(14).

CAUTION
Trigger the gun whenever you tighten or remove the
nozzle. This keeps the needle seat away from the
nozzle seating surface and prevents the seat from
being damaged.
10. Clean the air cap retaining ring, air cap, and fluid
nozzle with solvent.
11. Dip the end of a soft-bristle brush into a compatible
solvent. Do not continuously soak the brush's
bristles with solvent and do not use a wire brush.

13. Scrub the air cap retaining ring, air cap, and fluid
nozzle with the soft-bristle brush. To clean out air
cap holes, use a soft implement, such as a tooth-
pick, to avoid damaging critical surfaces. Clean the
air cap and fluid nozzle daily, minimum. Some
applications require more frequent cleaning. Do
not soak the air cap retaining ring in solvent for
prolonged periods of time.
