Test the Fuel Select Operation -

Genie requires that this procedure be performed
every 250 hours or quarterly, whichever comes
first.
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 whether 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.
Note: Be sure that the valve on the LPG tank is in
the position.
