Note: In some areas, local law requires using resistor
spark plug to suppress ignition signals. If this engine
was originally equipped with resistor spark plug, use
same type for replacement.
Fuel Filter
• Drain fuel tank or close fuel shut-off
valve before replacing fuel filter.
Otherwise, fuel can leak out creating a
fire/explosion hazard.
WARNING
When replacing fuel filter, ensure clamps are tight and
fuel flows in the same direction as the arrow marked
FLOW.
Muffler/Fuel System
WARNING
• Replacement parts for muffler and fuel system
(cap, hoses, tanks, filters, etc.) must be the
same and installed in the same position as
original parts, otherwise fire can occur.
