GENERAL POWER TOOL SAFETY
WARNINGS
WARNING
Read all safety warnings, instructions, illustrations
and specifications provided with this power tool.
Failure to follow all instructions listed below 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
