TURBOCHARGER GP 2269413 - Caterpillar

Do not crank the engine for more than 30 seconds. Allow the starter to cool for two minutes before cranking again. Turbocharger damage can result if the engine rpm is not kept low until the oil gauge display verifies that the oil pressure is sufficient.
Engine Starting with Ether Starting Aid (If Equipped)
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.
Follow Step 1 through Step 8 of the Engine Starting Procedure. A premeasured amount of ether will be automatically injected if the ambient conditions call for starting aid.
