Troubleshooting and Maintenance Manual 93
Maintaining the Vacuum System
Periodic maintenance
As listed in Table 6, some maintenance tasks for the vacuum system must be
performed periodically. These include:
• Checking the foreline pump fluid (every week)
• Checking the calibration vial (every 6 months)
• Replacing the foreline pump oil (every 6 months)
• Tightening the foreline pump oil box screws (first oil change after
installation)
Failure to perform these tasks as scheduled can result in decreased
instrument performance. It can also result in damage to your instrument.
Other procedures
Tasks such as replacing an ion vacuum gauge should be performed only when
needed. See Chapter 2, “General Troubleshooting” on page 25 and see the
online help in the MassHunter Workstation software for symptoms that
indicate this type of maintenance is required.
More information is available
If you need more information about the locations or functions of vacuum
system components, see “Vacuum System” on page 129.
Most of the procedures in this chapter are illustrated with video clips on the
7000 Series MS User Information DVD.
