Observe the relevant regulations in your country for the
materials to be worked on.
• Use a dust extractor or extraction system with an officially
approved protection class in compliance with the locally
applicable dust protection regulations and suitable for the
material to be worked on.
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. It should be done by an
authorized specialist. Improperly reconditioned bits 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.
• Be certain that the material being drilled does not
conceal electric or gas service and that their locations
have been verified with the utility companies.
• Slightly worn chisels can be resharpened by grinding.
• Do not overheat the bit (discoloration) while grinding
a new edge. Badly worn chisels require reforging. Do not
reharden and temper the chisel.
• 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.
Additional Safety Instructions for Hammers
• 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
Safety Instructions When Using Long
DrillBits with Rotary Hammers
• Always start drilling at low speed and with the bit tip
in contact with the workpiece. At higher speeds, the bit is
likely to bend if allowed to rotate freely without contacting the
workpiece, resulting in personalinjury.
• Apply pressure only in direct line with the bit and do not
apply excessive pressure. Bits can bend causing breakage or
loss of control, resulting in personalinjury.
Hammer Safety Warnings
• Wear ear protectors. Exposure to noise can cause
hearingloss.
• Use auxiliary handle(s) if supplied with the tool. Loss of
control can cause personalinjury.
• Hold the 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.
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 authorised serviceproviders.
