* The frequency of maintenance indicated for these parts is a general guideline only. Actual
cleaning regimen may be infrequent, dependant on local lab/workload variables.
Refer to the Agilent 7500 Series Maintenance DVD for instructional videos on how to perform all
maintenance tasks. It is easier to schedule maintenance if you keep a log of the instrument
readings for each analysis. Generating a tuning report daily is also strongly recommended. The
“Maintenance LogBook” feature explained later in this chapter has a similar function.
