C. Reassembly of Air Fingers

1.Air fingers are made up of one inner plate, one outer plate and the finger housing manifold. Be sure to match up the markings (T1, T2, T3, etc.) on all the parts of the air fingers as you are reassembling.

Figure 4-14.

2.Reassemble the inner plate. Keep your fingers clear so you won’t pinch them. The inner plate of a finger will only go in one way because of its design.

3.Replace the outer plate by placing your hands flat on the top of the plate and pushing down. Keep your fingers clear so you won’t pinch them.
