SS-1150 AIR SPRAY GUN
Your new spray gun is exceptionally rugged in construction. And is built to stand up under hard. Continuous
use. However, like any other fine precision instrument. Its most efficient operation depends on a knowledge
of its construction. Operation and maintenance. Properly handled and cared for it will produce beautiful.
Uniform finishing results long after other spray guns have worn out.

Gun Handing
The first requirement for a geed resultant finish is the proper handing of the gun. The gun should be held
perpendicular to the surface being covered, and moved parallel with it. The strike should be started before
the trigger is pulled and the trigger should be released before the strike is ended. This gives accurate control
of the gun and material.
The distance between gun and surface should be 6 to 12 inches depending on material and atomizing
pressure. The material deposited should always be even and wet. Lap each stroke over the preceding stork
to obtain a uniform finish.
Note: to reduce overspray and obtain maximum efficiency. Always spray with the lowest possible atomizing
air pressure
Spray width adjustment, turn right for round, left for fan
Fluid control screw, turn to right to decrease flow, left to increase.
As width of spray is increased, more material must be allowed to pass through
the gun to obtain the same material must be allowed to pass through to gun to
obtain the same coverage on the increased area.
Siphon spraying
Set atomization pressure at approximately 50psi for lacquer and
60 psi for enamel. Test spray. If the spray is too fine. Reduce
the air pressure or open fluid control screw. If the spray is too
coarse, close the fluid control screw. Adjust the pattern width
and repeat adjustment of spray necessary.

2
Pressure Spraying
After selecting correct size fluid orifice, set fluid pressure for desired flow.
Open atomization air and test spray.
If spray is too fine reduce air pressure.
If Spray is too coarse, raise air pressure. Adjust pattern width and repeat adjustment
of spray.
Keep fluid control screw in open position will reduce fluid needle wear.
Note: To reduce overspray and obtain maximum efficiency. Always spray with the
lowest possible atomization air pressure
Faulty Patterns And How To Correct Then
Pattern
Cause
Correction
Dried material in side-port “A”
restricts passage of air. Greater
flow of air from cleaner side-port
“B” forces fan pattern in, direction
of clogged side.
Dissolve material in side-port with thinner,
then blow gun clean. Do not poke into
openings with metal mstruments.
Dried material around the
outside of the fluid nozzle tip at
position “C” restricts the
passage of at atomizing air at
one point through the center
opening of air nozzle and results in pattern
shown.
This pattern can also be caused by loose air
nozzle.
Remove air nozzle and wipe off fluid tip.
Using rag wet with thinner tightcn air nozzle.
A spit spray or one that is heavy on each end
of a fan pattern and weak in the middle is
usually caused by (1) too high an atomization
air pressure, or (2) by attempting to get too
wide a spray with thin material.
Reducing air pressure will correct cause (1).
To correct cause (2), open material control to
full position by turning to left. At the same
time, turn spray width adjustment to right.
This will reduce with of spray but will correct
split spray patter.
(1) Dired out packing around material
needle valve permits air to get into fluid
passageway. This results in spitting
(2) Dirt between fluid nozzle seat and body
or loosely installed fluid nozzle will
make gun spit
(3) A loose or defective swivel nut on
siphon cup or material hose can cause
spitting.
Too correct cause (1)
back up knurled nut (E).
please two drips of
machine oil in packing.
Replace nut and tighten
with fingers only. In aggravated cases,
replace packing.
To correct cause (2). Remove fluid nozzle
(F). clean back of nozzle and nozzle seat in
gun body using rag wet with thinner. Replace
nozzle and draw up tightly against body.
To correct cause (3). Tighten or replace
swivel nut.
General Maintenance
Spray gun
1. Immerse only the front end of the gun until solvent just covers fluid connection.
2. Use b bristle brush and solvent to wash off accumulated paint
3. Do not submerge the entire spray gun in solvent because.
a. The lubricant in the leather packings will dissolve and the packings will dry out.
b. The lubricant at wear surfaces will dissolve causing
c. Residue from dirty solvent may clog the narrow air passages in gun.
4. Wipe down the outside of the gun with solvent dampened rag.
5. Lubricate gun daily. Use a light machine oil on:
a. Fluid needle packing
b. Air valve packing.
c. Side port control packing
d. Trigger pivot point.
6. Caution: never sue lubricants containing silicone. This material may cause finish defects.
Precautionary not
All parts on a spry gun should be screwed in hand tight at first, this will avoid the possibility of cross
threading the parts. If the parts can not be turned by hand easily, make sure you have the correct parts,
unscrew, realign, and try again. Never use undue force in mating parts.
Air nozzle, fluid nozzle, needle assembly
1. All nozzles and needles are precision made. They should be handled with care.
2. Except as described in 5, do not make any alterations in the gun. To do so could cause finishing
difficulties.
3. To clean nozzles, soak them in solvent to dissolve any dried material, then blow them clean with air.
4. Do not probe any of the holes in the nozzles with metal in truments. If probing is necessary, use only a
tool that is softer than brass.
5. Adjust the fluid needle valve so that when gun is triggered, air flow occurs before fluid-flow.
Pointers On Cleaning
When used with siphon cup
A compatible thinner or solvent should be siphoned through gun by
inserting tube in open container of that liquid. Trigger gun
repeatedly to flush passageway thoroughly and to clean tip of
needle.
When used with pressure tank
Shout off air supply to tank and release pressure on tank.
Open vent and loosen air nozzle, hold a piece of cloth over the air
nozzle and squeeze trigger.
Air will back up through fluid nozzle, and force fluid out of hose into
tank.

3
Next, put enough thinner into tank to wash hose and gun thoroughly.
Spray thinner though the gun until it is clean.
Attach fluid hose to air line and blow it out thoroughly to remove all traces of materials and to dry it.
Air supply
The oil and water extractor should not be mounted on or near the air compressor.
The temperature of air is greatly increased during compression.
As the air cools down to room temperature, in the air line, on its way to the spray tun, the moisture contained
in it condenses.
Thus, for maximum effectiveness, the oil and water extractor should be mounted at some point in the air
supply system where the temperature of the compressed air in the line is likely to be lowest.
Air lines must be properly drained
Pitch all air lines back towards the compressor so that condensed moisture will flow back into air receive
where it can be drained off.
Each low point in an air line acts as a water trap. Such point should be fitted with an easily accessible drain.
See diagram above.
