Operating Instructions
27
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 engine immedi-
ately and correct the source of the problem 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 (Model MBS26 Only)
The engine service light indicates the Engine Control
Unit (ECU) has detected a fault in the engine perfor-
mance. When this light illuminates during operation,
contact an authorized Kohler Service dealer to diag-
nose the fault.
IMPORTANT:
Continued operation of the engine with
an illuminated engine service light will result in sub-
standard performance and
MAY
cause engine dam-
age if not corrected as soon as possible.
Over Temperature Warning Light
The over temperature warning light indicates that en-
gine oil temperature and/or cylinder head tempera-
ture are above the safe operating limit and the
engine
is overheating
[above 305° F (152° C) oil or 450° F
(232° C) cylinder head]. If this light comes on, there
may be a problem with:
•
Engine cooling system (material packed into cyl-
inder head cooling fins, clogged air intake screen)
•
Low oil level in crankcase
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 oil temperature
or head temperature condition exists).
