WARNING: Explosive Fuel!
LPG is extremely flammable, is heavier than air, and tends to settle in low areas where a spark or flame could
ignite the gas. Do not start or operate this engine in a poorly ventilated area where leaking gas could accumulate
and endanger the safety of persons in the area.
Proper service and repair of LPG fuel systems requires qualified technicians and special equipment.
Many states require special licensing or certification for LPG repair shops and/or technicians. Check state
and local regulations before attempting any adjustment, service, or repair of the LPG system or
components. Faulty repairs by unqualified or underqualified personnel can have very serious
ramifications. The information in this segment is for the exclusive use of qualified LPG service providers.
