LOCK 8P0484 - Caterpillar

Engine exhaust contains products of combustion which may be harmful to your health. Always start and operate the engine in a well ventilated area and, if in an enclosed area, vent the exhaust to the outside.
Prelubrication
The electronic control module (ECM) will operate the prelube pump under these conditions:
The "ENGINE PRELUBE DURATION" parameter is programmed to a value that is greater than zero.
The engine control switch is turned to the "MAN.START" position. Alternatively, the engine control switch is in the "AUTO" position when the remote start/stop initiate contact closes.The prelube pump will supply oil under pressure to the engine until one of the following conditions occurs:
The oil pressure closes a pressure contactor.
The programmed "ENGINE PRELUBE DURATION" expires.Engine cranking will begin after the prelube pump stops.Automatic Starting
When the engine is in the AUTOMATIC mode, the engine can start at any moment. To avoid personal injury, always remain clear of the the engine when the engine is in the AUTOMATIC mode.
For automatic starting, the engine control switch must be in the "AUTO" position. The engine will automatically start when the remote start/stop initiate contact closes.Manual Starting
For initial start-up of a new or rebuilt engine, and for start-up of an engine that has been serviced, make provision to shut the engine off should an overspeed occur. This may be accomplished by shutting off the air and/or fuel supply to the engine.
Do not start the engine or move any of the controls if there is a "DO NOT OPERATE" warning tag or a similar warning tag attached to the start switch or the controls.Ensure that no one will be endangered before the engine is started and when the engine is started.
Perform all the procedures that are described in this Operation and Maintenance Manual, "Before Starting Engine" topic (Operation Section).
Ensure that the marine transmission is disengaged.
Do not engage the starting motor when flywheel is turning. Do not start the engine under load.If the engine fails to start within 30 seconds, release the starter switch or button and wait two minutes to allow the starting motor to cool before attempting to start the engine again.
Note: If the optional prelube is used, the prelube pump will operate before cranking begins.
To start the engine, turn the engine control switch to the "MANUAL START" position.The ECM will allow the engine to be operated at rated rpm when the oil pressure sensors indicate that the oil pressure is sufficient.Overcrank
The crank cycle is the amount of time for engagement of the starting motor. This event also includes the amount of time for cooling of the starting motor between crank cycles. The crank cycle and the number of crank cycles are programmable.If the engine does not start within the number of crank cycles that are programmed, the fuel system is disabled. The "OVERCRANK" indicator will illuminate to warn the operator of an overcrank.If an overcrank occurs, the ECM must be reset before starting can be attempted. To reset the ECM, turn the engine control switch to the "OFF/RESET" position.Starting the Engine
