Graco Inc 3A0149C important safety instructions Air Line, Fluid Line

Air Line

1.Install an air filter (A) on the gun air line to ensure a dry, clean air supply to the gun. Dirt and moisture can ruin the appearance of your finished workpiece. See FIG. 1.

2.Install an air pressure regulator (C) on the gun air line to control air pressure to the gun.

3.Install an air shutoff valve (B) on the gun air line and on the pump air line, to shut off air to the gun.

4.Use a 3/16 in. (5 mm) I.D. or larger air hose to mini- mize excessive pressure drop in the hose.

NOTE: The gun air inlet has a 1/4-18 npsm (R1/4-19) compound male thread that is compatible with NPSM and BSP female swivel connectors.

5.Connect the air hose (G) to the 1/4 npsm gun air inlet. See FIG. 2.

Installation

Fluid Line

•Before connecting the fluid line, blow it out with air and flush it with solvent. See Flushing and Clean- ing, page 14. Use solvent which is compatible with the fluid to be sprayed.

•If better control of fluid pressure is needed, install a fluid regulator on the fluid line to better control fluid pressure to the gun.

1.Use a fluid filter to remove coarse particles and sed- iment, to avoid clogging the spray tip and causing finishing defects.

NOTE: Guns are equipped with a built-in 100 mesh fluid filter to provide final filtering just before spraying.

2.Connect the fluid hose (F) to the gun fluid inlet. See FIG. 4. If desired, install a fluid swivel connector (189018) at the gun inlet for best maneuverability. See Accessories, page 35.
