Operation
16 3A3258J
+ Opening air valve increases air flow
through gun, which decreases texture
material flow through pump.
+ 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 and RTX2500pi
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.
