Additional Information: Bleeding Air from Hydraulic System

The manual includes specific instructions for bleeding air from the hydraulic system when the hydraulic oil has been drained or components such as the suction filter or motor parts have been replaced:

1. Remove the air bleed plug on top of each pump and fill with hydraulic oil.
2. Tighten the air bleed plug temporarily, start the engine at a slow idle, then loosen the plug to allow air to escape until oil appears.
3. Tighten the plug securely using a wrench at 95 Nm force.
4. Repeat for other pumps as necessary.

Important: Operating the engine with insufficient hydraulic oil can damage the pump. Ensure air is completely bled before running the engine.
