Dual Fuel/LPG System
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.
Changing From Gasoline to LP Gas
NOTE:
Before climbing onto the platform, open hand valve
on LP gas supply tank by turning valve counterclock-
wise.
1. Start engine from platform control station.
2. With the engine under a no load condition, open the
hand valve on the LP gas supply tank by turning
counterclockwise.
3. While the engine is operating, place the two position
LPG/GAS SELECT switch at the platform control sta-
tion to LP gas.
Changing From LP Gas to Gasoline
1. With the engine operating on LP gas under a no load
condition, position the LPG/GAS SELECT switch at
the platform station to the GAS SELECT position.
2. If the engine ‘stumbles’ because of a lack of gasoline,
place the switch to the LPG position until the engine
regains smoothness, then return the switch to the
GAS SELECT position. Repeat as necessary until the
engine runs smoothly on gasoline.
3. Close the hand valve on the LP gas supply tank by
turning clockwise.
Using Liquid Petroleum (LP) Gas
CLOSE FUEL VALVE ON TANK WHEN PARKING SCISSOR LIFT MORE
THAN MOMENTARILY.
WHEN REFUELING LPG POWERED SCISSOR LIFTS, ALWAYS FOLLOW
MANUFACTURERS SPECIFICATIONS AND/OR APPLICABLE REGULA-
TIONS.
1. If machine is to be left overnight or longer, it must be
parked outside or the LPG tank removed and stored
outside.
2. LPG is extremely flammable. No smoking.
3. Only trained and authorized personnel are permitted
to operate filling equipment.
4. Fill LPG tanks outdoors. Stay at least 50 ft (15 m) from
buildings, motor vehicles, electrical equipment or
other ignition sources. Stay at least 15 ft (5 m) from
LPG storage tanks.
5. During transfer of LPG, metal components can
become very cold. Always wear gloves when refilling
or changing tanks to prevent “freeze burns” to skin.
6. Do not store LPG tanks near heat or open flame. For
complete instructions on the storage of LPG fuels,
refer to ANSI/NFPA 58 & 505 or applicable standards.
DO NOT USE AN LPG TANK THAT IS DAMAGED. A DAMAGED TANK MUST
BE REMOVED FROM SERVICE. FROST ON THE SURFACE OF A TANK,
VALVES, OR FITTINGS INDICATES LEAKAGE. A STRONG ODOR OF LPG
FUEL CAN INDICATE A LEAK.
Propane Fuel System Pressure Relief
THE PROPANE FUEL SYSTEM OPERATES AT PRESSURES UP TO 312 PSI
(21.5 BAR). TO MINIMIZE THE RISK OF FIRE AND PERSONAL INJURY,
RELIEVE THE PROPANE FUEL SYSTEM PRESSURE (WHERE APPLICA-
BLE) BEFORE SERVICING THE PROPANE FUEL SYSTEM COMPONENTS.
To relieve propane fuel system pressure:
1. Close the manual shut-off valve on the propane fuel
tank.
2. Start and run the vehicle until the engine stalls.
3. Turn the ignition switch OFF.
RESIDUAL VAPOR PRESSURE WILL BE PRESENT IN THE FUEL SYSTEM.
ENSURE THE WORK AREA IS WELL VENTILATED BEFORE DISCONNECT-
ING ANY FUEL LINE.
Propane Fuel System Leak Test
NEVER USE AN OPEN FLAME OF ANY TYPE TO CHECK FOR PROPANE
FUEL SYSTEM LEAKS.
Always inspect the propane fuel system for leaks after
performing service. Check for leaks at the fittings of
the serviced or replaced component. Use a commer-
cially available liquid leak detector or an electronic
leak detector. When using both methods, use the
electronic leak detector first to avoid contamination
by the liquid leak detector.
