Hi folks,We have a recently bought Terex SS1048 lift that we are having problems with the hydraulic oil overheating.At cold start-up after letting machine idle for 30-40 minutes the oil is right next to cooking in the reservoir.When i push in the hydraulic pump cutout button the engine will free up like the pump is at full stroke with no functions activated.Does anyone by chance have a hydraulic schematic or a service manual to further troubleshoot this machine? it seems the service manual is hard to come by. Thanks
