54 SEBU8726-03 Operation Section Engine Starting Engine Starting i05365825 Cold Weather Starting i03648917 Before Starting Engine Perform the required daily maintenance and other periodic maintenance before the engine is started. Inspect the engine compartment. This inspection can help prevent major repairs at a later date. Refer to the Operation and Maintenance Manual, “Maintenance Interval Schedule” for more information. Do not use aerosol types of starting aids such as ether. Such use could result in an explosion and personal injury. The ability to start the engine will be improved at temperatures below −18 °C (0 °F) from the use of a jacket water heater or extra battery capacity.
Ensure that the engine has an adequate fuel supply. When Group 2 diesel fuel is used, the following items provide a means of minimizing starting problems and fuel problems in cold weather: Engine oil pan heaters, jacket water heaters, fuel heaters and fuel line insulation. Open the fuel supply valve (if equipped). NOTICE All valves in the fuel return line must be open and fuel supply lines must be open. Damage to the fuel sys- tem can occure if fuel lines are closed with the engine in operation. Use the procedure that follows for cold weather starting. Note: Do not adjust the engine speed control during start-up.
The electronic control module (ECM) will control the engine speed during start-up. If the engine has not been started for several weeks, fuel may have drained from the fuel system. Air may have entered the filter housing. Also, when fuel filters have been changed, some air pockets will be trapped in the engine. In these instances, prime the fuel system. Refer to the Operation and Maintenance Manual, “Fuel System - Prime” for more information on priming the fuel system. Also, check that the fuel specification is correct and that the fuel condition is correct. Refer to the Operation and Maintenance Manual, “Fuel Recommendations”. 1. Disengage any driven equipment. Note:
During key ON, the indicator lamps will be illuminated for 2 seconds in order to check the lamp operation. If any of the indicator lamps do not illuminate check the bulb. If any indicator lamps stay illuminated or flash, refer to Troubleshooting, “Indicator Lamp Circuit - Test”. 2. Turn the keyswitch to the RUN position. Leave the keyswitch in the RUN position until the warning light for the glow plugs is extinguished. Engine exhaust contains products of combustion which may be harmful to your health. Always start and operate the engine in a well ventilated area and, if in an enclosed area, vent the exhaust to the outside. 3.
When the warning light for the glow plugs is extinguished, turn the keyswitch to the START position in order to engage the electric starting motor and crank the engine. Note: The operating period of the warning light for the glow plugs will change due to the ambient air temperature. Do not start the engine or move any of the controls if there is a DO NOT OPERATE warning tag or similar warning tag attached to the start switch or to the controls. NOTICE Do not engage the starting motor when flywheel is turning. Do not start the engine under load. Reset all of the shutoffs or alarm components. Ensure that any driven equipment has been disengaged.
Minimize electrical loads or remove any electrical loads. 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. 4. Allow the keyswitch to return to the RUN position after the engine starts.
