Test the Fuel Select Operation -
Ford Models
The ability to select and switch between
gasoline and LPG fuels as needed is essential to
safe machine operation. A fuel selection can be
made when the engine is running or not.
Switching malfunctions and/or the failure of the
engine to start and run properly in both fuel
modes and through all idle speeds can indicate
fuel system problems that could develop into a
hazardous situation.
Perform this test after checking
the gasoline and LPG fuel levels,
and warming the engine to normal
operating temperature.
1 Move the fuel select switch to gasoline and then
move the engine idle control switch to foot
switch activated high idle (rabbit and foot switch
symbol).
2 Start the engine from the platform controls and
allow it to run at low idle.
3 Press down the foot switch to allow the engine
to run at high idle.
Result: The engine should start promptly and
operate smoothly in low and high idle.
4 Release the foot switch and shut the engine off
by pushing the Emergency Stop button in to the
OFF
position.
5 Move the fuel select switch to LPG.
6 Restart the engine and allow it to run at
low idle.
7 Press down the foot switch to allow the engine
to run at high idle.
Result: The engine should start promptly and
operate smoothly in low and high idle.
The engine may hesitate
momentarily and then continue
to run on the selected fuel if the
fuel source is switched while
the engine is running.
