General
safety rules
WARNING - To reduce the risk of injury,
user must read instruction manual!
WARNING! Read all safety warnings and
all instructions. Failure to follow the warn-
ings and instructions may result in electric
shock, fire and / or serious injury.
Save all warnings and instructions for future refer-
ence.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operat-
ed (cordless) power tool�
Work area safety
• Keep work area clean and well lit. Cluttered or
dark areas invite accidents�
• Do not operate power tools in explosive atmos-
pheres, such as in the presence of flammable liq-
uids, gases or dust. Power tools create sparks which
may ignite the dust or fumes�
• Keep children and bystanders away while oper-
ating a power tool. Distractions can cause you to lose
control�
Electrical safety
• 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. Un-
modified plugs and matching outlets will reduce 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 condi-
tions. 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 cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
the risk of electric shock�
• 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 elec-
tric shock�
• If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk
of electric shock� NOTE! The term "residual current
device (RCD)" may be replaced by the term "ground
fault circuit interrupter (GFCI)" or "earth leakage circuit
breaker (ELCB)"�
• Warning! Never touch the exposed metal sur-
faces on gearbox, shield, and so on because touch-
ing metal surfaces will be interfered with the elec-
tromagnetic wave, thus causing potential injury or
accidents�
Personal safety
• 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�
• 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�
• Prevent unintentional starting. Ensure the
switch is in the off-position before connecting to
power source and / or battery pack, picking up or
carrying the tool . Carrying power tools with your fin -
ger on the switch or energising power tools that have
the switch on invites accidents�
• Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left at-
tached to a rotating part of the power tool may result
in personal injury�
• Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of the
power tool in unexpected situations�
• 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�
• If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of dust
collection can reduce dust-related hazards�
• Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles � A careless action can cause
severe injury within a fraction of a second�
• Warning! Power tools can produces an electro-
magnetic field during operation. This field may under
some circumstances interfere with active or passive
medical implants� To reduce the risk of serious or
fatal injury, we recommend persons with medical im-
plants to consult their physician and the medical im-
plant manufacturer before operating this power tool�
Power tool use and care
• The persons with lowered psychophysical or men-
tal aptitudes as well as children can not operate the
