General Power Tool Safety Warnings
WARNING：
Read all safety warnings and all instructions. Failure to follow all warnings and instructions
may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refer to your mains operated (corded) power tool or battery
operated (cordless) power tool.
1) Work area safety
a)Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause
you to lose control.

4
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use
any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
e) 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.
f) If operating a power tools in a damp location is unavoidable, use a residual current
device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a power
tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol
or medication. A moment of inattention while operating power tools may result in serious
personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting
to power source, picking up or carrying the tool. Carrying power tools with your finger on
the switch or plugging in power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key
left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in
moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of these devices can reduce dust related
hazards.

4) Power tool use and care
a) 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.
b) 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.
c) Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures reduce the risk of starting
the power tool accidentally.
d) 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.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of
parts and any other condition that may affect the power tool’s operation. If damaged, have
the power tool repaired before use. Many accidents are caused by poorly maintained power
tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control;
g) Use the power tool, accessories and tool bits etc., in accordance with these instructions,
taking into account the working conditions and the work to be performed. Use of the power
tool for operations different from intended could result in a hazardous situation.
5) 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.
Special requirements for rotary hammer
1. Wear ear protectors. Exposure to noise can cause hearing loss.
2. Use auxiliary handles, if supplied with the tool. Loss of control can cause personal injury.
3. 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.
4. Wear a dust mask. Do not inhale the harmful dusts generated in drilling or chiseling operation.
The dust can endanger the health of yourself and bystanders.
5. Before beginning work, check the working area (e.g. with a metal detector) to ensure that no
concealed electric cables or gas and water pipes are present. Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line
causes property damage or may cause an electric shock.
6. If the supply cord of this power tool is damaged, it must be replaced by a specially prepared cord
available through the service organization.
7. Do not touch the bit during or immediately after operation. The bit becomes very hot during
operation and could cause serious burns.
8. Do not use the power tool with a damaged cord. Do not touch the damaged cord and pill the
plug from the outlet when the cord is damaged while working. Damaged cords increase the risk
of an electric shock.
Warning: Reduce the working time to avoid risks related with too much vibration.
