INSTALLATION
RANGER 250 LPG

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
Ranger 250 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.
If growing bubbles appear, there is a leak. Re-tighten
connection or replace defective component. Retest to
make sure that there is no leak.
Leak test must be performed each time the fuel cylin-
der is replaced.
Always close the cylinder valve when the machine is
not being used.
