Does anyone know about electric forklifts? I have a clark 3 wheel 4400 lb. It wont lower the mast all of a sudden. Nothings tight it doesnt seem to release the mast pressure. Valve makes no sound now when you pull on it. Thinking solenoid or relay. Just wondering if anyone knew?

It's a Clark tm 25. The mast will settle but really really slowly. It happened all of a sudden. Was working fine. I can't see anything tight on the mast.

Up tilt and side shift work fine.
