Automatic Shutdown System
The engine is equipped with an automatic shutdown system to protect
it from damage should a low oil pressure or a high cylinder temperature
condition occur.
During a low-oil-pressure condition, the low-oil-pressure switch opens
cutting power to the throttle solenoid. During a high-cylinder-
temperature condition, the engine temperature switch shorts to
ground. This trips the circuit breaker and cuts power to the throttle
solenoid. Whenever power is cut to the throttle solenoid, it de-
energizes. When the throttle solenoid is de-energized, the engine
stops.
If the engine stops unexpectedly and the circuit breaker trips, it is a
sign of a problem with the fan belt. Check the fan belt and replace it if
necessary. Reset the circuit breaker before resuming use of the pump.
If the engine stops unexpectedly without the circuit breaker tripping,
check the amount of oil in the engine crankcase. Fill the engine
crankcase with oil as needed.

Important Operation Note
NOTICE
:
DO NOT run the pump in less than 1.2 m (4.0 ft.) of water!
At this level the water begins to form a funnel down to the bottom of the
suction line and strainer, allowing the pump to draw in air. The mixture
of air and water leads to a condition known as cavitation, which will
quickly destroy the impeller and the water chamber inside the pump
housing
