The vacuum pump is shipped without oil in the reservoir. Before starting the unit, you
must fill the pump with oil. Two 16-ounce (472 milliliters) bottles of oil are included with
your unit.
11. Remove the black plastic plug from the pump’s oil fill port. Attach the flexible spout

pump.

13. Press SHIFT/RESET and ENTER at the same time, then press “VACUUM.”
The vacuum pump will start and run continuously. While the pump is running, pour
oil into the pump’s oil fill port until the level of oil is even with the line of the pump
reservoir sight glass. Replace the black plug on the oil fill port.
14. Let the pump run for about five (5) minutes to remove any air from the unit.
15. To turn off the pump, press HOLD/CONT. Then press SHIFT/RESET to exit
the diagnostics mode.
16. Disconnect the blue 96” hose from the filter housing fitting on the unit. Disconnect
the red 96” hose from the air purge fitting on the tank.
17. Connect the 36” yellow hose to the air purge fitting on the tank.

Before using a new tank, you must purge its nitrogen charge and pull it into a vacuum.
