WARNING
The operation of any
power tool can result in foreign
objects being thrown into your
eyes, which can result in
severe eye damage. Before
beginning power tool operation,
always wear safety goggles or
safety glasses with side shields
and a full-face shield when
needed. We recommend a
Wide Vision Safety Mask for
use over eyeglasses or
standard safety glasses with
side shields. Always use eye

proper accident prevention measures.

GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Read all safety warnings 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.
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
1. Keep work area clean and well lit. Cluttered and dark
areas invite accidents.
2. 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 or fumes.
3. Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control
WORK AREA SAFETY
1. 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.
2. 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.
3. Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
4. 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.
5. 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.
6. If operating a power tool in a damp location is unavoidable,
use a ground-fault circuit interrupter (GFCI) protected
supply. Use of a GFCI reduces the risk of electric shock.
