    Inspect all replacement parts, prior to installation, to detect any damage which might have occurred in ship- ment. • Use only genuine BRADEN replacement parts for optimum results. Never reuse expendable parts such as oil seals and O-rings. • Inspect all machined surfaces for excessive wear or damage . . . before reassembly operations are begun.
