Read all safety warnings before operation.
WARNING!
All persons in the work area must always wear approved eye and ear protection and
approved breathing apparatus when this spray gun is in operation.
Never aim spray gun at anyone. Do not spray near sparks, open flame, lit cigarettes, pilot
lights, space heaters or any other potential ignition source. DO NOT SMOKE IN WORK
AREA.
Follow manufacturers instructions and safety information to ensure safe handling and
proper use of paints, lacquers, thinners, base coats, etc. Do not use latex or other heavy
paints. They are not recommended for this spray gun.
Warning! Solvents 1,1,1-Trichloroethane and Methylene Chloride (Dichlormethane - some-
times called Methylchloride) can chemically react with the Aluminum used in most spray
equipment creating an explosion hazard. Read the label or data sheet from the mate-
rial you intend to spray. NEVER USE ANY MATERIAL CONTAINING THESE SOLVENTS. If
unsure as to the composition of your material, check with your supplier. Do not use acids
for cleaning.
Always keep work area free from obstructions and well ventilated.
Always disconnect spray gun from air source before disassembly.

HVLP NOTICE
This High Volume Low Pressure
(HVLP) compliant spray gun was
designed to provide maximum transfer
efficiency by limiting air cap pressure
to 10 PSI when used properly.
To maintain a maximum air cap
pressure of 10 PSI at the nozzle,
use a maximum of 36 PSI at the inlet.
*

Clean gun before and after each use. To protect the precision machined internal parts and fittings
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 attempting 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 filter. Replace if worn.
A clean air source is imperative to ensure peak performance. The use of an in-line air filter is
highly recommended to keep any contaminants from entering the spray gun.
Inspect all fittings and hardware to ensure proper seating. Be sure air line fittings 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.
OPERATION
4
STEP 1.
Inlet Air Pressure Regulation
Assemble components of spray gun and connect to clean air source as described above.
Set inlet air pressure to between 20 and 30 P.S.I. to begin adjustments.
(This is a good operating inlet pressure suitable for most applications, 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 pressure as needed after attempting adjustments in step 2.)
Inlet pressure is adjusted by turning the Pressure Regulator Control Knob. Knob must first 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.

Air and Fluid Volume Controls - These two controls are used
in conjunction with each other to accurately adjust air/fluid (Paint)
ratio and will vary for different paints. Changing one control
affects the other so alternating back and forth between them to
fine tune your adjustment will yield optimum results.
Air Volume Control - Air volume is adjusted by turning the Air
Control Knob. Turning knob in reduces volume, turning knob out
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.
Spray Pattern Control
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 pattern will be vertical
and when the ears are vertical the spray pattern will be
horizontal.

years of trouble free use when cared for as described in the "Maintenance and inspection" section
on page 4. However, as with any mechanical device, periodic adjustments are necessary to
maintain a peak level of performance. Should your spray gun be displaying any of the following
symptoms, the simple procedures shown below will correct the problem.
Half-Moon Shaped Pattern
This is usually caused by
clogged air holes on the Air
Nozzle ears.

This can be caused by
1. A dirty or damaged Needle
tip or Fluid Nozzle
2. Clogged atomization holes
on Air Nozzle around the
center
Spitting
1. Too little material in cup
2. Loose Fluid Nozzle
3. Damaged Needle Packing
4. Dirty or damaged Needle &
Nozzle Set.
Material in cup bubbles or
“Boils”
1. Loose, clogged or damaged
