Connect the Air Line

WARNING

Electric Shock Hazard

To reduce the risk of electric shock or other serious injury, the air supply hose must be electrically connected to a true earth ground. Use only Graco Grounded Air

Supply Hose.

1.Connect the Graco Grounded Air Supply Hose (R) between the air supply line and the gun's air inlet

(V). The gun air inlet fitting has a left-hand thread. Connect the air supply hose ground wire (Q) to a true earth ground.

2.Install an air line filter/water separator (D) on the air line to ensure a dry, clean air supply to the gun. Dirt and moisture can ruin the appearance of your finished workpiece and can cause the gun to mal- function.

Installation

3.Install a bleed-type air regulator (G, O) on the pump and gun air supply lines to control air pres- sure to the pump and gun.

WARNING

Fluid Injection Hazard

The bleed-type air valve (E) is required in your system to relieve air trapped between

the valve and the pump after the air regula- tor is shut off. Trapped air can cause the

pump to cycle unexpectedly, which can result in seri- ous injury, including fluid injection and splashing fluid in the eyes or on the skin.

4.Install a bleed-type air valve (E) on the pump air line to shut off air to the pump. Install an additional bleed-type air valve (C) on the main air line (A) to isolate the accessories for servicing.

5.Install an air shutoff valve ( P) on each gun air sup- ply line to shut off air to the gun(s).

WARNING

Fluid Injection Hazard

To reduce the risk of serious injury due to component rupture, including fluid injec- tion, pump pressure must be limited by the pump air regulator. Do not rely on the gun fluid regulator to limit the fluid pressure to the gun.

The fluid supply pump must be prevented from pro- ducing a fluid pressure greater than the 3000 psi (21 MPa, 210 bar) Maximum Working Fluid Pressure of the gun. For example, the air supply pressure to a 30:1 ratio pump must not exceed 100 psi (0.7 MPa, 7 bar).

Connect the Exhaust Tube

Press the exhaust tube (38) onto the barbed adapter on the bottom of the gun handle. Secure the tube with the clamp (39).
