• Hold the gun perpendicular to the surface, 6" to 8"
distance.
• Follow contour.
• Overlap each stroke 50%.
• Ends are feathered by triggering. That is, begin
stroke before pulling trigger and releasing just before
ending the stroke.
• Spray edges and corners first. This will reduce over-
spray while providing good coverage on corners.
• Don't arc strokes, move the gun parallel to work.
Your pattern should normally be shaped like this.
If not, see Troubleshooting guide.
Thoroughly clean the spray gun after each use.
1. Turn off air supply, and remove cup from lid.
2. Empty the material from cup and rinse with a clean
solvent (thinner).
3. Fill cup with solvent and attach to the lid.
7. Wipe the outside of the spray gun and cup with a
solvent soaked cloth. DO NOT IMMERSE THE
GUN IN SOLVENT -- THIS WILL WASH OUT
THE LUBRICANTS AND DRY OUT
PACKINGS.
8. To clean the air cap and fluid tip, remove them , soak
in suitable solvent and wipe clean with a clean cloth.
If the holes are plugged, use a wooden toothpick to
remove any material particles. NEVER use a needle
or any other metal object as this may damage the
holes and result in imperfect spray patterns. When
reassembling the fluid tip, take care not to overtighten
(160-200 in.lbs. torque is recommended) or cross
thread the fluid tip into the gun body.
4. Turn on the air supply and spray solvent through the
spray gun. While spraying, shake the gun up and
down to remove all excess material from the lid.
Repeat Steps 1-4 above with a clean solvent until all
traces of material are removed.
5. Turn off air supply to gun.
6. To clean the vent orifice and interior of shroud the lid
assembly must be disassembled and wiped with
solvent. This is easily accomplished by unscrewing
the shroud retaining sleeve. When reassembling,
orient the fluid pick-up tube bend away from the
handle, then tighten the shroud retaining sleeve hand
tight.
NOTE
Always clean with reduced air pressure. An
air pressure no greater than 15 to 20 PSI will
allow quick and thorough cleaning of the cup
and gun.
After cleaning the spray gun, apply a few drops of light
household oil to the fluid needle next to the packing
retainer, on the threads of the air valve assembly and
that part of the valve stem which protrudes from the gun
body. All springs should be given a coating of light
grease periodically.
NOTE
If water is used as a solvent to clean the gun,
spray paint thinner or mineral spirits through
the gun after cleaning to remove any excess
moisture and protect parts.
