General Power Tool Safety Warnings
WARNING
：
Read all safety warnings and all instructions.
Failure
to follow all the 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 refers 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 or 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.
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 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.
g)Recommendation that the tool always be supplied via a residual
current device with a rated residual current of 30 mA or less.
h)Always check that the power supply corresponds to the voltage on the
rating plate.
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
