TUBE AS 3906698 - Caterpillar

DO NOT USE ETHER (starting fluids) unless specifically instructed to do so. If the engine is equipped with an Air Inlet Heater (electrically or fuel ignited manifold heater), DO NOT use ether (starting fluids) at any time. The use could result in engine damage and/or personal injury.
An air inlet heater is installed in the air inlet manifold. The air inlet heater is an electrical device which warms the inlet air to aid in cold weather starting.Note: Startability will be improved at temperatures below 16°C (60°F) by the use of the air inlet heater. This will help reduce white smoke and misfire during start-up in cold weather.Startability will be improved at temperatures below -18°C (0°F) from the use of a cylinder block coolant heater or extra battery capacity.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, engine coolant heaters, fuel heaters and fuel line insulation.For temperatures below -23°C (-10°F), consult your dealer.

Turn the ignition switch (1) to the ON position.
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.
Push the air inlet heater switch (2) and hold the air inlet heater switch for 20 seconds. Turn the ignition switch to the START position in order to crank the engine. Crank the engine for 15 seconds or until the engine starts. If the engine fails to start, turn the ignition switch to the ON position and hold the air inlet heater switch for 10 seconds. Turn the ignition switch to the START position in order to crank the engine. Crank the engine for 15 seconds or until the engine starts. Run the engine at HIGH idle and move to LOW idle for warm-up.Allow the ignition switch to return to the RUN position as soon as the engine starts.
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.
Allow the engine to idle for three to five minutes. The engine should run at high idle smoothly before decreasing to low idle. Allow the white smoke to disperse before you proceed with normal operation.
Operate the engine at low load until all systems reach operating temperature. Check all gauges during the warm-up period.
