Before Starting - HP 5973 Hardware Manual

Before starting

You can perform much of the maintenance required by your MSD. For your
safety, read all of the information in this introduction before performing any
maintenance tasks.
Some parts of the MSD require regularly scheduled maintenance
Common maintenance tasks are listed in Table 4. Performing these tasks
when scheduled can reduce operating problems, prolong system life, and
reduce overall operating costs.
Keep a record of system performance (tune reports) and maintenance
operations performed. This makes it easier to identify variations from nor-
mal operation and to take corrective action.
