WARNING
To avoid serious injury or death:
• Stop the engine and remove the key before
checking the fuel lines and the fuel filter.
• Check the fuel lines periodically. The fuel lines
are subject to wear and aging. Fuel may leak
out onto the running engine, causing a fire.
IMPORTANT :
• When the fuel line is disconnected for
maintenance or repair, plug both ends of the
fuel line with a clean plug of suitable size to
prevent dust and dirt from entering. Take
particular care of the fuel filter in order to avoid
dust and dirt getting into the fuel system.
Entrance of dust and dirt causes malfunction of
the fuel pump.
The fuel line is the rubber product and ages regardless
of service period.
1. Inspect the fuel filter.
2. After inspection of the fuel filter, if the fuel line and
clamps are found damaged or deteriorated, replace
them.
