Good morning! I am new here and had an issue yesterday when operating my National 1400 Boom truck. I was setting trusses and when winching down, I would slow down to set them down gently. When I did that, it stopped winching down. I would start moving the lever and it would not move until I was almost full stroke and then it would shoot down. It was almost like the cable was "stuck" and then finally broke free, but it was not actually stuck on anything. I am going to look at it today but I figured I would ask first to get some ideas. Also, when I was doing multiple things like swinging and winching (up or down) or booming up/down and winching and I stopped the other movement while still winching, it would make the winching act funny for a split second. Almost like it had a surge of pressure to the winch controls for a split second and it would make the cable slap on the top of the boom. Normally if I was giving it a ton of throttle and stopped one motion, yes the engine would Rev up more because it was under less of a load and it would start to move faster, but it would never do this. Hoping that the issues are connected. Any ideas?
