EMERGENCY SHUTDOWN HEAD & LINKAGE - MAINTENANCE INSTRUCTIONS.

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 overspeeding 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.

When the handle is pulled sufficiently to stop the engine, a spring-loaded plunger prevents the

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.
