Oil Pressure Warning Light/Horn
The oil pressure warning light and horn signal indi
cate that engine oil pressure is below the safe oper
ating 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 o󰀨 after the en
gine 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 immediately and correct
the source of the problem before further engine op
eration.
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 Briggs &
Stratton 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.
Over Temperature Warning Light/Horn
The over temperature warning light and horn signal
indicate that the engine oil temperature is above the
safe operating limit (350° F or 177° 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 ns,
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.
