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.

5.Increase the pressure slowly. Point the gun down into a grounded metal container, and flush the gun with solvent until all traces of fluid are removed from the gun passages.

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.
