MACHINE OPERATIONS AND CONTROLS
7.
Turn fuel control dial to Low idle (MIN) position.
When the dial is in High idle (MAX) position, be sure to set
it to Low idle (MIN) position.

Even if the engine is started with the fuel control dial in a
position other than Low idle (MIN) position, the engine
speed is set to low idle speed.
You can change the engine speed by turning the fuel con-
trol dial to Low idle (MIN) position and then turning it to-
ward High idle (MAX) position.

cated on the machine monitor.

Contact your Komatsu distributor for details of the method

10. Perform the following inspection on the machine monitor.
1)
Check that the buzzer sounds for approximately 2
seconds and the camera image is displayed.
2)
Check that the following caution lamp and gauge
lights up for approximately 2 seconds.
