This service guide shows how to replace the piston sleeve and chest plate on PRESTAN Professional Adult and Child manikins. Tools needed include a small slotted (flathead) screwdriver and a Phillips screwdriver; steps include removing the old chest plate and screw, opening the wire cover, and working through the piston sleeve and related hardware so the compression mechanism moves freely again. Diagrams call out the chest plate, piston sleeve, and wire routing details. Use this procedure when compressions feel binding, or the chest plate is damaged; then verify smooth piston travel before returning the manikin to class.
