1. 1

   Inspect the electrical circuit: check the solenoid connector at External Valve 5, inspect the wiring harness for rub points, test the coil resistance on the solenoid, and verify ground integrity.

2. 2

   Check hydraulic fluid level and condition: look for dark fluid, burnt smells, or a milky appearance indicating water contamination and loss of viscosity.

3. 3

   Inspect for external hydraulic leaks at the valve fittings, quick couplers, or cylinders that could cause pressure drops.

4. 4

   Perform a pressure test with a hydraulic gauge to determine if the issue is isolated to the valve itself, the pump, or a restriction in the filter.

1. 1

   Remove lift cover cap

   Remove the two bolts securing the cap on the hydraulic lift cover.

2. 2

   Detach cap from standpipe

   Remove the cap and detach it from the standpipe. Caution: Ensure that the standpipe is not dislodged from its seat in the hydraulic pump.

3. 3

   Separate valve and base section

   Remove the three bolts securing the valve to the base plate of the control valve. Separate the valve and the base section.

4. 4

   Fit standpipe to new base plate

   Fit the standpipe into the inlet port of the new base plate.

5. 5

   Fit base plate to lift cover

   Fit the base plate to the lift cover, ensuring that the standpipe is correctly located into its seat on the hydraulic pump.

6. 6

   Secure base plate

   Secure the base plate to the lift cover.

7. 7

   Secure new control valve

   Secure the new control valve to the base plate using the three bolts removed earlier.

8. 8

   Replace filter and fluid

   Replace the hydraulic filter (mandatory every 300–500 hours) and top off with fresh UTTO hydraulic fluid.
