3.14 DUAL FUEL/LPG SYSTEM
IT IS POSSIBLE TO SWITCH FROM ONE FUEL SOURCE TO THE OTHER WITHOUT
ALLOWING THE ENGINE TO STOP. 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 counterclockwise.
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 condition,
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 position.
3. Close hand valve on LP gas supply by turning clockwise.
Using Liquid Petroleum (LP) Gas
CLOSE FUEL VALVE ON TANK WHEN PARKING SIZZOR LIFT MORE THAN
MOMENTARILY.
WHEN REFUELING LPG POWERED SIZZOR LIFTS, ALWAYS FOLLOW MANUFAC-
TURERS SPECIFICATIONS AND/OR APPLICABLE REGULATIONS.
1. If machine is to be left overnight or longer, it must be
parked outside or the LPG tank removed and stored out-
side.
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 stor-
age 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.
