Daily Gun Care, Flushing, and Cleaning

14. Be sure to install a new seat gasket (12b). Trigger

the gun while you install the seat housing (13) with
the gun tool (36). Tighten the housing securely to
obtain a good seal. Refer to Fig. 16 for recom-
mended torque values. When properly tightened,
the flange will bottom out on the gun.

15. Install the air cap retaining ring (18), air cap (14),

and spray tip (33).
