GENERAL SAFETY INSTRUCTIONS
Warning: Read all instructions. Failure to follow all instructions listed elow may result in
electric shock, fire and/or serious personal injury. The term “power tool” in all of the
warnings listed elow refers to your mains-operated (corded) power tool or
attery-operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) WORK AREA
a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
) Do not operate power tools in explosive atmosphere, such as in the presence of
flamma le liquids, gases, or dust. Power tools create sparks which may ignite the dust
or fumes.
c) Keep children and ystanders 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.
) Avoid ody contact with earthed or grounded surfaces such as pipes, radiators, ranges,
and refrigerators. There is an increased risk of electric shock if your ody 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 a use 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 suita le for outdoor use.
Use of a cord suita le 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.
