GENERAL INFORMATION
CONVERTING
TO REMOTE PRESSURE
FEED
I,. Remove suction cup and lid assembly by loosening and
removing the swivel nut (36),
2 The spray gun is now ready to be connected
to any
pressure feed tank with a standard 3/8" straight pipe
female connection°
OPERATION
1. Shut off fluid flow through gun by turning fluid needle
adjusting screw (25) clockwise as far as it will goo Do not
force.
6 If the gun sprays too fast (runs or sags), lower the air and
fluid pressure.. If too slow, increase pressure. Adjust to
balance pressure.
2, Keep the air pressure as low as possible.
3r Open (turn counterclockwise) air valve assembly (10)
until the first thread is flush with the back of guno This is
the full open position,
4. Hold the trigger (13) back and gradually open the fluid
needle adjusting screw (25) until a desired pattern is
obtained.
5. Trigger the gun quickly, one second on-offo Spray a small
test pattern°
When using internal mix air cap, begin with the same air and
fluid pressure°
The SG5-0010
air valve (10) is under pressure
whenever
the gun is triggered.
If the valve is
turned out too far, it mayleave
the gun forcefully
when the gun is triggered. The "0" ring may also
be damaged.
Do not turn the valve out past the
first thread--there
will be no effect on the spray
pattern after that position.
MAINTENANCE
Thoroughly clean the spray gun after each use°
1o 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_
NOTE
Always clean with reduced air pressure. An
air pressure no greaterthan
15 to 20 PSI will
allow quick and thorough
cleaning of the
cup and gun.
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 I-
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 hole, shut offair to gun, hold the trigger
back and turn gun assembly upside down over solvent
container. Allow solvent to drip out vent hole in lid until
clear solvent is seen..
7,
.
Wipe the outside of the spray gun and cup with a solvent
soaked cloth. DO NOT IMMERSE THE GUN IN SOL-
VENT - THIS WILL WASH OUT THE LUBRICANTS
AND DRY OUT PACKINGS.
To clean the air cap and fluid tip, remove them (see Air
Caps), 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 reas-
sembling the fluid tip, take care not to overtighten (160-
200 in.lbso torque is recommended) or cross thread the
fluid tip into the gun body.
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.
After cleaning the spray gun, apply a few drops of light
household oil to the fluid needle (21) next to the packing
retainer (9), on the threads of the air valve assembly (I0) and
that part of the valve stem (.20) which protrudes from the gun
body, All springs should be given a coating of light grease
periodically
