FUEL
A lift truck type coupler is provided on the supplied
fuel line for easy hand attachment to a lift truck type
LPG fuel cylinder. The fuel cylinder must meet D.O.T.
Specification 4E-240. The valve on the fuel cylinder
must be installed on the outlet marked “LIQUID”.
The engine will not develop full power if connected to
the vapor outlet.
Be certain that the cylinder valve is CLOSED before
attempting to attach the fuel supply hose coupler to the
cylinder. Connect the coupler to the fuel cylinder and
tighten by hand.
___________________________________________
After connecting the fuel supply to the supply cylinder,
open the valve on the fuel cylinder and leak test by
brushing a 50/50 soap and water solution on to the fol-
lowing connections:
• Both ends of the fuel hose where it enters the metal connector.
• The threaded fitting on the end of fuel hose attached to the GX
271 LPG fuel shut off solenoid.
• The fuel hose coupler and the connection to the cylinder valve.
• The stem of the cylinder valve and where the valve is attached
to the top of the cylinder.
• All other fittings on top of the fuel cylinder.
CAUTION
LPG fuel can cause fire or explosion.
-
• All leak testing must be done in a well
ventilated area free from all potential
ignition sources.
• Keep sparks and flame away from machine and
LPG supply cylinder.
• Do not expose the LPG supply cylinder to temper-
atures exceeding 120°F (49°C).
• Do not weld on or near the LPG supply cylinder.
• Do not smoke or allow any potential ignition sources
near the LPG supply cylinder.
• Always be certain that the LPG supply cylinder is NOT
in the welding circuit. Do not allow either welding
cable to come in contact with the supply cylinder.
