Operating Instructions<br />
Hourmeter<br />
The hourmeter displays operating time accumulated<br />
while the ignition switch is in the ON position.<br />
Voltmeter<br />
The voltmeter displays battery and charging system<br />
voltage. An indication of low or high voltage (below<br />
11.5 volts or above 15.5 volts) indicates an electrical<br />
system failure. The cause of the failure should<br />
be determined and corrected.<br />
Oil Pressure Warning Light<br />
The oil pressure warning light indicates that engine<br />
oil pressure is below the safe operating range [below<br />
3 to 5 PSI (21 to 34 kPa)]. This light (and warning<br />
horn) will come on when the ignition is turned ON, but<br />
should go off after the engine is started. If the light<br />
fails to come on when the ignition switch is turned ON,<br />
it could indicate a burned out bulb. If the light comes<br />
on during engine operation, stop the engine immediately<br />
and correct the source of the problem before<br />
further engine operation.<br />
IMPORTANT: Continued operation of the engine<br />
with an illuminated oil pressure warning light MAY<br />
cause severe engine damage (if a low oil pressure<br />
condition exists).<br />
Ignition Switch<br />
The ignition switch is used to start and stop the engine.<br />
The switch has three positions: “O” is the OFF<br />
position, RUN is the position the key returns to after<br />
starting, and “S” is the START position. When starting<br />
the engine, turn the key clockwise to the “S” position.<br />
Do not hold the key in the “S” position longer<br />
than 10 seconds. If the engine does not start, return<br />
the key to the “O” position for at least 60 seconds before<br />
making a restart attempt. Prolonged cranking<br />
can damage the starter motor and shorten battery<br />
life. Release the key when the engine starts, and it<br />
will return to the “RUN” position. To stop the engine,<br />
rotate the key counterclockwise to the “O” position.<br />

START<br />
Over Temperature Warning Light<br />
The over temperature warning light indicates that<br />
engine oil temperature and/or cylinder head temperature<br />
are above the safe operating limit and the engine<br />
is overheating [above 305° F (152° C) oil or<br />
450° F (232° C) cylinder head]. If this light comes<br />
on, there may be a problem with:<br />
• Engine cooling system (material packed into cylinder<br />
head cooling fins, clogged air intake screen)<br />
• Low oil level in crankcase<br />
Stop the engine and correct the source of the problem<br />
before further operation.<br />
Ignition Switch<br />
Light Switch (For Optional Lights)<br />
Operates headlights (when installed).<br />
Warning Horn<br />
The warning horn sounds to alert the operator that<br />
an unsafe engine condition is being indicated -<br />
when engine temperature is too high or engine oil<br />
pressure is too low. If the horn sounds, check the<br />
indicator lights and correct the problem before further<br />
operation.<br />
IMPORTANT: Continued operation of the engine<br />
with an illuminated over temperature warning light<br />
MAY cause severe engine damage (if a high oil temperature<br />
or head temperature condition exists).<br />
