Introduction

Introduction
How the Electrostatic Air Spray
Gun Works
The air hose supplies air to the spray gun. Part of the air
operates the turbine and the rest of the air atomizes the
fluid being sprayed. The turbine generates power, which
is converted by the power cartridge to supply high voltage current to the gun’s electrode.
The pump supplies fluid to the hose and gun, where the
fluid is electrostatically charged as it passes the electrode. The charged fluid is attracted to the grounded
workpiece, wrapping around and evenly coating all surfaces.

Gun Overview
The electrostatic gun includes the following controls
(see FIG. 1.).
•

FLUID adjustment valve. Adjusts fluid rod travel.
Use only in low flow conditions, to reduce wear.

•

Fan AIR adjustment valve. Adjusts fan size and
shape.

•

Atomizing air RESTRICTOR valve. Restricts
atomizing air flow. Replace with plug (included) if
desired.

•

ES ON/OFF valve. Turns electrostatics ON (I) or
OFF (0).

•

ES INDICATOR (standard gun only). Green when
ES is ON (I).

Installation

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 (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 supply 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).

Connect the Fluid Line
1. Before connecting the fluid line (N), blow it out with
air and flush it with solvent. Use solvent which is
compatible with the fluid to be sprayed.
2. Install a fluid regulator (M) on the fluid line to control
fluid pressure to the gun.
3. Install a fluid filter (K) and drain valve (U) at the
pump outlet.

WARNING
Pressurized Equipment Hazard
The fluid drain valve (U) is required in your
system to assist in relieving fluid pressure in
the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may
not be sufficient. Install a drain valve close
to the pump's fluid outlet. The drain valve
reduces the risk of serious injury, including
splashing in the eyes or on the skin.

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 regulator 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.

309292V

4. Connect the fluid line to the 3/8 npsm gun fluid inlet
(W).
5. Before running any paint through the spray gun,
flush it out with a compatible solvent.

Packing Rod Repair
You may replace the packing rod as individual parts or
as an assembly. The assembly is pre-adjusted at the
factory for proper air lead and lag. The gun begins emitting air before the fluid is discharged and the fluid stops
before the air flow stops.
To adjust the lead/lag air flow:
1. Remove the spring (4) from the nut (E).
2. Use a hex wrench to hold the end of the packing
rod. Turn the nut (E) out to increase the lead/lag
time for the air flow. The recommended adjustment
is one half turn and not more than one full turn.
3. Apply thread-locking adhesive to fix the nut in the
new position.
Before installing the fluid packing rod into the gun barrel,
make sure the internal surfaces of the barrel are clean.
Remove any residue with a soft brush or cloth. Check
the inside of the barrel for marks from high voltage arcing. If marks are present, replace the barrel.

2. Fill the inner cavity of the spacer (26g**) with dielectric grease (40). Place the spacer on the fluid rod
(26h) in the direction shown. Generously apply
dielectric grease to the outside of the spacer.
3. Place the rod packing (26d**), packing spreader
(26c**), and housing (26f) on the packing rod (26h) .
4. Lightly tighten the packing nut (26e). The packing
nut is properly tightened when there is 3 lb (13.3 N)
of drag force when sliding the packing housing (26f)
assembly along the rod. Tighten or loosen the packing nut as needed.
5. Install the o-ring (26a**) on the outside of housing
(26f). Lubricate the o-ring with non-silicone grease,
Part No. 111265. Do not over-lubricate.
6. Install the spring (4) against the nut (E) as shown.
7. Install the packing rod assembly (26) into the gun

TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
