For the recommended hook-up, see fig. 1.
5.1. Ensure that the air valve is in the "off" position before connecting to the air supply.
WARNING! Ensure that the air supply does not exceed 50psi. Too high an air pressure and/or unclean air will shorten the
product life due to excessive wear and may be dangerous causing possible damage and/or personal injury.
5.2. Drain the compressor tank daily. Water in the air line will damage equipment and will invalidate your warranty.
5.3. Clean the compressor air inlet filter screen weekly.
5.4. Line pressure should be increased to compensate for
unusually long air hoses (over 8 metres). The minimum
hose and fittings bore is 10mm I.D.
5.5. Keep hoses away from heat, oil and sharp edges.
Check hoses for wear, and make certain that all connections
are secure.
5.6. Spray gun input connection is 1/4”BSP.
5. AIR SUPPLY
6.1. For best results, handle the gun correctly. It should be held perpendicular to the
surface being sprayed and moved parallel to it. Start the stroke before squeezing
the trigger and release the trigger before finishing the stroke. This will enable you
to accurately control the gun paint (fig. 2).
6.2. Spray from a distance of about 6 to 10 inches depending on the material and the
atomizing pressure. The material deposited should always be even and wet.
Each stroke must overlap the preceding stroke to obtain a uniform finish.
To reduce overspray and obtain maximum efficiency, spray with the lowest possible
atomizing air pressure.
6.3. Controlling the fan spray and the fluid;
6.3.1. If a fluid pressure tank is used, the amount of fluid can be controlled by regulating the
pressure on the tank. Otherwise, use the fluid control screw on the gun (fig. 3.A). Turn right to decrease
the flow, left to increase.
6.3.2. As the width of the spray is increased (with knob fig. 3.B), more material must be allowed to pass
through the gun to obtain the same coverage on the increased area.
6.3.3. The direction of the fan spray, either horizontal or vertical, is obtained by turning the air nozzle
to the desired position then tightening the retaining ring. The spray pattern of the gun is variable from
round to flat with all patterns in between. In normal operation, the wings on the nozzle are
horizontal. This provides a vertical fan-shaped pattern which gives maximum uniform and even coverage
when moving the gun back and forth, parallel to the work surface, see fig. 4.
6.4. Syphon spraying
Set the atomization pressure at approximately 45psi for lacquer and 50psi for enamel then test spray.
If the spray is too fine, reduce the air pressure or open the fluid control screw. If the spray is too coarse,
close the fluid control screw. Adjust the pattern width and repeat the adjustment of the spray if necessary.
6.5. Pressure spraying
Set the fluid pressure for the desired flow. Open the atomization
air and test spray. If the spray is too fine, reduce the air pressure. If it is too coarse, raise the air pressure.
Adjust the pattern width and repeat the adjustment of the spray. Keeping the fluid control screw in the
open position will reduce fluid needle wear.
Note: To reduce overspray and obtain maximum efficiency, always spray with the lowest possible atomization air pressure.
6. OPERATION
fig. 1
fig. 2
When reassembling after maintenance or cleaning, take care when screwing parts together. First screw parts hand tight to avoid cross-
threading. If a part cannot easily be turned by hand, check that you have the correct part, or unscrew, realign and try again.
DO NOT use excessive force when reassembling.
7.1. Spray gun
1. Immerse the front end of the gun only in solvent until the solvent just covers the fluid connection. Do not immerse the entire gun in
solvent. This will cause lubricants to dissolve and other packings to dry out. Dirty solvent may also clog the small narrow passages
in the gun.
2. Use a bristle brush and solvent to wash off accumulated paint and wipe the outside of the gun with a dampened solvent rag.
3. Lubricate the gun daily with a light machine oil. Be sure to lubricate the fluid needle packing, air valve packing, side port control
packing and trigger pivot point. Do not use lubricants containing silicone.
4. When finished spraying, flush the gun through with clean thinners.
7.2. Air nozzle, fluid nozzle and needle assembly
1. To clean the nozzles, soak them in solvent to dissolve any dried material then blow them clean with air. Handle all nozzles carefully
and do not make any alterations in the gun.
2. If you need to probe the holes in the nozzles, be sure to use a tool that is softer than brass; do not use metal instruments.
3. Adjust the fluid needle valve so that when the gun is triggered, air flow occurs before fluid flow.
7. MAINTENANCE & CLEANING
fig. 4
fig. 3
Original Language Version SG6T Issue: 2 - 02/03/10

A faulty spray is usually caused by improper cleaning or dried material around the fluid nozzle tip or in the air nozzle. Soak these parts in a
solvent that will soften the dried material and remove with a brush or a cloth. Never use metal instruments to clean the air or fluid nozzles.
These parts are carefully machined and any damage to them will cause a faulty spray. If either the air nozzle or fluid nozzle is damaged, the
part must be replaced before a perfect spay can be obtained.
8. TROUBLESHOOTING
Dried material in a side port restricting passage of air. Greater
flow of air from the cleaner side port forces fan pattern in the
direction of the clogged side.
Dried material around the outside of the fluid nozzle tip
restricts the passage of atomizing air at one point through the
centre opening of the air nozzle and results in the pattern
shown.
This pattern can also be caused by a loose air nozzle.
A split spray or one that is heavy on each end of a fan pattern
and weak in the middle is usually caused by too high
an atomization air pressure or by attempting to get too wide a
spray with thin material.
1. Dried out packing around the material needle valve permits
air to get into the fluid passageway. This results in spitting.
2. Dirt between the fluid nozzle seat and body or a loosely
installed fluid nozzle will cause the gun to spit.
3. A loose or defective swivel nut on the syphon
cup or material hose can cause spitting.
Dissolve material in the side ports with thinner, then blow the gun
clean. Do not use metal instruments to clear parts.
Remove the air nozzle and wipe off fluid tip using a rag dampened
with thinner. Tighten the air nozzle.
Adjust air pressure/fan width.
1. Unscrew the knurled nut slightly and place two drops of machine
oil on the packing then replace the nut and finger tighten.
In extreme cases, replace the packing.
2. Remove the fluid nozzle, clean the back of the nozzle and the
nozzle seat in the gun body using a rag dampened with thinner.
Replace the nozzle and secure it tightly against the body.
3. Tighten or replace the swivel nut.
