a vapor state. Use extreme care when handling and
storing fuels. Store fuel in a well-ventilated area away

children. Never add fuel to the tank while the engine is
runningsincespilledfuel may ignite on contact with hot
parts or from ignition spark. Do not smoke or permit
flame or spark to occur near sources of spilled fuel or

rigid lines. Use flexible sections to avoid breakage

operation
Explosive fuel vapors can cause severe injury or
death. Take additional precautions when using the
following fuels:
Gasoline—Store gasoline only in approved red
containers clearly marked GASOLINE.
Propane (LP)—Adequate ventilation is mandatory.
Propane is heavier than air; install propane gas
detectors low in room. Inspect detectors often.
Natural Gas—Adequate ventilation is mandatory.
Natural gas rises; install natural gas detectors high in
room. Inspect detectors often.
Fuel tanks. Explosivefuel vaporscancausesevere
injury or death. Gasoline and other volatile fuels
stored in day tanks or subbasefuel tanks cancausean
explosion. Store only diesel fuel in tanks.
Draining fuel system. Explosive fuel vapors can
cause severe injury or death. Spilled fuel can cause
an explosion. Use a container to catch fuel when
draining fuel system. Wipe up all spilled fuel after
draining system.
LP gas fuel leaks. Explosive fuel vapors can cause
severe injury or death. Fuel leakage can cause an
explosion. Check LP vapor gas or natural gas fuel
systemforleakageusingasoap-watersolutionwithfuel
system test pressurized to 6-8 ounces per square inch
(10-14 inches water column). Do not use soap
containing ammonia or chlorine in test solutions, since
the soap will not bubble and will not allow an accurate
leakage test.
LP liquid withdrawal fuel leaks. Explosive fuel
vapors can cause severe injury or death. Fuel
leakage can cause an explosion. Check LP liquid
withdrawal gas fuel system for leakage using a
soap-water solution with fuel system test pressurized
not less than 90 psi (621 kPa). Do not use soap
containing ammonia or chlorine in test solutions, since
the soap will not bubble and will not allow an accurate
leakage test.
