| Symptom | Remedy |
|---|---|
| Engine exhaust in an enclosed area | Start the engine and operate it in a well ventilated area. Vent the engine exhaust to the outside if started in an enclosed area. |
| Engine overheating or accelerated wear | Stop the engine according to the procedure described in the Operation and Maintenance Manual, 'Engine Stopping' topic (Operation Section). Do not use the Emergency Stop Button for normal stopping. Correct any problem that caused an emergency stop before restarting. |

Except for an overspeed shutdown, the monitoring system can be overridden. |
| Improper grounding of the engine electrical system | Proper grounding is necessary for optimum performance and reliability. Use an engine-to-frame ground strap with a direct path to the battery. Ensure all grounds are tight and free of corrosion. |
