SEBU8726-03 55 Operation Section Starting the Engine 5. Repeat step 2 through step 4 if the engine fails to start. 4. 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: After starting, the engine will be held at low speed. The time held at low speed will depend on ambient temperature and time since last run. The procedure is in order to allow the engine systems to stabilize. The engine should not be “raced” in order to speed up the warm-up process. Note: The operating period of the warning light for the glow plugs will change due to the temperature of the engine. 6.
Allow the engine to idle for 3 to 5 minutes, or allow the engine to idle until the water temperature indicator begins to rise. When idling after the engine has started in cold weather, increase the engine rpm from 1000 to 1200 rpm. This operation will warm up the engine more quickly. Maintaining an elevated low idle speed for extended periods will be easier with the installation of a hand throttle. Allow the white smoke to disperse before proceeding with normal operation. NOTICE 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. 5. Allow the keyswitch to return to the RUN position after the engine starts. Ensure that all warning lamps are off. 7. Operate the engine at low load until all systems reach operating temperature. Check the gauges during the warm-up period. 6. Repeat step 2 through step 5 if the engine fails to start. 7. After starting, the engine will be held at low speed. The time held at low speed will depend on ambient temperature and time since last run.
The procedure is in order to allow the engine systems to stabilize. i05365826 Starting the Engine Note: Do not adjust the engine speed control during start-up. The electronic control module (ECM) will control the engine speed during start-up. 8. If the engine will not start, refer to Troubleshooting, “Engine Cranks but Does Not Start” Starting the Engine i06092747 Starting with Jump Start Cables (Do Not Use This Procedure in Hazardous Locations that have Explosive Atmospheres) 1. Disengage any equipment that is driven by the engine. 2. Turn the keyswitch to the first position power on. Check that the low oil pressure lamp is on solid.
If the lamp is on solid, the engine start sequence can continue. If the lamp is flashing, and engine oil change is required. Refer to this Operation and Maintenance Manual, “Engine Oil and Filter - Change” for more information. 3. Turn the keyswitch to the RUN position. Leave the keyswitch in the RUN position until the warning light for the glow plugs is extinguished. The connection of battery cables to a battery and the disconnection of battery cables from a battery may cause an explosion which may result in in- jury or death. The connection and the disconnec- tion of other electrical equipment may also cause an explosion which may result in injury or death.
The procedures for the connection and the dis- connection of battery cables and other electrical equipment should only be performed in a nonex- plosive atmosphere. Note: During the key on, the indicator lamps will be illuminated for 2 seconds in order to check lamp operation. If any of the lamps do not illuminate, check the bulb. If the fault remains refer to Troubleshooting, “Indicator Lamp Circuit - Test”.
