  If the John Bean Jacks lift doesn't hold pressure and slowly descends, it could be due to a fluid leak at the pump, hose, or cylinder, requiring you to repair the leak and refill the reservoir. Alternatively, the lowering valve might be damaged, necessitating replacement of the damaged or missing parts. A pump malfunction can also cause this issue, in which case you should contact customer service to have the pump serviced.

  If the pump on your John Bean Jacks runs but the lift doesn't rise to its full height, it might be low on fluid. Lower the Jack Beam, check the fluid level, and replenish if needed. Also, the pump vent might be closed; try loosening the metal vent knob on the pump body.

  If the John Bean Jacks pump runs but the lift won't rise after contacting the load, ensure you're not exceeding the lift's capacity as listed on the tag. Also, check for fluid leaks at the pump, hose, or cylinder; repair any leaks and refill the reservoir if needed. For pump malfunction, contact customer service to have the pump serviced. Ensure that the pump is not low on fluid, lower the Jack Beam and check the fluid level, and replenish if required.

  If the John Bean Jacks pump won't start when the “UP” button is pressed, check the air supply at the pump, it requires 90 – 120 psi of shop air. Also, inspect the air supply line for leaks and correct them if found. Look for any restrictions in the air line, such as kinks, and correct them. If the air motor is malfunctioning, contact customer service to have the pump serviced.
