ROLLER 4432503 - Caterpillar

Initial Start-up
Use the following procedure to manually start a generator set for the first time. Use the following procedure to manually start a generator set that has been out of service for a long time for maintenance.Note: The generator set may be stopped at any time by pressing the Emergency Stop Push button or turning the Control Switch to STOP.Note: Prior to restarting the set, the emergency stop push button must be released by turning the emergency stop push button clockwise. The fault lamp must also be reset by pressing the lamp test switch.
Prime the lube oil system by first removing one wire from the fuel solenoid or the actuator. This prevents the engine from starting. Turn the Control Switch to RUN. The engine will automatically crank. When oil pressure is registered on the gauge, turn the Control Switch back to the OFF position and reconnect the wire to the fuel solenoid or the actuator. If the oil pressure does not rise after three automatic attempts to crank the engine and illumination of the "FAIL TO START" fault lamp, investigate the reason for lack of oil pressure prior to further attempts to crank the engine.
Prime the fuel system with the hand priming pump and bleed the entrapped air from the fuel filter. Refer to this Operation and Maintenance Manual, "Fuel System - Prime".
Start: Ensure that the emergency stop push button and any remote stop buttons are released. Turn the Control Switch to RUN. For a cold engine, push in the switch for the preheat system for 15 seconds and then turn the control switch to the RUN position. Continue to press the switch for the preheat system until the engine fires. The engine will automatically crank up to three times until the engine begins to run. If the engine fails to start, the control system will be inhibited and the "FAIL TO START" indicator will illuminate. If this happens determine the cause of the failure to start.
Shut down the generator set after approximately one minute of engine. Press the emergency stop push button or turn the Control Switch to the STOP position. Remove the radiator cap and wait for five minutes. This will allow any trapped air to escape. Check the coolant level and refill the radiator,if necessary.Note: A newly filled coolant system can have air locks that must be cleared by running the engine for a short time and the system refilled prior to extended running of the engine.
Restart the engine. Use the following procedures in step 5 above.
Check for any abnormal noise or vibration.
Check the control panel for indications of abnormal operation. Check for an abnormally high temperature or an abnormally low oil pressure. The oil pressure should be in the normal range within about 10 seconds of starting.
Check the control panel for output voltage and frequency. The voltage is factory set and the control panel should indicate the rated voltage. Adjustments should only be carried out by a qualified technician. Two means of voltage adjustment
