MANIFOLD GP-EXHAUST 1654444 - Caterpillar

TYPE="LEVEL" DEPTH="1" @@@-->Engine Starting
For initial start-up of a new or rebuilt engine, make provisions to shutdown the engine should an overspeed occur. This may be accomplished by cutting off the air and/or fuel supply to the engine.
Air Starting - The air starting motors require a minimum of 689 kPa (100 psi) air pressure to operate properly. The maximum air pressure must not exceed 1723 kPa (250 psi).
Unaided starting can be accomplished down to a temperature of 0°C (32°F). If a potential for lower starting temperature exists, consult your Caterpillar dealer.
1. Open and close the drain valve on the bottom of the air tank to drain condensation and oil carry-over.2. Check the air supply pressure. The air starting system must have 689 kPa (100 psi) minimum to 1723 kPa (250 psi) maximum to operate properly.3. Check the oil level in the air starting motor lubricator. Keep the lubricator bowl at least half full. Add oil if necessary.4. Turn the handle on the fuel priming pump in a clockwise (CW) direction to prime the system. Turn the handle until resistance to fuel flow is felt.5. Turn the Engine Control Switch (ECS) to the MANUAL START position. If the engine is not prelubed, the prelube system will operate before the engine starts.6. If the oil pressure does not raise within 15 seconds, shut down the engine.7. When the ECS is in the AUTO position, the engine may be started automatically via remote contacts.Engine Stopping
Stopping the engine immediately after it has been operating under load can result in over heating and accelerated wear of the engine components. Follow the stopping procedure outlined below to allow the engine to cool. Excessive temperatures in the turbocharger centerhousing may cause oil coking problems.
1. Remove the load from the engine.2. Operate the engine at RATED speed without a load until:* The jacket water outlet temperature for diesel engines reads 85°C (185°F). There must be NO water temperature rise across the engine.* The exhaust port temperature is reduced to at least 204°C (400°F). This may take as long as ten minutes.3. Reduce the engine speed to low idle and continue to operate the engine without load for at least five minutes to further cool the engine. 4. Check the crankcase oil level while the engine is idling. Maintain the oil level between the ADD and FULL marks on the "Engine at Low Idle with Warm Oil" side of the dipstick. 5. The engine may be stopped by turning the Engine Control Switch (ECS) to the STOP position (1).6. Engines that are started with the ECS in the AUTO position (2) will stop after the remote contacts are opened and the cool-down cycle times out. The length of the cool-down cycle is controlled by an adjustable resistor on the cool-down module inside the control panel.Emergency Stop Procedure
If the need for emergency engine shutdown occurs, use the following procedure to stop the engine.
Do not restart the engine until the problem necessitating the emergency stop has been located and corrected.
