Failure to follow all instructions listed below may result in electric shock, fire, and/or serious personal injury. SAVE THESE INSTRUCTIONS! Work Area Safety. Keep 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 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. 4. Do not let visitors contact the tool or extension cord. Such preventative measures reduce the risk of injury. Electrical Safety. 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. Grounding pin Cover of grounded outlet box Grounding pin 2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electrical 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 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. Connect the tool to an AC power supply that matches the name plate specifications. Incorrect voltage supply can cause electrical shock or burns. 7. Use only three-wire extension cords which have three-prong grounding plugs and three-pole receptacles which accept the machine plug. Use of other extension cords will not ground the tool and increase the risk of electrical shock. 8. Use proper extension cords. (See chart.) Insufficient conductor size will cause excessive voltage drop, loss of power and overheating.
