Water Temperature Warning Light (Model MTL)
The water temperature warning light indicates that
engine coolant temperature is above the safe oper-
ating limit and the engine is overheating. If this
light comes on, there may be a problem with:
•
Radiator cooling air flow (material packed into
radiator cooling fins, clogged air intake screen)
•
Cooling fan not operating
•
Low coolant quantity in cooling system
Water Temperature Gauge (Model MTL)
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.
Engine Service Light (Model MTEFI)
The engine service light indicates the Engine Con-
trol Unit (ECU) has detected a fault in the engine
performance. When this light illuminates during op-
eration, contact an authorized Kohler Service 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, RUN is the position the key returns to after
starting, and “S” is the START position. When start-
ing the engine, turn the key clockwise to the “S” po-
sition. Do not hold the key in the “S” position longer
than 10 seconds. If the engine does not start, return
the key to the “O” position for at least 60 seconds be-
fore making a restart attempt. Prolonged cranking
can damage the starter motor and shorten battery
life. Release the key when the engine starts, and it
will return to the “RUN” position. To stop the engine,
rotate the key counterclockwise to the “O” position.
Ignition Switch
Light Switch (For Optional Lights)
Operates headlights (when installed).
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.
WARNING
If engine cooling system overheating is
indicated, continued operation of the en-
gine, even for a short time, COULD result
in fire, risk of personal injury, and severe
damage to equipment.
