2. General Safety Information

Always follow basic safety precautions when using power tools to reduce the risk of fire, electric shock, and personal injury. Familiarize yourself with all warnings and instructions.

2.1 Work Area Safety

  • Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
  • 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.
  • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2.2 Electrical Safety

  • Power tool plugs must match the outlet. Never modify the plug in any way.
  • Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
  • Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

2.3 Personal Safety

  • Always wear eye protection. Use safety glasses, goggles, or a face shield.
  • Wear appropriate personal protective equipment (PPE) such as dust masks, non-skid safety shoes, hard hats, or hearing protection for specific conditions.
  • Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication.
  • Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.
