Daily Gun Care, Flushing, and Cleaning
CAUTION
Trigger the gun whenever you tighten or remove the
diffuser (5). This keeps the needle ball away from the
seating surface and prevents the seat from being
damaged.
9. If it is necessary to remove the diffuser (5) to clean,
trigger the gun while you remove the diffuser with
the gun tool (30).
10. Dip the end of a soft-bristle brush into a compatible
solvent. Do not continuously soak the brush's bris-
tles with solvent and do not use a wire brush.

12. Scrub the air cap retaining ring (6), air cap (21), dif-
fuser (5), and spray tip (33) with the soft-bristle
brush. To clean out air cap holes, use a soft tool,
such as a toothpick, to avoid damaging critical sur-
faces. Blow air through the spray tip to ensure the
orifice is clean. Clean the air cap and spray tip daily,
minimum. Some applications require more frequent
cleaning.
