7. Pull out side seal cartridges (18).
8. Pull mix chamber (19) out rear of fluid housing.
Inspect for damage. Follow the Clean
Impingement Ports procedure, page 23.
9. Apply thin coat of lubricant to mix chamber (19).
Install mix chamber. Etched A and notch (N) must
be on same side as A on fluid housing. Mix chamber
is keyed to fit in fluid housing.
10. Carefully inspect side seal cartridge o-rings and
surfaces. Replace worn or damaged parts. Liberally
lubricate o-rings (18d, 18e) and reassemble. Press
on side seal (18c) to check proper spring (18b)
operation.
11. Lubricate and reinstall side seal cartridges (18).
12. Lubricate all threads and reinstall retaining ring (9).

13. Follow the Attach Front End procedure, page 29.
14. Connect air and trigger the gun a few times to check
for leaks. If either check valve pops out of its seated
position, there is a poor fluid seal on that side of the
mix chamber or side seal/cartridge components.
Correct the problem before attaching the fluid
manifold.
15. Attach fluid manifold. Connect air. Return gun to
service.
NOTICE
To prevent cross-contamination in the gun, do not

damage the sealing surfaces, block fluid passages,
and prevent gun function.
