NOTE emphasizes essential information.
SAFETY
GENERAL SAFETY RULES
WARNING:
Read all instructions
Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
The term “power tool” in all of the warnings listed below refers to your mains-operated (corded) power tool
or battery-operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
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 of 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.
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.
3
English
