WARNING
Propane is extremely fl ammable and is heavier than air and
tends to settle in low areas where a spark or fl ame could
ignite gas. Do not start or operate this engine in a poorly
ventilated area where leaking gas could accumulate and
endanger safety of persons in area.
To ensure personal safety, installation and repair of propane
fuel supply systems must be performed only by qualifi ed
propane system technicians. Improperly installed and
maintained propane equipment could cause fuel supply
system or other components to malfunction, causing gas
leaks.
Observe federal, state and local laws governing propane
fuel, storage, and systems.
Explosive Fuel can cause fi res and severe
burns.
If a gaseous odor is detected, ventilate area
and contact an authorized service technician.
