See Figure 6-8.

1. Roll the new air piston seal lip on a flat surface to form the seal lip (6).

The piston seal lip must hang down toward the film coater, as shown

in Figure 6-8, so the piston will fit properly in the piston insertion tool.

2. Coat the seal area of the piston insertion tool with Parker O-ring

lubricant or an equivalent lubricant.  Orient the piston assembly as

shown in Figure 6-8, then install it into the piston insertion tool.  Make

sure the entire assembly fits into the tool.

3. Make sure the air piston seal is round.  There should be no gaps or

folds between the piston insertion tool bore and the lip of the piston

seal.  Replace the piston seal if necessary.
