drying unless the pressure is/has been reduced to 30 psi (2.11

kg/cm2) or less. When working with compressed air, always use

chip guards, eye protection, and other personal protective

equipment.

(2) Dry all parts with compressed air.

(3) Inspect inside of tube assembly (1). If cylinder has deep grooves, score marks, or is severely damaged,
