When the engine is switched off

Cause 1: The load-holding valve setting has been disturbed. Pollution in the valve may have caused the leakage.

  • Adjust the load holding valve, see chapter “7 Adjustment instructions” – Adjustment instructions for hydraulic valves. If this does not help, remove the valve and clean the details carefully. Mount and adjust according to the instructions. If this does not help, replace the load-holding valve with a new one.

Cause 2: The piston gasket in the lift cylinder is leaking.

  • Replace piston and piston rod gaskets in cylinder.
