What are the important safety warnings and precautions for operating this pressure washer?

Never direct the water stream toward people, animals, or electrical devices as the high-pressure jet can cause serious injury. Always wear eye protection with side shields marked to comply with ANSI Z87.1, and hold the trigger handle securely with both hands as reaction forces may cause it to move when the trigger is pulled. Never use extension cords; plug directly into a receptacle. Do not operate while under the influence of drugs, alcohol, or medication, and keep children and pets away from the work area. Only use cold water and approved pressure washer detergents—never use acids, alkalines, bleaches, solvents, or flammable materials. (Pages 3-5, 16, 18)
