strokes. Air pressure gage (3) should indicate 60 psig .Operator should feel resistance from air
compression with each stroke, and pressure should be maintained within 2 psig for one
minute.
a. If little resistance is felt, air pressure system has air leak. Report on DA Form 2404 to
your supervisor.
