4. Disconnect the vacuum pump hose from the top of the vacuum pump.
5. Grasp the handle on top of the vacuum pump and lift it out of the analyzer; place the
vacuum pump on a work table.
6. Drain the used oil:
a. Place a waste container under the drain fitting.
b. Remove the plug from the drain spout.
c. Allow the oil to drain into the waste container.
Badly contaminated fluid requires flushing of the pump once or twice with fresh
fluid to wash out contaminants.
d. Replace the drain plug.
7. Remove the Oil-fill plug; add fresh fluid to the oil-fill port until the level is midway
between the two indicator lines.
Adding fluid above the midway position on the fluid level indicator may cause fluid
to splash into the vacuum hoses and leak from the internal vacuum pump.
