Dual Fuel/LPG System
IT IS POSSIBLE TO SWITCH FROM ONE FUEL SOURCE TO THE OTHER
WITHOUT ALLOWING THE ENGINE TO STOP. THE FOLLOWING INSTRUC-
TIONS 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. While engine is operating, place the dual fuel switch
at platform control station to the LPG position. Allow
engine to operate, without load, until engine begins
to “stumble” from lack of gasoline. At this time the
machine is 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 LPG/GASOLINE switch at platform control
station to GASOLINE position.
2. If engine “stumbles” because of lack of gasoline,
place switch to LPG position until engine regains
smoothness, then return switch to GASOLINE posi-
tion.
3. Close hand valve on LP gas supply by turning clock-
wise.
Using Liquid Petroleum (LP) Gas
CLOSE FUEL VALVE ON TANK WHEN PARKING SIZZOR 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.
3.15 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.
3.16 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.
