Hyster W45Z HD:
hydraulic issues

Hydraulics not holding when pallet jack goes up. I can hear the motor humming and all the hydraulic fluid retunes to hydraulic tank. Any ideas are greatly appreciated.

If what lumber jack told you after that it is possible the cylinder packing is bad and will not hold also if you have a hand set you could look at the switches and work them and look to make sure they work correctly.

It could be that you are lifting and lowering at the same time. Could be a stuck lowering switch. To diagnose disconnect the lowering solenoid and try to lift.
