10. Run the first flush cycle.

    1. Start the engine. Release the brake.

    2. Set the travel speed control to low speed. In order to rotate the drum, move the propel control.

    3. Set the vibratory amplitude control to the LOW position.

    4. Turn on the vibratory system. Run the vibratory system for 5 seconds. Turn off the vibratory system. Repeat the cycle for three minutes.

       Note: For each cycle, do not run the vibratory system more than 5 seconds.

    5. Stop the drum. Position the drum in order to drain the housings.

11. Install the transfer cart. Pump the oil out of the housings. Cycle the oil through the filter for 30 minutes. Cycle the oil until the oil is cleaned to a rating of ISO 18/13 or better.

12. Install the transfer cart to the housings. Pump the oil into the housings. For the second cycle, repeat steps 6 through 9. After the second cycle, take an oil sample before filtering the oil. No further flushing is necessary, if the oil sample rating is equal or lower than ISO 19/16. Another flushing is necessary, if the oil sample rating is higher than ISO 19/16.

13. When the flushing is complete, rotate the drum to the position in order to drain the housings. Remove the valve and fitting assembly. Drain as much of the oil as possible.

14. Rotate the drum until the fill/drain plug is at the top. Remove the level check plug. Fill the drum to the correct level. Refer to the Operation and Maintenance Manual, "Lubrication Specifications and Refill Capacities".

    Note: The new oil must have a oil sample rating that is equal or lower than ISO 18/15.
