GENERAL SAFETY RULES
USA002-2

(For All Tools)

WARNING:

Read and understand all instructions.

Failure to follow all instructions listed below,

may result in electric shock, fire and/or

serious personal injury.

SAVE THESE INSTRUCTIONS

Work Ar ea

1. Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep bystanders, children, and visitors away
while operating a power tool. Distractions can
cause you to lose control.

Electrical Safety

4. Double insulated tools are equipped with a
polarized plug (one blade is wider than the
other.) This plug will fit in a polarized outlet only
one way. If the plug does not fit fully in the outlet,
reverse the plug. If it still does not fit, contact a
qualified electrician to install a polarized outlet.
Do not change the plug in any way. Double insula-
tion eliminates the need for the three wire
grounded power cord and grounded power supply
system.
5. Avoid body contact with grounded surfaces
such as pipes, radiators, ranges and refrigera-
tors. There is an increased risk of electric shock if
your body is grounded.
6. Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the
risk of electric shock.
7. Do not abuse the cord. Never use the cord to
carry the tools or pull the plug from an outlet.
Keep cord away from heat, oil, sharp edges or
moving parts. Replace damaged cords immedi-
ately. Damaged cords increase the risk of electric
shock.
8. When operating a power tool outside, use an
outdoor extension cord marked “W-A” or “W”.
These cords are rated for outdoor use and reduce
the risk of electric shock.

Personal Safety

9. Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use tool while tired or under the influence of
drugs, alcohol, or medication. A moment of inat-
tention while operating power tools may result in
serious personal injury.
10. Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep your hair, cloth-
ing, and gloves away from moving parts. Loose
clothes, jewelry, or long hair can be caught in mov-
ing parts.
11. Avoid accidental starting. Be sure switch is off
before plugging in. Carrying tools with your finger
on the switch or plugging in tools that have the
switch on invites accidents.
