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.
Engine Service Light
The engine service light indicates that the engine
Electronic Control Unit (ECU) has detected a fault in
the engine performance. When this light illuminates
during operation, contact an authorized Kohler Ser-
vice dealer to diagnose the fault.
IMPORTANT:
Continued operation of the engine
with an illuminated engine service light will result in
sub-standard performance and
MAY
cause engine
damage if not corrected as soon as possible.
Ignition Switch
The ignition switch is used to start and stop the en-
gine. The switch has three positions: “O” is the
OFF
position, “I” is the
ON (RUN)
position that the key
returns to after starting, and is the
START
posi-
tion. When starting the engine, turn the key clock-
wise to the
START
position. Do not hold the key in
the
START
position longer than 10 seconds. If the
engine does not start, return the key to the “O” posi-
tion for at least 60 seconds before making a restart
attempt. Prolonged cranking can damage the start-
er motor and shorten battery life. Release the key
when the engine starts, and it will return to the
ON
(RUN)
position. To stop the engine, rotate the key
counterclockwise to the “O” position.

Light Switch (For Optional Lights)

Warning Horn
The warning horn sounds to alert the operator that
an
unsafe engine condition
is being indicated -
when engine temperature is too high or engine oil
pressure is too low. If the horn sounds, check the
indicator lights and correct the problem before fur-
ther operation.
Circuit Breakers
Two manual circuit breakers are located on the in-
strument panel. Each has a button that pops out if
the circuit breaker trips. The 10 amp circuit breaker
is used for the optional headlights circuit. The 7 amp
circuit breaker protects the instrument panel circuits
to the meters, warning lights, and warning horn plus
the safety switch circuits and the GHS. In addition,
an auto reset 30 amp master circuit breaker is lo-
cated near the battery and an auto reset 40 amp
circuit breaker protects the radiator cooling fan cir-
cuit. Finally, there is a 10 amp fuse protecting the
ECU.
