KIT-GASKET 6V3753 - 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.
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 fuel supply and/or the ignition to the engine.
Note: Using the "EMERGENCY STOP" button will shut off both the fuel and the ignition.Do not start the engine or move any of the controls if there is a "DO NOT OPERATE" warning tag or similar warning tag attached to the start switch or to the controls.Ensure that no one will be endangered before the engine is started and when the engine is started.Perform the procedures that are described in this Operation and Maintenance Manual, "Before Starting Engine" (Operation Section).Purging Unburned Gas
Unburned gas in the air inlet and exhaust system may ignite when the engine is started. Personal injury and/or property damage may result.Before starting an engine that may contain unburned gas, purge the unburned gas from the air inlet and exhaust system. Refer to the topic on purging unburned gas in the "Starting the Engine" section.
The following events cause unburned gas to remain in the air inlet and in the exhaust manifold:
Emergency stop
Engine overspeed
The engine control is set to the STOP mode and the gas shutoff valve does not close.
Unsuccessful successive attempts to start the engineUnburned gas may remain in the air inlet and exhaust system after several unsuccessful attempts to start the engine. The unburned gas may increase to a concentration that may ignite during a successive attempt to start the engine.Perform the following procedure in order to purge the unburned gas:
Using either the messenger display, or Cat Electronic Technician (ET), verify that the value of the "Engine Purge Cycle" parameter is equal to 10 seconds less than the value of the "Crank Cycle" parameter.
Set the engine control to the START mode. The engine will crank for the "Engine Purge Cycle" time. Then, the gas shutoff valve will be energized and the ignition will be enabled. The engine will start.
Continue with your previous procedure. 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.
If the engine control switch is in "AUTO", the engine will automatically start when the remote start/stop initiate contact closes.Parameters for the Start/Stop Control
Driven Equipment
Start-up is delayed until the switch for the driven equipment indicates that the driven equipment is ready.Purge Cycle
Note: The engine uses an energize-to-run system. The gas shutoff valve must remain energized in order to supply fuel to the engine.The purge cycle allows any unburned fuel to exit through the exhaust before the engine is allowed to fire.The purge cycle occurs under these conditions:
The gas
