4. Replace the air ngers by pushing in at the back side.

Remember to replace them according to the numbers

marked on them when they were removed. They must

go back in the same way they came out.

IMPORTANT: When inserting ngers the tab on

the outer plate must be in the groove as shown

in Figure 4-18. There is a blocking tab on the

outside of the groove which will prevent inserting

the nger in the groove if the outer plate is moved

away from the ange of the nger manifold.
