General Safety Information

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 Safety

1.Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.

2.Do not operate power tools in explosive atmos- pheres, 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

1.Grounded tools must be plugged into an outlet, properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.

2.Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigera- tors. There is an increased risk of electrical shock if your body is grounded.

3.Don’t expose power tools to rain or wet condi- tions. Water entering a power tool will increase the risk of electrical shock.

4.Do not abuse 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 electrical 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 electrical shock.

6.Use only three-wire extension cords which have three-prong grounding plugs and three- pole receptacles which accept the machines plug. Use of other extension cords will not ground the tool and increase the risk of electrical shock.

7.Use proper extension cords. (See chart.) Insuf- ficient conductor size will cause excessive voltage drop, loss of power and overheating.

8.Before using, test the Ground Fault Circuit Interrupter (GFCI) provided with the power cord to insure it is operating correctly. GFCI reduces the risk of electrical shock.

9.Extension cords are not recommended unless they are plugged into a Ground Fault Circuit Interrupter (GFCI) found in circuit boxes or out- let receptacles. The GFCI on the machine power cord will not prevent electrical shock from the extension cords.

10.Keep all electric connections dry and off the ground. Do not touch plug with wet hands. Reduces the risk of electric shock.

Personal Safety

1.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 influ- ence of drugs, alcohol, or medications. A moment of inattention while operating power tools may result in serious personal injury.

2.Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.

3.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.
