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:
DLOW/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.
DOFF: 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.
DPRIME: 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
WARNING
| EQUIPMENT MISUSE HAZARD | |
| The TexSpray Gun 235490 is for use | |
INSTRUCTIONS | 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).
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.

Use Graco hoses designed for this sprayer. Using other hoses will damage the flow control.
