Operation Section Engine Starting

TM5-2430-200-10 55 Operation Section Engine Starting Operation Section Engine Starting 6. Remove locking pin (6) and lift cover (7) on the start switch. 7. Move the start switch from OFF position (11) to ON position (10). If start-aid indicator (8) comes on, wait until the indicator turns off (up to 30 seconds) before attempting to start the engine. 8. Move the start switch to START position (9). Hold the switch in START to crank the engine. The indicators will turn on to indicate the presence of any burned out bulbs. (Refer to “Operation section, Monitoring Systems and Cab Features, Blackout Light Switch” in this manual for a list of indicators which operate in the different blackout switch positions.) Release the engine start switch when the engine starts. NOTE: Do not push or hold the accelerator pedal down while cranking the engine. The ECM will automatically provide the correct amount of fuel to start the engine. 9. If the engine does not start after 15 to 30 seconds of cranking, release the engine start switch and move it to ON position (10) to allow the air inlet heater to operate. Wait approximately 30 seconds to allow the starting motor to cool before operating the starter again. Repeat Steps 7 and 8. NOTICE Do not keep the starting motor engaged for more than 30 seconds at a time. Wait 30 seconds to allow the starting motor to cool before trying again. If the engine does not start after three attempts, determine the cause of the malfunction. Pumping the accelerator pedal will not assist in starting the engine. Do not increase engine speed until the oil pressure indicates between 250 and 450 kPa (30 and 70 psi). The engine oil pressure indicator should go off and the oil pressure should raise within 15 seconds after the engine starts. If oil pressure is not indicated on the gauge within 15 seconds, do not drive the machine. Stop the engine, and report the problem to Unit Maintenance. Do not operate the machine until the problem has been corrected. NOTE: Applying a light load will help the engine reach normal operating temperature sooner. When idling in cool weather, the ECM may increase the engine speed to approximately 1000 to 1200 rpm. Do not race the engine to make the machine warm up more quickly. NOTE: The ECM will disengage the starter at 600 rpm. Holding the starter engaged after the engine has started will not damage the starter.
