The pressure tap is located behind the left rear access door. (1) Load sensing signal pressure
Connect a 60000 kPa (8700 psi) pressure gauge to pressure tap (1) .
Start the engine.
Place the engine speed at the HIGH IDLE position.Test
Place the power mode switch in the MODE P position.
Lower the left console.
Slowly move the bucket control lever to the full BUCKET CLOSE position. Check the load sensing signal pressure at pressure tap (2). Refer to Testing and Adjusting, "Specifications" in this manual for the correct load sensing signal pressure.Adjust

Main control valve (2) Adjustment screw (Load sensing signal limiter valve)
To adjust the load sensing signal pressure, slowly move the bucket control lever to the full BUCKET CLOSE position.
Loosen the locknut on adjustment screw (2) .
Turn the adjustment screw for signal limiter relief valve (2) clockwise in order to increase the load sensing signal pressure. Turn adjustment screw counterclockwise in order to decrease the load sensing signal pressure.Note: A quarter turn of adjustment screw changes the pressure by approximately 4500 kPa (650 psi).Note: Always make the final pressure adjustments on the pressure rise.
Tighten the locknut.
