Open the software program for Cat ET.
Start the engine and warm up the hydraulics if necessary. The hydraulic oil temperature should be at least 50° C (122° F).
This pressure can be taken at high Idle or low idle, there should be no difference in pressure.

Actuate the quick coupler using the coupler switch (2) that is located to the right of the operator inside the cab. The quick coupler will then attempt to actuate for a few seconds. Do not actuate any other function at the time when checking the quick coupler. After the quick coupler has been actuated, check the quick coupler pressure.
The pressure should be 20000 700 kPa (2901 102 psi).
If the pressure is within specifications, shut off the machine. If adjustment is needed, refer the "Adjustment Procedure".Adjustment Procedure

Quick coupler valve is located underneath the cab on the left side of the machine
(4) Pressure reducing Valve
(5) Locknut
(6) Adjuster screw
Locate the quick coupler pressure reducing valve that is located underneath the cab on the left side of the machine as shown in Illustration 3.
Use a hex wrench to loosen the locknut (5) and an internal hex to adjust adjuster screw (6). Turn the adjuster screw clockwise in order to increase the pressure setting. Turn the adjuster screw counterclockwise in order to decrease the pressure setting.Note: The last movement should be clockwise before securing the locknut.
Tighten the locknut (5) to 17 3 N m (150 27 lb in).
Turn off the machine.
