Operation—Operating the Machine NOTE: DO NOT use manufacturer’s hose tags or markings on hose ends to identify hoses for this conversion procedure. The conversion must be done on the side of digging sensor manifold that is connected to the pilot control valves. 9. Install a -6 M 37 ° x -6 M 37 ° union to fabricated hose. Connect union to pilot line disconnected from the shockless valve 10. Route fabricated hose to digging sensor manifold. 11. Disconnect pilot line from port 6. Port numbers on digging sensor manifold are given from front to rear of machine and are not marked on manifold. 12. Connect fabricated hose to port 6. 6.
Switch pilot lines connected to port 2 and 5 at digging sensor manifold (9). 13. Route pilot line disconnected from port 6 to the shockless valve. Connect line to port B. 14. Install covers. 7. Disconnect pilot line from port B of the boom shockless valve (10). 8. Use the following table to fabricate the hydraulic hose needed.
