C. Engine Stop Switch
Some engines are equipped with an optional Stop Switch.
This rocker switch is used to shut off the ignition that
supplies the spark plug with power. Pressing the "OFF"
position will turn the engine off when it is running. This
switch must be in the “ON” position or the engine will not
start. See Figure 10.
D. Low Oil Shutdown Switch
Some engines are equipped with an optional Low Oil
Shutdown Switch. This is a lighted rocker switch that is
connected to a float switch in the engine crankcase. When
oil level drops below a predetermined level, the float switch
cuts off current to the spark plug and the engine stops
running. Oil must be added to the engine to bring the oil to
the proper level before the engine will start. If an attempt is
made to start the engine before oil is added, the switch will
flash as the engine rotates, and the engine will not start.
See Figure 11.
Pressing the “OFF” position of the Shutdown Switch while
the engine is running, will turn the engine off. The engine
will not start with the switch in the “OFF” position.
E. Low Oil Shutdown Light
Some engines are equipped with an optional Low Oil
Shutdown System that includes a light but does not include
a rocker switch. The float switch in this system will shut the
engine off while it is running if the oil level in the crankcase
falls below a predetermined level. Oil must be added to the
engine to bring the oil to the proper level before the engine
will start. If an attempt is made to start the engine before oil
is added, the light will flash as the engine rotates, and the
engine will not start. See Figure 11.
F. Low Oil Shutdown System
Some engines are equipped with an optional Low Oil
Shutdown System that does not have a rocker switch or a
light. The float switch in this system will shut the engine off
while it is running if the oil level in the crankcase falls below
a predetermined level. Oil must be added to the engine to
bring the oil to the proper level before the engine will start.
