Air Line; Fluid Line - Graco 288844 Instructions Manual

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 F . 1.
IG
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.
The gun air inlet has a 1/4-18 npsm (R1/4-19) com-
pound 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 F . 2.

Fluid Line

• Before connecting the fluid line, blow it out with air
and flush it with solvent. Use solvent which is com-
patible 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.
Guns are equipped with a built-in 100 mesh fluid fil-
ter to provide final filtering just before spraying.
2. Connect the fluid hose (F) to the gun fluid inlet. See
F . 4. If desired, install a fluid swivel connector
IG
(115898) at the gun inlet for best maneuverability.
See Accessories, page 33.
