4.13 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 cyl-
inders 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 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 STOP-
PING THE ENGINE. EXTREME CARE MUST BE TAKEN AND THE FOLLOWING INSTRUC-
TIONS MUST BE FOLLOWED.
