235-27-2202 This is my first forklift, prior owner used it in this condition for a few years. It has a three stage mast. Issue is this: Tilt works properly, feels strong. Side shift has be disabled because of leaking/removed cylinder but I am not sure how. Aux valve and lever remain. Lift cylinder barely creeps up a few inches with lift lever only. If I hold side-shift lever either way, I can feel pressure build and then using mast lever, the mast lifts properly and has good "speed" and "hold", lowers smoothly. I can do the same using the tilt, get it to its stop, feel pressure build, hold it there, then mast works using mast lift lever. This has been the technique used for few years without further problems. Is there a specific hold or check valve I should be zeroing in on? Could it be related to the decommissioned side-shift? Thanks in advance.
