EXPLANATION OF MODES AND CONTROLS
Display panel B (1) has the function of displaying the following
four types of mode. (The diagram on the right shows the normal
screen before the mode display.)
Maintenance mode
This displays the time for replacing the filters or oil.
PM clinic auxiliary mode
This displays the engine speed and the oil pressure in the
hydraulic circuits.

There are variations (sub-items) in the four types of mode. For an explanation of the variations, see the following
items.
METHOD OF USING MAINTENANCE MODE (PAGE 3-28)
METHOD OF USING PM CLINIC AUXILIARY MODE (PAGE 3-30)
METHOD OF USING FAULT CODE DISPLAY MODE (PAGE 3-31)
METHOD OF USING USER ADJUST MODE (PAGE 3-32)
Each mode is operated by using information switch (2) and
buzzer cancel switch (3) on the dashboard in front of the
operator's seat.
After operating the switch, release the switch, and the switch will
return automatically to the center position as shown in the
diagram on the right.
The functions of each position of the switches are as follows.
<: Moves mode to left
>: Moves mode to right
: Selects mode
: Cancels mode
The four types of mode can be selected in a cycle by operating information switch (2) to > and < to give the
following sequence: Maintenance mode ←→ PM clinic auxiliary mode ←→ Fault code display mode ←→ Adju
stment mode ←→ Maintenance mode.
From the normal mode before giving the mode display, if buzzer cancel switch (3) is operated to  and held for
2.5 seconds, the maintenance mode is displayed. After that, if information switch (2) is operated to >, the mode
changes to the PM clinic auxiliary mode. If information switch (2) is operated to <, the mode changes to the user
adjust mode.
When any mode is being displayed, if the buzzer cancel switch is operated to , the screen returns the normal
screen shown before the mode display.
