The Electronic Monitor Panel will activate. Then, the monitor will display the output that is received from the controller. The Controller Service Program is divided into five functions. Each function is listed:
- Alerting the presence of abnormal engine operation
- Displaying the machine conditions (engine speed, hydraulic oil temperature, power shift pressure, etc)
- Displaying the existing electronic problems or the past electronic problems
- The electronic control components are adjusted and tested.
- Changes in various defaults in the controller
You should depress the switches on the monitor panel in order to start up the service program or the switches are depressed in order to change the functions. The corresponding switch and/or switches should be depressed until the required function is displayed on the character display.

Note: The engine can be running or the engine can be stopped, when the "Service Mode" is started. When the engine is stopped, the starter switch must be in the ON position. You should know the procedure to start up the "Service Mode" in advance.
- The following switches should be depressed and held for 2 seconds or more simultaneously: travel alarm cancel switch (22), fine control mode switch (25) and user mode switch (26) .
- The time display and the dial display on the character display (2) will change to a "0" and a "0". The left character position will flash.
- You need to enter the following security code: OE 32 3A.
Note: The security code must be entered within 10 seconds after the first procedure (1). Otherwise, the time display will return. You should learn the procedure of entering the security code in advance.
- The procedure to input information is listed:
- The figure that is blinking on the character display (2) can be changed. In order to change the figure, you should depress the boom priority mode switch (23) or the swing priority mode switch (24).
- The figure that is blinking increases (Boom priority mode switch (23) )
- The figure that is blinking decreases (Swing priority mode switch (24) )
The character position that is blinking can be shifted by depressing the fine control mode switch (25) or the user mode switch (26).
- The character position that is blinking shifts to the right (Fine control mode switch (25) ).
- The character position that is blinking shifts to the left (User mode switch (26) ).
- The figure that is blinking increases (Boom priority mode switch (23) )
- The figure that is blinking on the character display (2) can be changed. In order to change the figure, you should depress the boom priority mode switch (23) or the swing priority mode switch (24).
- After you enter the security code, the service mode is activated by depressing and holding the following switches for 2 seconds or greater: travel alarm cancel switch (22), fine control mode switch (25) and user mode switch (26). The service mode is automatically activated 10 seconds after the security code is entered.
- Now, the "Service Mode" is activated and the character display (2) will display "10" on the left two character positions and "1" on the right character position.
Note: Refer to the chart of Service Codes for selecting the functions for the "Service Mode".
Changing The Service Mode
- The boom priority mode switch (23) or the swing priority mode switch (24) is pressed in order to change the figures that are blinking on character display (2) .
- The figure that is blinking increases (Boom priority mode switch (23) )
- The figure that is blinking decreases (Swing priority mode switch (24) )
- The figure that is blinking increases (Boom priority mode switch (23) )
- The position that is blinking on the character display (2) can be shifted by depressing the fine control mode switch (25) and the user mode switch (26) .
- The position that is blinking shifts to the right (Fine control mode switch (25) )
- The position that is blinking shifts to the left (Swing priority mode switch (24) )
- The position that is blinking shifts to the right (Fine control mode switch (25) )
Note: Refer to the chart of Service Codes for selecting the functions for the "Service Mode".

Procedure To Stop The Service Mode
Note: One of the following two methods should be used.
- Turn the starter switch to the OFF position.
- The following switches should be depressed and held simultaneously for 2 second or more:
(22) Travel alarm cancel switch
(25) Fine control mode switch
(26) User mode switch
The service mode has been stopped, if the character display shows the position of the engine speed dial on the right two character positions and the time is shown on the left four character positions.
