11 Check the nozzle size and check
that the nozzle cone is secure.
12 Remove the tractor from the gun cart and clear the area of operation.
13 Connect the feeder hose to the inlet on the traveller and lock it in place. Attach the other
end to the mainline or mainline valve.
14 If the hose is loose on the drum, use the hand crank to rotate the drum to tighten the hose.
Insure that the hose coils are stacked tightly together.
15 Adjust the brake handle to the full “ ON ” position after insuring that the hose is tight.
16 GRADUAL pressurization of the system may now begin. Keep the pressure low (under 50
PSI) until
ALL the air is purged from the system and a steady stream is flowing from the gun
nozzle. AFTER all the air is purged from the system, pressure may be slowly raised to a
maximum of 150 PSI at the inlet of the machine.
NOTE: Ideally, operating pressures at the inlet will be between 120 PSI and 150 PSI. This
will allow gun pressures ranging from approximately 50 PSI to 110 PSI (depending on
nozzle size, hose size and length). Assuming proper nozzle selection has been made
based on the pressure and flow volume available, proper droplet sizing and proper
gun action, an even and uniform watering pattern will result.
17 Check the mainline and inlet elbow connections.
START UP OF THE RETRIEVE CYCLE
1 Check the engine oil and fuel levels.
2 Open the fuel valve on the engine, move the
ON / OFF switch to the “ ON ” position and start
the engine.
NOTE: If after several attempts, the engine fails to start, check the shut off bar at the opposite end of the
machine to insure that BOTH shut off switches are depressed. The engine WILL NOT START if
either switch is released.
WARNING
Never leave the hand crank on the driveshaft. REMOVE IT IMMEDIATELY after use.
CAUTION
Operation of the machine with the inlet pressure below 110 PSI will allow the hose to flatten
slightly as it is rewound during the retrieve cycle. This flattening may cause the hose to lay im-
properly on the hose drum or make it impossible for all the hose to be rewound. In either case,
the hose must be pulled out to correct the problem. If you are unable to provide a minimum of
110 PSI to the inlet of the machine contact your dealer for help in improving your system design.
MODEL NOZZLE SIZE
2250 0.77”, 0.81” or 0.86”
2625 0.81”, 0.86”, 0.89” or 0.93”
3000S 1.18” or 1.26”
NOTE: Several nozzle sizes are supplied with the sprinkler gun. The “best” nozzle choice for
your application may take some experimentation to determine. Typically, two nozzle
sizes will perform well for each model. See the chart below for nozzles to try.
