minimize overspray and accumulation on the Air Compressor. Use a face mask/
respirator when spraying, and spray in a well ventilated area to prevent health
and fire hazards. Do not smoke when spraying paint, insecticides, or other
flammable substances. When spraying or cleaning with solvents or toxic
chemicals, follow the instructions provided by the chemical manufacturer.
