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 fin-
ished workpiece and can cause the gun to malfunc-
tion.
WARNING
Skin Injection Hazard
To reduce the risk of serious injury due to
component rupture, including fluid injection,
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).

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

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).
