3.5 DUAL FUEL/LPG SYSTEM
IT IS POSSIBLE TO SWITCH FROM ONE FUEL SOURCE TO THE
OTHER WITHOUT ALLOWING THE ENGINE TO STOP. THE FOL-
LOWING 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 counter-
clockwise.
19. Start engine from platform control station.
20. 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 con-
trol 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 SIZZOR LIFTS, ALWAYS FOL-
LOW MANUFACTURERS 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
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 stan-
dards.
DO NOT USE AN LPG TANK THAT IS DAMAGED. A DAMAGED
TANK MUST BE REMOVED FROM SERVICE. FROST ON THE SUR-
FACE OF A TANK, VALVES, OR FITTINGS INDICATES LEAKAGE.
A STRONG ODOR OF LPG FUEL CAN INDICATE A LEAK.
