Operating Instructions
35
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.
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
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).
Over Temperature Warning Light/Horn
The over temperature warning light and horn indi-
cate that the engine cylinder head temperature is
above the safe operating limit (450° F or 232° C)
and the
engine is overheating.
If this light comes
on, there may be a problem with the engine cool-
ing system (material packed into cylinder head
cooling fins, clogged air intake screen, etc.). Stop
the engine and correct the source of the problem
before further operation.
IMPORTANT:
Continued operation of the engine
with an illuminated over temperature warning light
MAY
cause severe engine damage if a high cylin-
der head temperature condition exists.
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 illumi-
nates during operation, 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.
