Keep work area clean and well lit. Cluttered or dark areas invite
accidents.
Do not operate power tools in explosive atmospheres, such as
in the presence of flammable liquids, gases or dust. Power
tools create sparks which may ignite the dust or fumes.
Keep children and bystanders away while operating a power
tool. Distractions can cause you to lose control.
Power tool plugs must match the outlet. Never modify the plug
in any way. Do not use any adapted plugs with earthed(grounded)
power tools. Modified plugs and un-matching outlets will increase
the risk of electric shock.
Avoid body contact with earthed or grounded surfaces, such as
pipes, radiators, ranges and refrigerators. There is an increased
risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep it away from heat, oil, sharp edges
or moving parts.
When operating a power tool outdoors, use an extension cord
suitable for outdoor use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.

Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer
at the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and
off. Any power tool that cannot be controlled with the switch is
dangerous and must be repaired.
Disconnect the plug from the power source and/or the battery
pack from the power tool before making any adjustments,
changing accessories, or storing power tools. Such preventive
safety measures reduce the risk of starting the power tool
accidentally.
Store idle power tools out of the reach of children and do not
allow persons unfamiliar with the power tool or these
instructions to operate the power tool. Power tools are dangerous
in the hands of untrained users.
Keep cutting tools sharp and clean. Properly maintained cutting
tools with sharp cutting edges are less likely to bind and are easier
to control.
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.
Even if you are operating this product in accordance with all the
safety requirements, potential risks of injury and damage remain.
The following dangers can arise:
Health defects resulting from vibration emission if the product is
being used over long periods of time or not adequately managed
and properly maintained.
Injuries and damage to property due to broken cutting attachments
or the sudden impact of hidden objects during use.
Danger of injury and property damage caused by other objects or
due to natural reactions or calamities.

Wear ear protectors. Exposure to noise can cause hearing loss.
Use auxiliary handle 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 or its own cord. Contact with a “live” wire will make
exposed metal parts of the tool “live” and shock the operator.
Use clamps or other practical way to secure and support the
work piece 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 auxiliary 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
reinforcing bar may be hazardous as well. Tighten the auxiliary
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.

Unpack all parts and lay them on flat, stable surface. Remove all
packing materials. Make sure the delivery contents are complete
and free of any damage. If you find that parts are missing or
show damage, do not use the product but contact your dealer.
Using an incomplete or damaged product represents a hazard to
people and property.
Ensure that you have all the accessories and tools needed for
assembly and operation. This also includes suitable personal
protective equipment.
A Rotary hammer is a power tool that can perform heavy-duty
tasks such as hammer-drilling and chiselling hard materials. It is
similar to a hammer drill in that it also pounds the drill bit in and
out while it is spinning. However, rotary hammers use a piston
mechanism instead of a special clutch. This causes them to
deliver a much more powerful hammer blow, making it possible
to drill bigger holes much faster.
For safety reasons it is essential to read the entire instruction
manual before first operation and to observe all the instructions
mentioned in it.
