(2) Button for boom priority mode
(3) Button for swing priority mode
(4) Button for fine control mode
(5) Button for user mode
(6) Travel alarm cancel switch
(7) Power mode switch
Start Service Mode and maintain power shift pressure at 2450 kPa (355 psi).
Depress the following three buttons on the operator monitor panel at the same time: button for fine control mode (4), button for user mode (5) and travel alarm cancel switch (6). Hold all three buttons down for at least three seconds.
The controller display (1) will be "00 00 00".
Input the service code "0E 32 3A". To increase the flashing character, push the button for boom priority mode (2). To decrease the flashing character, push the button for swing priority mode (3). To move the flashing character to the right, push the button for fine control mode (4). To move the flashing character to the left, push the button for user mode (5).

The controller display (1) will change to "10 -- 1". Note: If more than ten seconds pass between pushing the buttons, the controller display (1) will revert to the operation mode.
On the operator monitor panel, enter a fixed power shift pressure of 2450 kPa (355 psi) on the controller display (1). Adjust controller display (1) in order to attain a power shift pressure of 2450 kPa (355 psi) on the pressure gauge at pressure tap (1).
Move the flashing character to the far left. Increase the "1" to a "6".
Move the flashing character to the right and increase the "0" to a "6".
The last four characters on the controller display (1) will begin flashing. These characters represent the power shift pressure (kPa). Adjust the last four characters to "2450". To
