Preventive Maintenance
Schedule
The following schedule is only a general guideline.
Therefore, you must establish your own preventive
maintenance schedule based on the operating condi-
tions and application of your specific system. These cri-
teria will determine how often maintenance, repair, and
rebuild is needed.
Establish a preventive maintenance schedule by record-
ing when and what kind of maintenance is needed.
Then determine a regular schedule for checking your
system.
Repair technicians must conform to the prescribed
maintenance intervals to prevent malfunctions and
unscheduled production interruptions.
For components or procedures that are not listed in this
table, contact your Graco distributor.
Table 1. General Guidelines for a Preventive Maintenance Schedule
