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. |

|
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. |
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).
The following events cause unburned gas to remain in the air inlet and in the exhaust manifold:
- Emergency stop
- Engine overspeed
- Unsuccessful successive attempts to start the engine
Unburned 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:
- Turn the manual gas shutoff valve to the CLOSED position.
- Disable the ignition by grounding the "G" lead in the ignition harness.
- Turn the engine control switch to the START position. Crank the engine for one full crank cycle in order to purge the unburned gas.
- Turn the engine control switch to the OFF/RESET position.
- Enable the ignition by disconnecting the "G" lead from ground.
- Turn the manual gas shutoff valve to the OPEN position.
- Continue with your previous procedure.

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 the "AUTO" position, the engine will automatically start when the remote start/stop initiate contact closes. The engine will accelerate to rated rpm when the oil pressure is sufficient.
- Ensure that fuel is supplied to the engine.
- Ensure that the main circuit breaker is open.

NOTICE 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.

- Allow the engine to idle for three to five minutes. The engine speed should stabilize at low idle rpm. Check all of the pressure gauges. Inspect the engine for leaks and listen for unusual noises. When all systems are normal, the rpm may be increased.
| Rated RPM And Low Idle RPM | |||||
| Rated rpm | 1000 | 1200 | 1400 | 1500 | 1800 |
| Low idle rpm | 700 | 900 | 1000 | 1000 | 1200 |
Note: If the cycle crank feature is enabled, the Status Control Module (SCM) will attempt to start the engine for the programmed period. If the engine fails to start within the programmed period, the SCM will execute an overcrank fault. The "OVERCRANK" indicator on the Remote Control Panel (Status) will illuminate. The SCM must be reset before the engine can be started. Turn the engine control switch to the "OFF/RESET" position.
If the engine fails to start after cranking for 30 seconds, stop cranking. Perform the following procedure:
- Turn the engine control switch to the "OFF/RESET" position.
- Turn the gas supply OFF.
- Allow the starting motor to cool for two minutes. Crank the engine for approximately 15 seconds in order to disperse any unburned gas from the engine and the exhaust system.
- Allow the starting motor to cool for two minutes. Turn the gas supply ON. Repeat the starting procedure.
