Visually inspect the engine for oil leaks. If the oil level is good, restart the unit and verify the loss of oil pressure. Check the oil pressure sender. |
| LOW COOLANT LEVEL SHUTDOWN | Coolant level in the radiator is low. | Allow the engine to cool. Check the coolant level in the radiator. |
| HIGH COOLANT TEMPERATURE SHUTDOWN | Coolant temperature is 230°F (110°C) or more. | Check coolant level, remove any blockages, inspect hoses and components for leaks, check water pump belt tension, and load the unit to prevent overheating. |
