18. EXPLANATION OF COMPONENTS
CHARGE WARNING LAMP
Battery charging warning lamp indicates how the alternator is
generating power.
When functioning normally, this lamp lights up when the starting
switch is turned ON and goes off after engine startup.
Should the lamp light up during operation, check the electrical
system for any abnormality.
HOURMETER
Hourmeter begins to work when the engine starting switch key is
turned to the ON position, and indicates the cumulative value of
operating hours. While the hourmeter is in operation, the operation
indicator (hourglass) keeps flashing.
The last digit advances by 1 (meaning 0.1 hour) every 6 minutes
when the starting switch is at the ON or START position.
FAILURE INDICATOR LAMP
The Failure Indicator lamp begins to flash when some abnormality
has occurred in the control system.
If the lamp begins to flash, stop operations promptly and report the
trouble to the administrator, or call your Komatsu Forklift dealer for
technical assistance.
SEDIMENTER WARNING LAMP
(MODELS FD20/25/30)
Sediment warning lamp is used in combination with the
Maintenance lamp (see "MAINTENANCE LAMP (GASOLINE
ENGINE TRUCK)" above).
The Sediment warning lamp indicates that water has accumulated in
the fuel filter.
When functioning normally, this lamp lights up when the engine
starting switch key is turned to the ON position and goes off after
engine startup.
When the lamp lights up during operations, accumulation of drain water in the fuel filter is indicated. If water is left
inside the fuel filter, the fuel injection pump and injection nozzle function will likely be impaired.
See "(DIESEL ENGINE) DRAIN WATER FROM FUEL FILTER" on page 4-23 for details of the method of draining
the water.
