• Funnel
• Leybonol LVO 200 vacuum pump oil
To add oil to the roughing pump:
1. Vent and power-down the mass spectrometer (see the mass spectrometer's online Help for
details).
Warning:
and mass spectrometer, disconnect the power cords for the mass spectrometer
and roughing pump from the main power source.
2. Disconnect the power cords for the mass spectrometer and the roughing pump from the
main power source.
3. Allow the oil to settle in the pump.
Warning:
To avoid personal contamination with biologically hazardous, toxic, and
corrosive materials, wear chemical-resistant, powder-free gloves when performing this
procedure.
Warning:
other components heated to high temperatures. Wait until the hot components
have sufficiently cooled before you handle them.
4. Use the 12-mm hex wrench to unscrew and remove the pump's oil filler plug.
5. Using the funnel, add Leybonol LVO 200 vacuum pump oil into the oil filler aperture until
the oil reaches the maximum level ("MAX"), as indicated in the pump's oil level sight glass.
Requirement:
Notice:
• Inspect the O-ring on the plug and verify that it is free of particles.
• Ensure that the plug is not cross-threaded.
• Do not overtighten the plug.
6. Use the 12-mm hex wrench to refit the oil filler plug.
Tip:
When the plug is tightened, it seals against an O-ring. Compression is controlled by
the O-ring groove depth in the plug. Increasing torque does not improve the plug seal. It
only makes the plug difficult to remove later.
7. Connect the power cords for the mass spectrometer and the roughing pump to the main
power source.
8. Power-up the mass spectrometer (see
