CHECK MONITOR GROUP
NOTICE
When performing the check before starting, do not rely only on these monitors. Always refer to "OPERATION (PAGE 3-76)" to
perform these checks.
Park the machine on level ground and then check the monitor lamps.
Confirm that monitor lamps light up about 2 seconds after the starting switch is turned to the ON position. If any monitor lamp
does not light, contact your Komatsu distributor to inspect and repair.
REMARK
When the starting switch is turned to the ON position, before starting the engine, the caution lamps flash for 2
seconds, the warning lamps light up for 2 seconds, and the alarm buzzer sounds for 2 seconds.
The caution lamps cannot be checked for any malfunction until at least 5 seconds after the engine has been
stopped.
This displays the basic items among the check before starting items that must be checked before starting the
engine. If there is any abnormality, the caution lamp for that location will flash.
