5.1 General Power Tool Safety Warnings
a)
WARNING
Read all safety warnings and instructions. Failure
to follow 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.
5.1.1 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 atmo-
spheres, 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 operat-
ing a power tool. Distractions can cause you to lose
control.
5.1.2 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. Un-
modified 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 condi-
tions. 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.
5.1.3 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 and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
