A visual inspection of the system is the first step of troubleshooting a problem. In order to perform the inspection, turn off the engine and lower the implements to the ground.

1. Check the level of the oil in the hydraulic tank.

2. Inspect all lines and connections for damage or leaks.

3. Remove all of the elements in the high pressure screens and check the elements for material that would indicate damage to a component.

4. Inspect the control linkage from the hydraulic activation control selector valve for bent components, broken components or damaged components.
