Explosion and Fire. Fuel and vapors are extremely
flammable and explosive. Add fuel in a well
ventilated area. Keep fire and spark away. Failure
to do so will result in death or serious injury.

high-pressure fluid streams that can pierce
skin. Fluid injection could result in death or
serious injury.
Fuel requirements are as follows:
• Clean, fresh, unleaded gasoline.
• Minimum rating of 87 octane/87 AKI (91
RON).
• Up to 10% ethanol (gasohol) is acceptable

ommended).
• DO NOT use E85.
• DO NOT use a gas oil mix.
• DO NOT modify engine to run on alternate
fuels. Stabilize fuel prior to storage.

Figure 2-13. Add Recommended Fuel
NOTE: Allow spilled fuel to evaporate before
starting unit.
IMPORTANT NOTE: It is important to pre-
vent gum deposits from forming in fuel
system parts such as the carburetor, fuel
hose or tank during storage. Alcohol-
blended fuels (called gasohol, ethanol or
methanol) can attract moisture, which
leads to separation and formation of acids
during storage. Acidic gas can damage the
(000105)
fuel system of an engine while in storage.
To avoid engine problems, the fuel system
should be emptied before storage of 30
days or longer. See the
Never use engine or carburetor cleaner
products in the fuel tank as permanent
damage may occur.
Fuel - LP Requirements
Risk of burns. Contact with liquid contents of cylinder
will cause freeze burns to the skin. If liquid contents
contacts skin or eyes, seek immediate medical
attention.
Personal injury. Keep out of reach of children.
Failure to do so could result in death or serious injury.
NOTE: LP vapor 1st stage regulator inlet pres-
sure is approximately 30 psi at 0 °F, and 218
psi at 100 °F.
Use only standard 20 or 30 pound capacity LP
cylinders with Type 1, right hand Acme
threads with this generator. Verify qualification
date on cylinder has not expired. Do not use
rusted or damaged cylinders.
All new cylinders must be purged of air and
moisture prior to filling. Used cylinders that
have not been plugged or kept closed must
also be purged.
The purging process should be done by the
propane gas supplier. (Cylinders from an
exchange supplier should have been purged
and properly filled by supplier).
