clearance while applying and releasing compressed air
(392 kPa, 4.0 kgf/cm
2, 57 psi).
Pack clearance:0.60−0.82 mm (0.02362−0.03228 in.)
If the pack clearance is less than the minimum, parts may have
been assembled incorrectly, so check and reassemble again.
If the stroke is not within standard, select another flange.
