(1) Pressure tap (delivery pressure for drive pump)
(2) Pressure tap (delivery pressure for idler pump)
(3) Pressure tap (power shift pressure)
Connect a 60000 kPa (8700 psi) pressure gauge to pressure tap (1). Use this pressure gauge to monitor the crossover relief valve pressure setting of the right travel motor.
Connect a 60000 kPa (8700 psi) pressure gauge to pressure tap (2). Use this pressure gauge to monitor the crossover relief valve pressure setting of the left travel motor.
Connect a 6000 kPa (870 psi) pressure gauge to pressure tap (3).

After entering the last letter of the password, the monitor will continue with the "SERVICE" screen.
Repeatedly press down key (E) in order to highlight the "DEVICE TEST" line on the display.
After the "DEVICE TEST" line is highlighted, press OK key (I).
Once the "DEVICE TEST" screen is displayed, press down key (E) until "POWER SHIFT PRES" appears on the display.
When "POWER SHIFT PRES" is highlighted, press OK key (I).
Place the machine controls at the following settings: engine speed dial 5 and AEC switch OFF. Note: Press OK key (I) within 5 seconds after completion of Step 9.j.
The "POWER SHIFT PRES" will now be displayed. Line 4 of the display will now change to a numeric value. These characters represent the power shift pressure (kPa).
Press left key (D) or right key (F) in order to increase or decrease the numeric value that is displayed on line 4 of the display. Pressing left key (D) decreases the power shift pressure. Pressing right key (F) increases the power shift pressure. Note: The value for power shift pressure on the monitor may not always match the pressure reading on the pressure gauge. Adjust
