2000 Yale 4K capacity NR series reach truck, all functions work with proper vari speed...mast down, reach, side shift and traction work great. But mast "up" is either off or full speed only...no in between. Presume it is not the joystick pot as "reach" and sideshift use the same pot and they work fine. Is problem likely on control board, stuck proportional valve, or ?
Having said all that, I just bought this thing and never owned a reach truck before. Is it possible full speed "up" is just the way they were back in 2000 ? That would seem very odd but I have a Big Joe walkie type lift that is that way also, and it was that way brand new. But it's "up" is slower and more manageable...plus it's a relatively simplistic affair...I can't imagine Yale cheaping out in that regard on this one.
