LPG Engines
LPG Fuel Recommendations
Liquefied Petroleum Gas (LPG) from an appropriate LP
fuel tank (supplied separately) is required to operate
this engine.
a
WARNING: Pressurized LPG!
Fuel tanks are filled under pressure and should be
handled with care. To prevent tank damage which could
endanger the safety of the operator or persons in the
area, do not drop or drag tanks on any surface. Use a
hand truck when moving, or tilt the tank on its footring in
a position slightly off vertical and roll it.
Avoid personal contact with LPG fuel to prevent
frostbite. See a physician if frostbite occurs.
a
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.
LPG fuel consists primarily of propane, although the fuel
supplier may sometimes mix other gases with propane.
Fuel tanks must be filled only by persons qualified in the
handling of LPG. Tanks are filled by weight and should
not be overfilled (never to more than 80 percent of total
capacity). An air space must be present in the tank to
allow fuel to expand.
Tanks must be removed from equipment before filling.
Dual-Fuel Engines
Dual-fuel engines are designed to operate on either
LPG or gasoline. For LPG operation, the above
information and warnings apply. For gasoline operation,
the following information and warnings apply.
Fuel Recommendations
a
WARNING: Explosive Fuel!
Gasoline is extremely flammable and its vapors can
explode if ignited. Store gasoline only in approved
containers, in well ventilated, unoccupied buildings,
a way from sparks or flames. Do not fill the fuel tank
while the engine is hot or running, since spilled fuel
could ignite if it comes in contact with hot parts or
sparks from ignition. Do not start the engine near
spilled fuel. Never use gasoline as a cleaning agent.
General Recommendations
Purchase gasoline in small quantities and store in
clean, approved containers. A container with a capacity
of 2 gallons or less with a pouring spout is
recommended. Such a container is easier to handle
and helps eliminate spillage during refueling.
Do not use gasoline left over from previous season,
to minimize gum deposits in your fuel system and to
insure easy starting.
Do not add oil to the gasoline.
Do not overfill the fuel tank. Leave room for the fuel to
expand.
Fuel Type
For best results, use only clean, fresh, unleaded
gasoline with a pump sticker octane rating of 87 or
higher. In countries using the Research method, it
should be 90 octane minimum.
Unleaded gasoline is recommended as it leaves less
combustion chamber deposits. Leaded gasoline may be
used in areas where unleaded is not available and
exhaust emissions are not regulated. Be aware
however, that the cylinder heads may require more
frequent se nice.
Gasoline/Alcohol blends
Gasohol (up to 10% ethyl alcohol, 90% unleaded
gasoline by volume) is approved as a fuel for Kohler
engines. Other gasoline/alcohol blends are not
approved.
Gasoline/Ether blends
Methyl Tertiary Butyl Ether (MTBE) and unleaded
gasoline blends (up to a maximum of 15% MTBE by
volume) are approved as a fuel for Kohler engines.
Other gasoline/ether blends are not approved.
