Connect the Air Line
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 (O) 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 and can cause the gun to
malfunction.
3. Install a bleed-type air regulator (G) on the pump
and gun air supply lines to control air pressure to the
pump and gun.
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).
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.
WARNING
Pressurized Equipment 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 serious injury, including splashing
fluid in the eyes or on the skin.
