STARTING MOTOR GP-ELECTRIC 2071511 - Caterpillar

Emergency shutoff controls are for EMERGENCY use ONLY. DO NOT use emergency shutoff devices or controls for normal stopping procedure.
Ensure that any components for the external system that support the engine operation are secure after the engine is stopped.Emergency Stop Button
Illustration 1 g00104303
Typical Emergency Stop Button
The emergency stop button on a (S/N: 7BL) stays in the OUT position for normal engine operation. Push in the emergency stop button. The button locks into position until the button is reset. The engine will not start when the button is locked. Turn the emergency stop button clockwise in order to reset.
Stopping the engine immediately after it has been working under load can result in overheating and accelerated wear of the engine components.If the engine has been operating at high rpm and/or high loads, run at low idle for at least three minutes to reduce and stabilize internal engine temperature before stopping the engine.Avoiding hot engine shutdowns will maximize turbocharger shaft and bearing life.

A Typical Emergency Stop Button for the (S/N: 3JK) and the (S/N: 8RG)
For the (S/N: 3JK) and the (S/N: 8RG), the emergency stop button sends a signal to the ECM. This button does NOT need to be reset.The air inlet shutoff lever stops the engine, if equipped. You can also use the manual shutoff to stop the engine. A linkage to these devices is installed by either the customer or the vessel's OEM.Air Inlet Shutoff Lever
Air inlet shutoff lever (1) rotates a shaft. This shaft contains plates that restrict the air flow to the combustion chamber. This starves the engine of air.

Manual Shutoff Shaft
Manual shutoff shaft (2) overrides the governor. This mechanism moves the fuel control linkage to the FUEL-OFF position.Stopped Engines
Stopping the engine immediately after it has been working under load can result in overheating and accelerated wear of engine components.Excessive temperatures in the turbocharger centerhousing will cause oil coking problems.Allow the engine to gradually cool before stopping the engine
After the engine has stopped, follow these procedures:
Check the crankcase oil level. Maintain the oil level between the "ADD" and "FULL" marks on the "ENGINE STOPPED" side of the dipstick.
Repair any leaks, and perform minor adjustments. Take care to tighten loose bolts, etc.
Note the service hour meter reading. Perform the periodic maintenance that is described in this Operation and Maintenance Manual, "Maintenance Interval Schedule" (Maintenance Section).
Fill the fuel tank. This helps to prevent the accumulation of moisture in the fuel. Do not overfill the fuel tank.
Allow the engine to cool. Check the coolant level. Maintain the coolant level to the following amount:
13 mm (1/2 inch) from the bottom of the fuel tank filler neckNote: If freezing temperatures are expected, check the coolant for proper antifreeze protection. The cooling system must be protected against freezing. Take extra care to use an antifreeze that is capable of working at the lowest predicted temperature. Add the proper mixture of coolant and of water, as needed.
