Easy Spray Control
The Easy Spray Control (A) has a quick shut off and
pressure relief feature so you get a soft start each time
you trigger the gun, instead of a blast of unatomized
material. See Fig. 1. The control has three modes:
D SPRAY/FILL HOSE: Triggering the gun sends an
air signal to the Easy Spray Control that closes the
Automatic Pressure Drain Valve and starts the
pump which fills the material hose. When the gun
trigger is released, the Automatic Pressure Drain
Valve opens and relieves the system pressure into
the supply container. This automatic pressure relief
and the special TexSpray hoses and pump design
eliminates blasts of material when the gun is trig-
gered and eliminates "spray pulsing" to ensure
consistent atomization.
D OFF/RELIEVE PRESSURE: Puts the sprayer in
neutral/relieve pressure – neither the pump nor the
gun will operate and there is no material pressure in
the pump, hose or gun.
D PRIME PUMP: The Automatic Pressure Drain Valve
remains open so material circulates through the pump
and back to the drum through the drain hose.

Automatic Pressure Drain Valve
The pressure drain valve (B) automatically relieves
system pressure when you release the gun trigger and
the valve also stops the pump. See Fig. 1.
TexSpray Gun, 235490
WARNING
EQUIPMENT MISUSE HAZARD
The TexSpray Gun 235490 is for use
only with the GM 1030 TexSpray 231300
INSTRUCTIONS
which is specially designed so that the
fluid pressure of the gun will not exceed the
working pressure rating of the components. The
maximum fluid working pressure of the GM 1030
TexSpray is 1000 psi (7 MPa, 70 bar), but the rec-
ommended maximum is 150 psi (1 MPa, 10 bar).

The operator controls the air flow at the gun. During
priming, turn the gun's Air Control Valve (C) in fully to
prevent air from mixing with the fluid, which allows you
to check and adjust the fluid flow accurately. (When
this valve is closed the air exits the rear of the gun.)
During operation, open the Air Control Valve to
introduce air at the correct volume for the desired
spray pattern. The gun also has a trigger bail (D) to
reduce operator fatigue when spraying large surfaces.
See Fig. 2.

Optional Flow Restrictor, 190109
This accessory (E) restricts the flow of fluid to the gun
when using thin materials. Install as shown in Fig. 3.

TexSpray Hoses
CAUTION
Use only the genuine Graco hoses designed for
use with this sprayer. Using other hoses will
damage the Easy Spray Control.
Optional 2 gpm Pump Kit, 235965
This accessory kit (not shown) directly replaces the
standard TexSpray three gpm pump. Use it when
spraying smooth and fine textures where lower volume
is important for better control. The accessory operates
in the 1/4 to 2 gpm range.
