DESCRIPTION:
The AUT- Series Manual Spray Gun can be used with light to
medium consistency materials for touch-up, shading and finishing
of small parts. It can cover a range of materials to include light
lacquers, latex or corrosives.
AIR AND FLUID CONNECTIONS:
Air Inlet 1/4” N.P.T. and Fluid Inlet 1/4” N.P.T.
OPERATION:
1. Before using, blow out air hoses with compressed air to
remove foreign particles.
2. Connect airhose to U-49A Valve Casing for type AUT-
(Thumb-Action) Spray Gun .
3. Keep connections tight, any leakage of air will impair operation
of Spray Gun and waste air pressure.
4. Siphon Cup: Attach Cup to the fluid body assembly when 1/4”
N.P.T. threaded inlet is in the down position.
5. Gravity Cup: Loosen U-58 Nut and turn fluid body inlet to the
top of Spray Gun; tighten U-58. A gravity feed cup will feed fluid
approximately 30% faster than a siphon feed cup. This permits
detail work with head of spray gun close to the work surface
(cup on top) .
6. Air and Fluid Connections for Pressure feed setup:
Attach Airhose to 1/4” N.P.T.
1. Air Connection: To remove any accumulated foreign matter blow
out all hoses before using.
a. Air supply to Spray Gun must be turned off before attaching
fitting to the Air Inlet.
b. Attach Air Hose to the Air Outlet on the Air Regulator and Air Inlet
on the bottom of the handle on the Spray Gun.
Attach Fluid Hose to 3/8” N.P.S.( Make sure all fittings are tight).
2. Fluid Hose: Run Fluid Hose from Spray Gun to Pressure Pot.
a. Attach Hose to the fluid inlet of the Fluid Body.
7. To control Fluid: Depress lever to increase flow.
8. A fan is used for broad patterns. Stipple effects can be obtained
by reducing atomizing pressure until dots are produced.
9. A round pattern is used for narrow work, stippling,stenciling
and shading.
10. As width of pattern increases flow of material must be increased
proportionately to obtain fast coverage of larger areas.
By proper adjustment, patterns up to 6” may be obtained with
size 3 Spray Head Components.
11. Hold Spray Gun using a hand shake position with thumb on
lever. Can also be held like an airbrush with Index finger laying
on trigger lever.

WARNING: Spray materials may be harmful if inhaled or
allowed to come into contact with the skin or eyes. Consult
the product label and Material Safety Data Sheet supplied
for the spray material. Follow all safety precautions.
CAUTION: Well Ventilated Area Required to remove
fumes, dust or overspray. Secure airhose and fluid
hose wrench tight for safety and to prevent leaks.

12. Begin painting with as light a coat as possible. Take long
strokes from side to side, releasing trigger at the end of each
stroke. Check to make sure each stroke meets without much
overlapping which can cause material to run. For general
painting hold the Spray Gun with head approximately 2” to
6” from the surface. For narrow lines, approximately 1” to
2”, use a Round Aircap and short trigger pull and hold Spray
Gun close to surface.To obtain a wider spray, pull trigger
back while gradually drawing the head of the gun away from
surface until desired width of pattern is reached.
TROUBLE SHOOTING SPRAY PATTERNS:
A. A ROUGH OR STIPPLE FINISH is due to low or restricted flow of
air pressure or heavy materials being applied with the spray gun too
close to surface.
B. A WET OR SAGGING FINISH is due to low air pressure or restricted
flow of air, material being too thin or applied too close to the surface.
C. A SPUTTERING SPRAY is caused by air leaking into fluid line
or can be caused by a loose fluid tip, a broken or split tip, lumpy
material, a clogged vent hole in cover of material cup, air leak at fluid
pipe attached to inside of tank cover, or a clogged paint strainer.
TO CORRECT: Tighten tip securely or replace. Strain material and
clean strainer. Sputtering might also be caused by worn packing
washers, or worn or scored needle.
D. AN ARCHED FAN SPRAY PATTERN is caused by dried material
accumulated in one fan port of the multiplehead, distorting the
pattern.
TO CORRECT: Dissolve material inside fan port with suitable
water/solvent applied with a small brush.
Never use wire or sharp instruments to clean fan ports as
permanent damage to the air ports will result in altering
uniformity of the fan spray pattern.
E. UNBALANCED FAN SPRAY PATTERN, heavy on one side, may
be caused by material collecting around outside of the fluid tip and
aircap, or by a loose aircap.
TO CORRECT: Remove aircap and clean fluid tip and aircap with
water/solvent, dry with air pressure. Always be sure fan aircap and
aircap body is tightened securely.
F. A HEAVY CENTER in a fan pattern is caused by insufficient air
pressure at the fan port. Rough or shady edges are also caused by
low air pressure.
TO CORRECT: Increase air line pressure.
G. A SPLIT FAN SPRAY PATTERN, heavy on each end and light in
the center, is caused by excessive air pressure.
TO CORRECT: Reduce air pressure.
