General Power Tool Safety Warnings
WARNING! Read all safety warnings
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or batteryoperated (cordless) power tool.
1) WORK AREA SAFETY
a) Keep work area clean and well lit.
b) Do not operate power tools in explosive
c) Keep children and bystanders away while
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet.
b) Avoid body contact with earthed or
c) Do not expose power tools to rain or wet
d) Do not abuse the cord. Never use the
and all 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
Cluttered or dark areas invite accidents.

flammable liquids, gases or dust. Power
tools create sparks which may ignite the dust
or fumes.

cause you to lose control.
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.
