Operation (Pressurized Hopper Gun)

Adjusting the System
(Pressurized Gun Only)
Sufficient fluid output (volume and pressure)
and good atomization is a balance of
atomizing air, material thickness/material
flow and nozzle selection. Achieving the
correct balance for your application requires
experimentation to achieve desired results.
Keep in mind these important points when
adjusting gun:
To select correct nozzle for your
applications, consider size of aggregate
in material and coarseness of spray
pattern. Remember the larger the
material nozzle, the larger the pattern.
Set material flow by closing air flow
valve, and adjusting material flow
regulator, while pulling trigger to get the
appropriate material flow.
Start spray system with air flow valve
completely open. If needed, slowly
close gun air flow valve until you get the
desired spray pattern. Use minimum
amount of air at spray gun to achieve
proper spray pattern and to minimize
bounce back.
+ Test spray pattern on cardboard.
Hold gun 18 to 48 in. (45.7 to 122 cm)
from surface. Use this spraying dis-
tance for most applications.
+ When spraying with a material nozzle
only, overlap each stroke 50% in a cir-
cular motion.
+ When spraying with a material nozzle
and disc, overlap each stroke 50% in a
linear motion.
Gun air flow is regulated using air flow
valve located on the left side of the gun.
+ Opening air flow valve (counterclock-
wise) increases air flow through gun.
+ Closing air flow valve (clockwise)
decreases air flow through gun.
For Less Material Flow
Try one or a combination of these methods:
Turn material flow regulator knob
counter- clockwise on gun to decrease
material flow.
Use thicker material mixture.
Use smaller material nozzle.
Decrease needle travel.
For More Material Flow
Try any one or a combination of these
methods:
Turn material flow regulator knob
clockwise on gun to increase material
flow.
Use thinner material mixture.
Use a larger material nozzle.
Increase needle travel.
For Continuous Spraying
Use trigger lock to hold trigger open and
reduce fatigue (only on gravity-fed gun)
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.
