  If the Werner Weitner Water Pump cylinder does not advance, advances slowly, or advances in spurts, several factors could be at play. Here's what to check: * **Oil Level:** Ensure the oil level in the pump reservoir is adequate. Refill according to the maintenance instructions. * **Drain Valve:** Verify the drain valve is closed. * **Hydraulic Couplers:** Confirm that all couplers are fully tightened. * **Load Weight:** Ensure you are not attempting to lift more than the rated tonnage. * **Air in System:** If air is trapped in the system, remove it following the provided instructions. * **Cylinder Damage:** Inspect the cylinder for any damage. If damaged, have it serviced by an authorized dealer or Weitner themselves.
