Attach a pressure gauge to the implement discharge gauge port (18) Testing Procedure - Implement Discharge Pressure
Start the engine and set to high idle.
With the engine in high idle, raise the linkage and allow the linkage to stall in the raise position. Refer to Table 1 for specifications.
If pressure is correct, lower linkage and stop engine. Properly purge the system and disconnect the gauge. If the pressure is not within specifications, refer to the "Adjustment Procedure - Implement Discharge Pressure" section. Adjustment Procedure - Implement Discharge Pressure

(H) Main implement valve
(J) Load sense relief valve
Locate the load sense relief valve (J) on the main implement valve (H). Best practice is to access the valve from the right side of the machine in the hitch.
Use a hex wrench to loosen the lock-nut and an internal hex to adjust the implement load sense pressure. Turn inwards to increase the pressure or outwards to decrease the pressure. Note: The final pressure adjustment must be inward to increase pressure. If the setting is too high, adjust the pressure down below the target pressure. Then, increase the pressure to reach the final
