b. During testing, PMCS, and storage it is necessary to exercise hydraulic components to make sure they are operating

properly. Refer to Appendix J for instructions on exercising the recoil system using the recoil exerciser.

Periodic operation of hydraulic components is necessary to maintain packings and seals in operating position, to re-

plenish hydraulic fluid film on cylinder walls, to prevent rusting, corrosion, galling, and to prevent sticking or seizing of

the pistons in their cylinders.
