OPERATION
Trouble
Fault hours are added in the fault hour meter and can not be
deleted.
All fault messages are displayed on LED (A) as a collective
fault.
All fault messages can be acknowledged and deleted with but-
tons (B).
The display mode will start with one of two buttons (C).
When grease has leaked from pressurized safety valve (1),
consult your Komatsu distributor.
The pump has an automatic level control. If the grease level
falls below "min" mark, the lubrication process is stopped with
the fault message "FLL" shown on the display.
If fault message "FLL" is displayed, fill up with grease and reset
the fault with button (B).

HANDLE REAR VIEW MONITOR
• Never operate any of the switches while traveling. If you do so, there is a danger that you may make
an error in the machine travel operation, or neglect to watch the travel path ahead for safety, and as
a result cause a serious personal injury or death.
• The rearview monitor is an device for supporting a visual check if there is any obstacle in the rear
or the area around the machine. An image appearing on the monitor is limited.
When backing up the machine, be sure to make a visual check, not relying solely on the monitor.
Never rely solely on the monitor when backing up the machine.
• An image on the rear view monitor does not show an actual distance. Drive the machine slowly,
when backing it up.
• The distortion different from the actual state appears on an image on the rearview monitor.
So, look at the center of the screen as a guide.
