How to Examine Compressed Air Mechanisms
Your machine has one or more mechanisms that use compressed air for movement. To
examine a compressed air mechanism, look at the mechanism and listen to it in operation. Do
not touch the mechanism or put your hand in the machine. Usually you can see movement
directly or on a position indicator. Frequently, you can hear a valve open and close. When a
signal from the controller to operate the mechanism occurs, the air pressure must increase
sufficiently before movement occurs. When the signal stops, the system must release the
compressed air. You can usually hear the sound of the exhaust air for a short time.
When a compressed air mechanism operates correctly, its time of movement is usually less than
two seconds. The movement is smooth. It does not shake, change speed, or stop in the middle
of travel. A mechanism that does not operate correctly will cause unsatisfactory performance. If
the mechanism does not operate correctly and you cannot repair the problem, speak to your
dealer or Milnor. Possible causes are as follows:
• a blockage or a leak in the air tube,
• a worn pilot air valve,
• worn components in the mechanism,
• air pressure supplied to the machine is not sufficient,
• a component used to remove contamination from the air line is clogged,
• a quick exhaust valve or muffler is clogged,
• on machines with an air line lubricator, a malfunction or incorrect adjustment prevents
sufficient lubrication.
