2. General Safety Information

Always follow basic safety precautions when using electric tools to reduce the risk of fire, electric shock, and personal injury.

• Work Area Safety: Keep your work area clean and well-lit. Cluttered or dark areas invite accidents.
• Electrical Safety: Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Personal Safety: 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.
• Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. It will do the job better and safer at the rate for which it was designed.
