Oil Pressure Warning Light
The oil pressure warning light indicates 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 ignition switch is
turned
ON,
it could indicate a burned out bulb. If the
light comes on during engine operation, stop the en-
gine immediately and correct the source of the prob-
lem 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).
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.
Over Temperature Warning Light
The over temperature warning light indicates that
the engine cylinder head temperature is above the
safe operating limit (450° F or 232° C) and the
en-
gine is overheating.
If this light comes on, there
may be a problem with the engine cooling 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 cylinder
head temperature condition exists.
