LS (Load Sensing) Differential: 1.5 - 2.0 MPa

Unloading Pressure: 3.0 - 4.5 MPa

6. INSTALLATION & COMMISSIONING PROTOCOL

Case Priming: MANDATORY. Fill the pump housing with 1.5 liters of clean hydraulic oil before starting the engine.

System Flushing: If the previous pump failed, the oil cooler and all hydraulic lines must be professionally flushed to remove metal debris.

Filtration: Replace the main return filter and the pilot line filter. Clean the magnetic suction strainer in the tank.

Air Bleeding: Run the engine at low idle for 10 minutes and cycle all cylinders to full stroke several times to purge air.
