Operating Instructions
29
Hourmeter
The hourmeter displays operating time accumu-
lated while the ignition switch is in the ON position.
Voltmeter
The voltmeter displays battery and charging system
voltage. An indication of low or high voltage (below
11.5 volts or above 15.5 volts) indicates an electri-
cal system failure. The cause of the failure should
be determined and corrected.
Oil Pressure Warning Light
The oil pressure warning light indicates that engine
oil pressure is below the safe operating range [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 imme-
diately 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).
Over Temperature Warning Light
The over temperature warning light indicates that
engine oil temperature and/or cylinder head temper-
ature are above the safe operating limit and the en-
gine 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 prob-
lem 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 tem-
perature or head temperature condition exists).
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.
