2-9.5 Emergency Engine Shutdown. The emergency engine shutdown control, when pulled, will trip the air

shut-down valve located between the air inlet housing and the blower to shut off the air supply to the engine.

Lack of air will prevent further combustion of the fuel and stop the engine. The emergency engine shutdown

control must be pushed back-in after the engine stops so the air shutdown valve can be opened for restarting

after the malfunction has been corrected. Use the procedure below to shut down the engines in an emergency.

CAUTION

Using an emergency engine air shutdown control to stop an

engine may cause damage to engine oil seals. The emergency

engine shutdown control should be used in engine room fire or

runaway engine emergencies only.

Pull the applicable emergency engine shutdown control (19) (T-handle) on the control console, port

side, and hold it there until engine stops.

Push in the emergency engine shutdown control after engine stops.

2-9.6 Inoperable Rudders. If the rudders become fouled or unusable, the LCM-8 can be steered by varying

engine speed as follows.

2-9.6.1 Steering By Engine Speed.

To turn the LCM-8 to port while underway, decrease the port engine speed while maintaining the

starboard engine speed. The turning rate to port is predicated on the difference in speeds of the port

and starboard engines. Set the port engine throttle to the appropriate engine speed for the desired

turning rate When the turn is completed, increase the port engine speed to that of the starboard

engine.
