WARNING
Fuel is flammable and explosive. Ensure the key switch is off and the lanyard is positioned
so that the engine cannot start. Do not smoke or allow sources of spark or open flame in
the area while servicing. Keep the work area well ventilated and avoid prolonged
exposure to vapors. Always check for leaks before attempting to start the engine and
wipe up any spilled fuel immediately.
!
CAUTION
Failure to release pressure from the fuel system will result in fuel spraying out, which can
cause a fire or explosion. Allow the engine to cool completely and release all fuel pressure
before servicing any part of the fuel system. Always protect eyes and skin from
pressurized fuel and vapors.
