Inject starting aid (ether), only while cranking the engine, or after initial start-up, until the engine is running smoothly. Use sparingly, excessive ether without cranking can cause piston and ring damage. Wait approximately two seconds before injecting again. Use ether for cold starting purposes only. After every 30 seconds of engine cranking, allow two minutes for starting motor to cool before cranking again. Turbocharger damage can result, if the engine rpm is not kept low until the engine oil light/gauge verifies the oil pressure is sufficient. |

For starting below −18°C (0°F), the use of cold weather starting aids is recommended. One of the following may be required.
- A coolant heater
- A fuel heater
- A jacket water heater
- Extra battery capacity
At temperatures below −23°C (−10°F), consult your Caterpillar dealer. For additional information, refer to the Special Publication, SEBU5898, "Cold Weather Recommendations".
