7. Using the nut driver, loosen the jet and pull it straight out. You may need to
use the forceps to grasp the jet.
8. Inspect the jet sealing surface for scratches. You should see a ring around
the sealing surface; other scratches are unacceptable.
9. Inspect the jet tube to make sure it is not bent or crimped. Inspect the jet
for contamination or pieces of broken column by holding it up to a light
and looking through it. If no contamination is present, the tube will be
clear.
Caution Do not over-tighten the jet! Over-tightening may permanently deform and
damage the jet, the detector base, or both.
