Q-16
Test the Fuel Select Operation -
Gasoline/LPG Models
Genie specifications require that this procedure be
performed quarterly.
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.
Note: Perform this test after checking the gasoline
and LPG fuel levels, and warming the engine to
normal operating temperature.
1 At the platform controls, 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 in the red Emergency Stop
button in to the off position.
