3-9.3. EMERGENCY SHUTDOWN HEAD & LINKAGE - MAINTENANCE INSTRUCTIONS .
a.
A manually operated emergency engine shutdown device enables the engine operator to stop
the engine in the event an abnormal condition should arise. If the engine continues to run after the engine
throttle is placed in the NO FUEL position, or if combustible liquids or gases are accidentally introduced into
the combustion chamber causing over spending of the engine, the shutdown device will prevent damage to the
engine by cutting off the air supply and thus stopping the engine. The shutdown device consists of a flap valve
mounted in the air inlet housing and a suitable operating mechanism.
b.
When the handle is pulled sufficiently to stop t e engine, a spring-loaded plunger prevents the
h
handle from being returned to the RUN position. It is necessary to pull the plunger manually before the
shutdown control can be returned to the RUN position.
NOTE
If a control cable is to be replaced, order by stock number and cable length.
