WARNING
Explosive fuel vapors.
Can cause severe injury or death.
Useextremecarewhenhandling,storing,
and using fuels.
Explosive fuel vapors can cause severe injury or
death. All fuels are highly explosive in a vapor state.
Use extreme care when handling, storing, and using
fuels. Store fuel in a well-ventilated area away from
spark-producing equipment and out of the reach of
children. Never add fuel to the tank while the engine is
running since spilled fuel may ignite on contact with hot
parts or from ignition spark. Do not smoke or permit
flame or spark to occur near potentialsources of spilled
fuelorfuelvapors. Keepfuellinesand connectionstight
and in good condition—don’t replace flexible fuel lines
with rigid lines. Flexible sections are used to avoid
breakagedueto vibration. Should anyfuelleakage,fuel
accumulation, or electrical sparks be noted, DO NOT
OPERATE GENERATOR SET. Have systemsrepaired
before resuming generator operation.
Explosive fuel vapors can cause severe injury or
death. Additional precautions must be taken when
using the following fuels:
Gasoline—Store gasoline only in approved red
containers clearly marked GASOLINE. Do not store
gasoline in any occupied building.
Propane (LP)—Adequate ventilation is mandatory.
Propane is heavier than air; install gas detectors low in
room. Inspect detectors often.
NOTE
Replacement of the in-line gasoline-type fuel filter must
be of a metal encased type. (Kohler Part No.
228269—1/4 in. inlet or Kohler Part No. 227647—5/16
