Danger. Stop the machine and remove the power supply from the equipment before performing
maintenance operations.
Important. All PM should be performed by an AIRSYS Authorized Service Technician (AAST) to
ensure that the manufacturer’s warranty is preserved .
General Operation Check
It is a good idea to compare the operation of the equipment with the results of the previous inspection.
Any differences in operating characteristics can then be easily identified.
A detailed and periodic visual inspection of the equipment and a general cleaning are both important to
ensure good operation. Before beginning the PM steps, the general system status should be verified by
looking at the areas outlined in this section.
Check Main Voltage
Check the following:
• The main voltage is within ±15% of the rated voltage required by the machine.
• The DC voltage is in normal range, if applicable. (36 -57VDC)
