PISTON & ROD GP 6I1212 - Caterpillar

Starting The Engine
1. Perform all before-starting inspections. Refer to "Before Starting" in the Engine Operation And Maintenance Guide. 2. Turn Engine Control Switch (ECS) (1) to the Manual Start position. The engine will start and run as long as the ECS (1) is in this position.3. When the engine starts, the engine fault circuits are now functional (armed). Should a fault occur, the engine will be automatically shut down. To restart the engine after being shutdown by a fault, first correct the fault condition, then turn ECS (1) to the Off-Reset position. Next start the engine as per step 2.4. After the engine starts and its systems have stabilized, apply the load.5. Regulate the frequency of the generator with the optional Governor Switch (GS) or the optional Speed Potentiometer (SP) (2) or the Manual Governor Control Lever on the engine.6. Regulate the voltage level of the generator with the voltage adjust rheostat (VAR) (3).Stopping The Engine
1. Remove the load from the engine.2. Turn the Engine Control Switch (ECS) to the Stop position. This will allow the engine to run for the preset, or programmed cool down time before shutdown. If high idle cool down at no load is not desired proceed to Step 3.3. Reduce engine speed to Low idle (approximately 2/3 the full load speed of 60 Hz units or 4/5 full load speed of 50 Hz units). Push down on the Governor Switch (GS) until low idle is achieved (for governors with electric motors), or turn down the Speed Potentiometer (SP) (for electronic governors). For manual governors move the Governor Control lever to the low idle position.4. While the engine is at low idle, measure the engine oil level. Oil level must be maintained between the Add and Full marks on the Engine Running side of the dipstick. For 3200 Series engines, the oil level cannot be measured with the engine running.5. Allow the engine to cool down while running at low idle (approximately five minutes). After the engine cools, turn the Engine Control Switch to the Off-Reset position.Emergency Stopping
The Emergency Stop Button is red in color and is used to shutdown the engine only in an emergency situation. It should not be used for normal engine stopping.Reset And Check Emergency Stop Switches
If the emergency stop switch was used to shut down the engine, it will be necessary to reset the switch. To reset the switch, pull out and rotate the button in the direction shown. If the emergency stop button was used to shutdown the engine it will be necessary to reset the air shutoff (if equipped).Before starting the engine, correct the problem that necessitated the emergency stop.
