Indicator Lamps
• Shutdown lamp
• Warning lamp
• Low oil pressure lamp
• Wait to start lamp (Glow plug warning lamp)
For information, refer to this manual, "Monitoring
System (Table for the Indicator Lamps)" for the
sequence of operation of the shutdown lamp and the
warning lamp.
The function of the wait to start lamp is automatically
controlled at engine start-up.
The function of the low oil pressure lamp is controlled
by the engine ECM. If low oil pressure is detected,
the lamp will be illuminated. The reason for the
illumination of the low-pressure lamp should be
investigated immediately.
The glow plug warning lamp will flash to show that
the engine speed is held at low RPM. This function
will be performed at engine starting and the duration
will depend on ambient temperature and engine
temperature.
The lamps will illuminate for 2 seconds to check that
the lamps are functioning when the keyswitch is
turned to the ON position. If any of the lamps stay
illuminated, or a lamp fails to be illuminated the
reason should be investigated immediately.

Engine Indicator Lamps
Note: When in operation the amber warning lamp
has three states, solid, flashing, and fast flashing.
The sequence is to give a visual indication of the
importance of the warning. Some application can
have an audible warning installed.
Ensure that the engine maintenance is carried out at
the correct intervals. A lack of maintenance can
result in illumination of the warning lamp. For the
correct intervals of maintenance, refer to the
Operation and Maintenance Manual, "Maintenance
Interval Schedule".
