Warning! Remember that gasoline is highly flammable! When working with fuel system components, observe all accepted fire safety measures. Do not smoke! Do not approach the work area with an open flame or unprotected portable appliance! Do not service the system in rooms equipped with natural gas heating devices equipped with a pilot flame (such as water heaters and clothes dryers). Do not forget that gasoline is a carcinogen, i.e., a substance that promotes the development of cancer! Try to avoid fuel coming into contact with exposed areas of the body, use rubber protective gloves, and in case of accidental contact with fuel, wash your hands thoroughly with warm water and soap. Collect spilled fuel immediately and do not store rags soaked in fuel near open flames. Remember that the fuel system of models equipped with fuel injection is constantly under pressure. Before disconnecting fuel lines, relieve residual pressure in the system. Wear safety glasses when servicing fuel system components. Always keep a Class B fire extinguisher on hand!
