•
Container to catch used oil

Funnel

1-L container of Anderol vacuum oil, type GS 495
To replace the roughing pump oil:
1. Gas ballast the roughing pump for 1 hour to reduce the oil viscosity (see
).
Rationale:
Gas ballasting helps to circulate and mix the oil through the
pump before draining.
2. Vent and shut down the instrument (see the mass spectrometer’s online
Help for details).
3. Allow the roughing pump to cool.
4. Place the container for used oil under the pump’s drain plug.
Warning:
The roughing pump oil can be irritant, or
contaminated with biohazardous or toxic analyte
accumulated during normal operation. Always wear
chemical-resistant, powder-free gloves when adding or
replacing oil.
Warning:
To avoid burn injuries, take great care while working
with the roughing pump; it can be hot.
