Changing from Gasoline to LP Gas
IT IS POSSIBLE TO SWITCH FROM ONE FUEL SOURCE TO THE
OTHER WITHOUT ALLOWING THE ENGINE TO STOP. EXTREME
CARE MUST BE TAKEN AND THE FOLLOWING INSTRUCTIONS
MUST BE FOLLOWED.
1. Start the engine from the ground control station.
2. Open the hand valve on the LP gas supply tank by
turning counterclockwise.
BE SURE ALL GASOLINE IS EXHAUSTED BEFORE SWITCHING TO
LP GAS.
3. While the engine is operating, place the three posi-
tion LPG/Gasoline switch at the ground control sta-
tion to the center “off” position. Allow the engine to
operate without load, until the engine begins to
“stumble” from lack of gasoline.
4. As the engine begins to “stumble”, place the switch
to the LPG position, allowing the LP fuel to be sent
to the fuel regulator.
Changing from LP Gas to Gasoline
1. With engine operating on LP under a no load condi-
tion, throw the LPG/Gasoline switch at the ground
control station to the “Gasoline” position.
2. If engine “stumbles” because of lack of gasoline,
place the switch to the LPG position until engine
regains smoothness, then return the switch to the
Gasoline position. Repeat as necessary until engine
runs smoothly on gasoline.
3. Close the hand valve on the LP gas supply tank by
turning clockwise.
