NOTE: Solvent left in gun air passages could result in a
poor quality paint finish. Do not use any cleaning
method which may allow solvent into the gun air
passages.
• Do not point gun up while cleaning.
• Do not wipe the gun with a cloth soaked in solvent;
wring out the excess.
• Do not immerse the gun in solvent.
• Do not use metal tools to clean the air cap holes;
this may scratch them. Scratches may distort the
spray pattern.
1. Follow the Pressure Relief Procedure, page 14.
2. Shut off the gun fan and atomizing air.
To avoid serious injury from skin injection, do not put
your hand in front of the spray tip when removing,
installing, or maintaining the air cap and spray tip.

and spray tip (9).

10. 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.
11. With the gun pointed down, clean the front of the
gun, using the soft-bristle brush and solvent.
12. Scrub the air cap retaining ring (8), air cap (30), and
spray tip (9) with the soft-bristle brush. To clean out
air cap holes, use a soft tool, such as a toothpick, to
avoid damaging critical surfaces. 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.
