Joystick (thumb slider)
For pressure on port "A", move the thumb slider on the left joystick to the left position. Then read the pressure on the pressure gauge that is connected to the load sensing cutoff pressure tap on the diverter valve. The diverter valve for port "A" is on the left side of the stick. Refer to Table 1 for the correct pressure.
For pressure on port "B", move the thumb slider on the left joystick to the right position. Then read the pressure on the pressure gauge that is connected to the load sensing cutoff pressure tap on the diverter valve. The diverter valve for port "B" is on the right side of the stick. Refer to Table 1 for the correct pressure.
If the load sensing cutoff pressure is not set to the proper specification, refer to the "Adjustment Procedure".Adjustment Procedure
If the load sensing cutoff pressure is too high or too low, perform the auto calibration procedure "Multi-Function-Auxiliary Calibration" in Cat® Electronic Technician (Cat ET) to adjust the load sense pressure.
Start Cat ET.
Select the "Service" on the tool bar and then clicking "Calibrations".
Select "Multi-Function-Auxiliary Calibration" under "Machine Control M300F".
Click on the "Start" button at the bottom of the screen.
After performing the calibration procedure, repeat the "Test Procedure"
If the load sensing cutoff pressure is
