Operation 
16 3A3258D
+ Closing air valve decreases air flow 
through gun, which increases texture 
material flow through pump.
To achieve uniform spray pattern, adjust air
valve and flow adjustment nut on gun. If you
do not achieve the desired pattern, change
nozzles, see Recommended Nozzle
Selection Charts, page 15.
To Get Less Material
Try one or a combination of these methods:
• Open air valve.
• Turn gun flow adjustment nut 
counter-clockwise to decrease flow.
• Use smaller nozzle.
To Get More Material
Try any one or a combination of these
methods:
• Close air valve.
• Turn gun flow adjustment nut clockwise 
to increase flow.
• Use thinner material mixture.
• Use a larger nozzle.
For Continuous Spraying
Use trigger lock to hold trigger open and
reduce fatigue.
Check Material Consistency 
Periodically
Check and thin material as needed to
maintain proper consistency. The material
may thicken as it sits and slow down
production. Agitate periodically.
Preventing Material Surge at Gun 
Trigger (RTX1400si only)
Pressure will build up in the system when you
stop triggering the gun. To prevent material
surge at initial gun triggering:
• Point gun away from surface you are 
spraying when you first pull trigger. 
• When you first start to spray, hold the 
gun away from the surface and gradually 
work your way closer to it.
• Keep gun moving.
• After you begin spraying, trigger the gun 
as little as possible. 
Soft Start/Smart Start Operation 
RTX2000pi
Smart Start
Sprayer will start under the following
conditions:
• A new sprayer is plugged in and ON/OFF 
switch is turned ON.
• Gun is triggered and air valve is open far 
enough.
• There is a small leak in the system and 
the pressure drops below the pressure 
switch setting. This may appear to be 
random operation.
• When a bleeder gun is used.
• When there is no gun or hose connected 
to the sprayer.
• When the pressure is relieved by 
triggering the gun while the sprayer is 
OFF and then turned back ON.
• Prime valve is opened.
• There is a hose failure (leak) in the twin 
line hose.
Soft Start
•
The easiest way to tell if the Soft Start 
System is functional is to spray material. 
• The system is operating properly when a 
small amount of material initially comes 
out of the gun when triggered and the 
volume of material slowly increases to 
full spray.
NOTE: Motor runs when gun is triggered. 
Sprayer is designed to stop pumping when 
gun trigger is released.
