GENERAL SAFETY RULES

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 Area

1. Keep your work area clean and well lit.

Cluttered benches 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 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

1. Double Insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in 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 Insulation      eliminates the need for the three wire grounded power cord and grounded power supply system.

2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators.

There is an increased risk of electric shock if your body is grounded.

3. Don't 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 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 immediately.

Damaged cords increase the risk of electric shock.

5. 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.
