What to do if the motor starts but my Nussbaum Lifting Systems does not lift?

  Antonio MorrisonAug 5, 2025
  If the motor of your Nussbaum Lifting Systems starts but the lift isn't lifting, several issues could be the cause. First, the vehicle might be too heavy; try unloading it. Second, the oil level could be too low; refill it with the lift in the lowest position. Other potential causes include a defective pressure relief valve, leakage in the hydraulic system, a defective coupling between the motor and pump, or a defective gear pump. For the last four issues, it's best to call your service partner.

What to do if my Nussbaum Lifting Systems lift does not lower?
- K
  Kelly OwenAug 12, 2025
  If your Nussbaum Lifting Systems does not lower, it might be due to a few reasons. The lift could be standing on an obstacle. Alternatively, the lift might be locked in the ratchet. Also, the seat valve could be defective; examine the electrical power supply to the valves. Finally, the photo electric might be interrupted, or the reflector could be dirty; check the photo electric/reflector.

How to troubleshoot a Nussbaum Lifting Systems when the motor does not start?

  kathleenmuellerAug 20, 2025
  If the motor of your Nussbaum Lifting Systems won't start, begin by examining the power supply, main switch, main fuse, and the fuse in the operating unit. Also, check if the fee line is cut and repair it if necessary. If the thermal switch in the motor is active, allow it to cool down. The top limit switch might also be active or defective, so examine it. Lastly, check the lifting button for defects. If these steps don't resolve the issue and the motor is defective, call your service partner.

Why is there no automatically leveling of the platforms on my Nussbaum Lifting Systems?
- D
  Douglas AguilarAug 27, 2025
  If the platforms of your Nussbaum Lifting Systems are not automatically leveling, it could be due to a defective pneumatic valve (valve for the equalization ball valve). In this case, exchange the valve. Another possible cause is a defective seat-valve at the cylinders, which requires an emergency lowering.
