Use the 8-mm Allen wrench to fit and tighten the roughing pump's oil filler plug.
Tips:
•
When the oil filler plug is tightened, the plug seals by means of an O-ring. Compression
is controlled by the O-ring groove depth in the plug. Overtightening does not improve
the plug seal; it merely makes the plug difficult to remove.

To maintain pump performance, use only Anderol vacuum oil, type LVO200.
To avoid oil leakage, and consequent damage to the pump, when refitting
the plug is not cross-threaded;
the O-ring is not pinched;
the plug is not overtightened.
The oil level drops slightly during the first month of operation.
The oil darkens in color over time.
After running the pump for 12 to 48 hours, it is common to see a few drops of oil
near the filler plug. Excess oil around the lip of the filler plug will run down and drip
off the pump when the pump reaches operating temperature.
When the pump begins to run at normal operating temperature, the spilled oil
produces a slight odor.
