Before Starting
You can perform much of the maintenance required by your MS. For your safety,
read all of the information in this introduction before performing any
maintenance tasks.
Scheduled maintenance
Performing common maintenance tasks when scheduled can reduce operating
problems, prolong system life, and reduce overall operating costs. (See
Table 14 .)
Keep a record of system performance (tune reports) and maintenance
operations performed. This makes it easier to identify variations from normal
operation and to take corrective action.
