Clean and Flush Gun

1.Perform Pressure Relief Procedure, page 18.

2.Shut off the gun fan and atomizing air.

3.Supply a compatible solvent to the gun fluid inlet.

4.Point the gun down into a grounded metal container, and flush the gun with solvent until all traces of paint are removed from the gun passages.

5.Perform Pressure Relief Procedure, page 18.

6.Disconnect the solvent supply.

7.Remove the air cap retaining ring and air cap.

NOTICE

Trigger the gun or remove the piston cap whenever you tighten or remove the noz- zle. This keeps the needle seat away from the nozzle seating surface and prevents the seat from being damaged.

8.Clean the air cap retaining ring, air cap, and fluid nozzle with solvent.

9.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.

10.With the gun pointed down, clean the front of the gun, using the soft-bristle brush and solvent.

11.Scrub the air cap retaining ring, air cap, and fluid nozzle with the soft-bristle brush (see FIG. 15). To clean out air cap holes, use a soft implement, such as a toothpick, to avoid damaging critical surfaces. Clean the air cap and fluid nozzle daily, minimum. Some applications require more frequent cleaning.
