Explosive Fuel

burns.
If a gaseous 

odor is detected, 

ventilate area 

and contact 

an authorized 

service 

technician.

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.

Avoid inhaling 

exhaust fumes. 

Never run 

engine indoors

spaces.

Engine exhaust gases 

contain poisonous carbon 

monoxide. Carbon 

monoxide is odorless, 

colorless, and can cause 

death if inhaled.

Fluids can 

puncture skin 

and cause 

severe injury or 

death.
Do not work
