Component Description

Flow and Air Control

Fig. 1. The flow control (A) has a shut off and pressure

relief feature to soft start each time the gun is trig-

gered, instead of a blast of unatomized material. The

flow control has three modes:

LOW/MED/HIGH: Triggering the gun sends an air

signal to the flow control that closes the prime valve

and starts the pump which fills the material hose.

When the gun trigger is released, the prime valve

opens and relieves the system pressure into the

supply container. When the gun is triggered the

automatic pressure relief, special TexSpray hoses

and pump design eliminate blasts of material and

spray pulsing to ensure consistent atomization.

OFF: 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.

PRIME: The prime valve remains open so material

circulates through the pump and back to the supply

container through the drain hose.

The air control (B) increases or decreases the air

pressure to the sprayer from the air supply.

TexSpray Gun, 235490

EQUIPMENT MISUSE HAZARD

The TexSpray Gun 235490 is for use

only with the GM 1030 TexSpray 234113

which is designed so the fluid pressure

of the gun will not exceed the working pressure

rating of the components. The maximum fluid work-

ing pressure of the GM 1030 TexSpray is 750 psi

(5.1 MPa, 51 bar), but the recommended maximum

is 500 psi (3.4 MPa, 34 bar).

WARNING

INSTRUCTIONS

Fig. 2. Air flow is controlled at the gun. During priming,

turn the gun air control valve (D) 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 opera-

tion, open the air control valve to introduce air at the

correct volume for the desired spray pattern. The gun

also has a trigger bail (E) to reduce operator fatigue

when spraying large surfaces.

TexSpray Hoses

CAUTION

Use Graco hoses designed for this sprayer. Using

other hoses will damage the flow control.
