TUBE AS 4415933 - Caterpillar

When using starting fluid (ether), follow the manufacturer's instructions carefully. Use the starting fluid sparingly and spray only while cranking the engine. Failure to do so could result in an explosion and/or fire and personal injury.
The optional ether starting aid is the only starting fluid system that is recommended on the engine.
The engine is designed to start without starting aids at temperatures greater than 13° C (55° F)When No. 2 diesel fuel is used, the following items provide a means of minimizing starting problems and fuel problems in cold weather: starting aids, engine oil pan heaters, jacket water heaters, fuel heaters and fuel line insulation.For temperatures below −18° C (0° F), consult your Cat dealer.Use the procedure that follows for cold weather starting.Note: If the engine has not been run for several weeks, fuel may have drained. Air may have moved into the filter housing. Also, when fuel filters have been changed, some air will be left in the filter housing. Refer to the Operation and Maintenance Manual, "Fuel System - Prime" for more information on priming the fuel system.
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.
Turn the ignition switch to the RUN position. Advance the throttle in order to supply fuel to the engine.
Excessive ether can cause piston and piston ring damage. Use ether for cold starting purposes only. Do not use excessive starting fluid while starting the engine. Do not use starting fluid after the engine is running.
If equipped, press the "STARTING AID" switch in order to improve cold weather starting. Release the "STARTING AID" switch when the engine starts. Use the starting fluid sparingly. Carefully follow the instructions of the OEM.
Oil pressure should rise within 15 seconds after the engine starts. Do not increase engine speed until the oil pressure gauge indicates normal. If oil pressure is not indicated on the gauge within 15 seconds, DO NOT operate the engine. STOP the engine, investigate and correct the cause.
Increase the engine rpm to approximately 1/4 of the full load rpm.
Allow the engine to idle for 3 to 5 minutes, or allow the engine to idle until the water temperature indicator begins to rise. The engine should run at low idle smoothly until speed is gradually increased to high idle. Allow the white smoke to disperse before proceeding with normal operation.
Operate the engine at low load until all systems reach operating temperature. Check the gauges during the warm-up period.
