I’ve got a hi ranger lineman 2 lift. When you press the trigger in the handle in the boom and twist it to swing to your right there seems to be either a dead spot or sweet spot. Two far you get nothing, not enough twist you get nothing but a small bounce. Possibly air in the lines? Also the bucket has a rotate function, it won’t rotate left or right but when you twist the valve for that function you can tell it gets pressure. Any help is greatly appreciated.
