5.7 Fuel Pressure and Mixture Adjust-
ments
WARNING
Gaseous fuels are flammable and explosive and
can cause severe personal injury or death. Do not
allow cigarettes, flame, pilot lights, arcing
switches or equipment in area or areas sharing
ventilation. Keep a type ABC fire extinguisher
nearby.
WARNING
Natural gas is lighter than air, and will tend to
gather under hoods. LPG is heavier than air, and
will tend to gather in sumps or low areas. NFPA
Standard No. 58 requires all persons handling
and operating LPG to be trained in proper han-
dling and operating procedures.
WARNING
Do not attempt to correct power by adjusting fuel
system before determining that the engine and
the ignition system are functioning properly.
Especially check air cleaner restriction due to dirt
accumulation.
IMPORTANT: Read the warranty statement provided
with the genset for US Environmental Protection
Agency (EPA) restrictions on servicing specific com-
ponents.
