WARNING
Performing service or maintenance without first disconnecting the battery can cause product damage, personal injury, or
death
due to fire, explosion, electrical shock, or unexpected engine starting. Always disconnect the battery cables from the
battery before maintaining, servicing, installing, or removing engine or drive components.
!
WARNING
Fuel is flammable and explosive. Ensure that 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.
1. For electric start models, disconnect the battery cables from the battery. Always disconnect the negative battery cable first,
and then the positive.
2.
Install a fuel pressure gauge to the fuel rail service port and release the fuel into an appropriate container.
