Hourmeter
The hourmeter, which is located on the instrument
panel, displays operating time accumulated while
the ignition switch is in the ON (RUN) position.
The hourmeter provides maintenance reminders af-
ter certain hours of operation. The hourmeter screen
will start ashing the reminder one hour prior to the
recommended interval and will continue until one
hour after the recommended interval (two hours).
The hourmeter does not have a manual reset
function.

* These intervals reect the actual time that the
reminder will ash (one hour prior to and one
hour after the recommended interval).
** This reminder is only used one time.
*** In normal operating conditions, oil changes in
100-hour intervals are acceptable. Walker and
the engine manufacturers recommend engine
oil changes every 50 hours in extremely dirty or
dusty conditions or for units with less than 100
hours annual use.
NOTE: The blinking hour glass on the display
means that the meter is operating properly.
Hourmeter
Voltmeter
The voltmeter displays battery and charging system
voltage. An indication of low or high voltage (the red
area) indicates an electrical system failure. The
cause of the failure should be determined and cor-
rected.
Oil Pressure Warning Light/Horn
The oil pressure warning light and horn indicate that
engine oil pressure is below the safe operating level
[below 3 to 5 PSI (21 to 34 kPa)]. This light (and
warning horn) will come on when the ignition is
turned ON, but should go off after the engine is start-
ed. If the light fails to come on when the ignition
switch is turned ON, it could indicate a burned out
bulb. If the light comes on during engine operation,
stop the engine immediately and correct the source
of the problem before further engine operation.
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).
Water Temperature Warning Light/Horn
The water temperature warning light and horn indi-
cate that engine coolant temperature is above the
safe operating limit and the engine is overheating.
If this light comes on, there may be a problem with:
● Radiator cooling air ow (material packed into
radiator cooling ns, clogged air intake screen)
● Cooling fan not operating
● Low coolant quantity in cooling system
Stop the engine and correct the source of the prob-
lem before further operation.
IMPORTANT: Continued operation of the engine
with an illuminated water temperature warning light
MAY result in severe engine damage.
