Operating Instructions
31
Light Switch (For Optional Lights)
Operates headlights (when installed).
Hourmeter
The hourmeter displays operating time accumu-
lated while the ignition switch is in the ON position.
The hourmeter provides maintenance reminders
after certain hours of operation. The hourmeter
screen will start flashing 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 reflect the actual time that the
reminder will flash (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.

Circuit Breakers
Two manual reset circuit breakers are located on the
instrument panel. Each has a button that pops out if
the circuit breaker trips. The 10 amp circuit breaker
protects the circuits to the headlights, fuel valve so-
lenoid, safety switch relays and time delay module,
and GHS. The 7 amp circuit breaker protects the in-
strument panel circuits to the meters, warning lights,
and warning horn.
Warning Horn
The warning horn sounds to alert the operator that
an unsafe engine condition is being indicated -
when engine coolant temperature is too high or
engine oil pressure is too low. If the horn sounds,
check the indicator lights and water temperature
gauge and correct the problem before further
operation.
