Pulling the 3" Certa-Set lateral lines into an adjacent field

1. Survey field conditions and decide on retrieval direction. Considerations should be taken for pipeline length, spline direction and

work area limitations (roads, headland sizes, ditches).

2. Disconnect pipe from the main line connection. Remove swing joints (19 foot 3" Certa-Set lateral pipe) and transition fittings.

3. Disconnect 3" Certa-Set end plugs and drain line completely.

Failure to drain lines will result in damage to the pipe

and will void the warranty

4. Connect the pipeline to the tractor using a pulling connection.

5. Slowly pull the pipeline, ensuring that it is not binding up on any obstruction.
6. Tow pipe into place in next field and reconnect as necessary.

Swing joints are on both

sides of the Nelson valve
