FUEL IS EXTREMELY FLAMMABLE AND CAN CAUSE FIRES AND EXPLOSIONS
Carry out refueling away from flames or sparks.
Stop the engine when refueling.
After refueling, tighten the gas cap securely and wipe up any spilled fuel.
The specific gravity of LPG is heavier than air, so it is easy for the vapors to accumulate in low places
(holes, road surface depressions, etc.). This can create a fire or explosion hazard. Be extremely careful!
Engine starting aids are highly flammable and may cause an explosion.
Do not use starting aids to start the engine.
Accidents involving fuel systems are always dangerous and can cause fire and explosion, serious injury,
death and property damage. Keep the following points in mind when working with fuel systems.
Read, understand and remember relevant information in the NATIONAL FIRE PROTECTION AGENCY
(NFPA) standard for fuel in use. Do this BEFORE working on any fuel system.
Ensure you are wearing proper personal protective equipment.
Check for fuel leaks before you begin work on any fuel system. On LPG systems, DO NOT work on the
system if the fuel storage container is filled with fuel past the 80% liquid level.
Ensure there are NO SOURCES OF IGNITION nearby before beginning work.
Be sure your work area is adequately ventilated.
Disconnect the battery before working on the fuel system.
LPG is heavier than air and will sink to the lowest area possible. Avoid areas near floor drains or
lubrication pits where escaped fuel may collect.
LPG is stored under high pressure. Ensure the LPG fuel storage container valve is turned OFF (closed),
and pressure is released from the lines, before working on system.
Store all LPG cylinders OUTDOORS in a secured area and safe from any vehicle traffic.
NEVER WELD ON AN LPG PRESSURE VESSEL, STORAGE TANK OR CYLINDER.
LPG fuel tanks mounted horizontally MUST BE positioned properly. See "MAINTENANCE" chapter.
Always utilize a UL-listed LPG tank.
