Keep work area clean and well lit. Cluttered ordark areas invite accidents.2. Do not operate power tools in explosive atmo-spheres, such as in the presence of flammableliquids, gases or dust. Power tools create sparkswhich may ignite the dust or fumes.3. Keep children and bystanders away whileoperating a power tool. Distractions can causeyou to lose control.Electrical Safety1. Power tool plugs must match the outlet. Nevermodify the plug in any way. Do not use anyadapter plugs with earthed (grounded) powertools. Unmodified plugs and matching outlets willreduce risk of electric shock.2. Avoid body contact with earthed or groundedsurfaces, such as pipes, radiators, ranges andrefrigerators. There is an increased risk of elec-tric shock if your body is earthed or grounded.3. Do not expose power tools to rain or wet con-ditions. Water entering a power tool will increasethe risk of electric shock.4. Do not abuse the cord. Never use the cord forcarrying, pulling or unplugging the power tool.Keep cord away from heat, oil, sharp edgesor moving parts. Damaged or entangled cordsincrease the risk of electric shock.5. When operating a power tool outdoors, use anextension cord suitable for outdoor use. Use of a cordsuitable for outdoor use reduces the risk of electric shock.6. If operating a power tool in a damp location isunavoidable, use a ground fault circuit inter-rupter (GFCI) protected supply. Use of a GFCIreduces the risk of electric shock.Personal Safety1. Stay alert, watch what you are doing and usecommon sense when operating a power tool.Do not use a power tool while you are tired orunder the influence of drugs, alcohol or med-ication.
