Hourmeter
The hourmeter, which is located on the instrument
panel, displays operating time accumulated while
the ignition switch is in the ON (RUN) position.
Some tractors are equipped with hourmeters that
provide maintenance reminders after certain hours
of operation. The hourmeter screen will start flash-
ing the reminder one hour prior to the recommend-
ed interval and will continue until one hour after the
recommended interval (two hours).
●
4-6 hours: Oil Change (Break-In)
●
24-26 hours: Lube
●
49-51 hours: Oil Change
The hourmeter reminders are set for the most
frequent service intervals. Follow the intervals
outlined in the Maintenance Schedule Chart on
page 58 for this tractor.
The hourmeter does not have a manual reset
function.
NOTE: The blinking hour glass on the display
means that the meter is operating properly.
Hourmeter
Voltmeter
The voltmeter displays battery and charging sys-
tem voltage. An indication of low or high voltage
(the red area) indicates an electrical system
failure. The cause of the failure should be deter-
mined and corrected.
Water Temperature Gauge
The water temperature gauge monitors engine
cooling system temperature. If engine coolant
temperature exceeds 230° F (110° C), an overheat
condition exists; the water temperature light will
come on and the warning horn will sound.
WARNING
If engine cooling system overheating is in-
dicated, continued operation of the engine,
even for a short time, COULD result in fire,
risk of personal injury, and severe damage
to equipment.
Oil Pressure Warning Light/Horn
The oil pressure warning light and horn indicate
that engine oil pressure is below the safe operating
level [below 7 PSI (48 kPa)]. This light (and
warning horn) will come on when the ignition is
turned ON, but should go off after the engine is
started. If the light fails to come on when the igni-
tion switch is turned ON, it could indicate a burned
out bulb. If the light comes on during engine oper-
ation, stop the engine immediately and correct the
source of the problem before further engine opera-
tion.
IMPORTANT: Continued operation of the engine
with an illuminated oil pressure warning light MAY
cause severe engine damage (if a low oil pressure
condition exists).
