Step 3: Spray Pattern Controls
Pattern Shape-Theshapeofthespraycanbeadjusted
from a round pattern to a flat pattern by turning the Pattern
Control Knob. Turning knob in rounds the pattern, turning
knob out flattens the pattern.
Pattern Orientation-Aflatorsemi-roundspraypattern
can be adjusted to any angle from horizontal to vertical by
turning the Air Nozzle. Pattern is perpendicular to “ears” on
nozzle. That is, when the ears are horizontal, the spray pat-
tern will be vertical and when the ears are vertical the spray
pattern will be horizontal.
Step 2: Air and Fluid Volume Controls
These two controls are used in conjunction with each other
toaccuratelyadjustair/uid(Paint)ratioandwillvaryfor
different paints. Changing one control Fluid Volume affects
the other so alternating back and forth between them to
netuneyouradjustmentwillyieldoptimumresults.
Air Volume Control-Airvolumeisadjustedbyturningthe
Air Fluid Volume Control Knob. Turning knob in reduces
volume, turning knob out Control Knob increases volume.
Fluid Volume Control- Fluid volume is adjusted by turning
the Fluid Volume Control Knob. Turning knob in decreases
volume, turning knob out increases volume. Once a
satisfactory volume is set, you can lock the adjustment by
turning the lock nut in tight.
OPERATION
Step 1: Inlet Air Pressure Regulation
Assemble components of spray gun and connect to clean
air source as described above. Clean air source is impera-
tivetoensurepeakperformance.Theuseofanin-lineair
lterishighlyrecommendedtokeepanycontaminants
from entering the spray gun. Set inlet air pressure to
between 40 and 45 P.S.I. to begin adjustments.
(This is a good operating inlet pressure suitable for most applica-
tions, however, depending on materials being sprayed and other
external factors such as temperature, humidity, etc., you may
need to come back to this step and increase or decrease pres-
sure as needed after attempting adjustments in step 2.)
Inlet pressure is adjusted by turning the Pressure Regula-
torControlKnob.Knobmustrstbepulledouttounlock.
Turning knob clockwise increases pressure, turning knob
counter-clockwisedecreasespressure.Oncedesired
pressure is reached, push the knob back in to lock the
adjustment.
CARE & MAINTENANCE
Warning! Clean gun before and after each use.
Toprotecttheprecisionmachinedinternalpartsandttings
in this gun from corrosion during shipping, some oils or
other corrosion resistant agents may have been applied.
It is important to remove any such residue before attempt-
ing to use the gun. To clean, place a small amount of
appropriate thinner into paint cup and spray through gun
while pulling and releasing trigger repeatedly. Wipe exterior
of gun, nozzles and paint cup. In some cases, if the gun
becomes clogged, disassemble completely and soak all
parts in thinner. After soaking, use wire and cleaning brush
to clear small internal passages. Check and clean paint cup
lter.Replaceifworn.
A clean air source is imperative to ensure peak perfor-
mance.Theuseofanin-lineairlterishighlyrecommend-
ed to keep any contaminants from entering the spray gun.
Inspectallttingsandhardwaretoensureproperseating.
Besureairlinettingsaretightwithnoleaks.Replaceany
worn parts as necessary.
Check needle and nozzles for nicks, scratches or burrs.
Any such conditions will seriously impair performance.
Replace as necessary.
