0320309 EVINRUDE RETAINING RING

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 ignites a controlled amount of fuel in order to provide heated inlet air for 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 Caterpillar dealer.
Turn the ignition switch to the ON position.
Move the throttle to the low idle 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.
When an air inlet heater is used, turn the ignition switch to the HEAT position. Maintain the HEAT position for 15 seconds.
Turn the ignition switch to the HEAT-START position in order to crank the engine. If the engine fails to start, turn the ignition switch to the HEAT position for 10 seconds. Turn the ignition switch to the HEAT-START position in order to crank the engine. Allow the ignition switch to return to the RUN position as soon as the engine starts.Note: Some applications may be equipped with a START button and a HEAT button instead of a key switch. If the control panel is equipped with buttons instead of a key switch, then use the following procedure:
Press the HEAT button for 15 seconds.
Maintain the hold on the HEAT button. Press the START button in order to crank the engine. If the engine fails to start, again press the HEAT button for 10 seconds. Press the START button in order to crank the engine. Immediately release the HEAT button.
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, 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.To minimize white smoke for cold weather starting, start the engine and allow the engine to idle for 30 seconds. Increase the rpm until the engine speed reaches 1200 rpm. Return the engine to low idle rpm.
Operate the engine at low load until all systems reach operating temperature. Check the gauges during the warm-up period.
