4.15 DUAL FUEL SYSTEM (GAS ENGINE ONLY)
Description
The dual fuel system enables the standard gasoline engine
to run on either gasoline or LP gas. The system includes
pressurized cylinders mounted on the frame, and the valves
and switches needed to switch the fuel supply from gasoline
to LP gas or from LP gas to gasoline.
A two position, FUEL SELECT toggle switch at the platform
control station supplies electrical power to open the gasoline
shut-off solenoid and close the LP gas shut off solenoid
when positioned to the GASOLINE position. This switch also
allows electrical power to open the LP gas shut-off solenoid
and close the gasoline shut-off solenoid when positioned to
the LP position.
IT IS POSSIBLE TO SWITCH FROM ONE FUEL SOURCE TO THE OTHER
WITHOUT STOPPING THE ENGINE. EXTREME CARE MUST BE TAKEN
