Gasoline is highly flammable and explo-
sive. Failure to check for and repair any
fuel leakage could result in a fire or explo-
sion. A fire or explosion can cause severe
injury or death. Shut the engine off. Do not
smoke. Avoid spilling gasoline.
Fuel in the fuel lines is pressurized.
Fuel can spray out and cause injury or a
fire hazard if a fuel line is disconnected.
Do not run the engine with a fuel line dis-
connected.
Check the fuel system for leaks, cracks, and
malfunctions. If any problem is found, consult
a Yamaha dealer.
Check:

Fuel tank filler cap and seal for damage.

Fuel in fuel tank for water and dirt.

Fuel tank for damage, cracks, and leakage.

Fuel hoses and joints for damage, cracks,
and leakage.
