Oil the piston assembly, then wipe the front faces of the seal and piston
dry. Clean and lightly lubricate the body tube bore - do not over lubricate.
Refit the piston assembly to the body tube assembly, ensuring their
loading lever slots are aligned with one another.
Important Note.
The lip of the piston seal is an interference fit in the body
tube. As the piston assembly is pushed down the body tube, take care not to
damage the piston seal lip as it passes over body end plug pin holes, safe
clearance slot, trigger mechanism slot hidden by the cage and the loading
lever slot.
To minimize the risk of damage, deflect inwardly the portion of lip
exposed through the holes and slots using a blunt instrument e.g. the blade of a
screwdriver (fig. 11).
