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:
D LOW/MED/HIGH: T riggering 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 th e gun is triggered the
automatic pressure relief, special TexSpray hoses
and pump design eliminate blasts of material and
spray pulsing to ensure consistent atomization.
D 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.
D PRIME: The prime valve remains open so material
circulates through the pump and back to the supply
container through the dra in hose.
The air control (B) increases or decreases the air
pressu re 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
rati ng of the components. The maximum fluid work-
ing pressu re 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 yo u to check
and adjust the fluid flow accurately. (When this va lve is
closed the air exits the rear of the gun.) During opera-
tion, open th e air control valve to introduce air at the
corre ct volume for the desired spra y pattern. The gun
also has a trigger bail (E) to reduce operator fatigue
when spraying large surfaces.

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