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.
Note: When electric power is cycled, the electronic thermostat cycles. This process makes a unique sound that is a normal sound for a start-up.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 controls.Ensure that no one will be endangered when the engine is started.
Perform all of the procedures that are described in this Operation and Maintenance Manual, "Before Starting Engine" (Operation Section).
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.
To start an engine with the control panel, press the "Start/Stop" switch.For additional information on the control panel, refer to this Operation and Maintenance Manual, "Control Panel".Starting the Engine After an Overhaul or Major Repair
Use the following guidelines for operation and maintenance after an overhaul or a major repair. This procedure will ensure that the engine is functioning correctly. The procedure for start-up requires approximately 1 hour and 45 minutes.
Perform the procedures that are described in this Operation and Maintenance Manual, "Before Starting Engine" topic (Operation Section).
Operate the jacket water heaters and the prelube pump. Allow the lubricating oil to circulate for 1/2 hour.
During prelube pump operation, use the barring device to rotate the crankshaft for a minimum of four revolutions.
Start the engine. Operate the engine at low idle rpm for 15 minutes. Allow the engine temperature to rise. Check for the correct temperatures and pressures. Inspect the installation for leaks.
Do not apply the load. Increase the engine rpm to high idle rpm for 5 minutes. Check for the correct temperatures and pressures. Inspect the installation for leaks.
Shut off the engine. Remove the side covers. Measure the temperature of the bearings with a 123-6700 Laser Infrared Thermometer. Ensure that the large ends of the connecting rod bearings moves freely. Visually inspect the piston skirts, cylinder liners, and bearings for any abnormal signs such as flaking and/or scuffing. If the appearance of the components is satisfactory, install the side covers.
Start the engine. Operate the engine at low idle rpm for 5 minutes. Check for the correct temperatures and pressures. Inspect the installation for leaks.
The temperatures will not stabilize for some time because the engine will be operating without a load. To warm the engine up to "normal" operating
