SPRAY GUN SETUP - AIR CONTROL (Fig.4):
The air control (F) regulates the volume of air passing
through the gun. As the air passes out through the
diffuser horns (E), it mixes with the paint being sprayed.
This causes the paint to breakdown in to tiny individual
droplets [atomization].
1.Twist the air control (F) anticlockwise to increase the
volume of air or clockwise to decrease the flow.
The 0 and Max. settings are stamped on either side of
the spray gun, adjacent to the air flow control.
SPRAY GUN SETUP - PAINT CONTROL (Fig. 5):
The paint control (G) adjusts the distance the trigger
(H) can be pulled.
1.Turn the paint control (G) clockwise to limit the
distance the trigger can be pulled (H).
2.Closing the control (G) clockwise will make the spray
pattern narrower.
CAUTION! Continuing to turn the paint control will
release the spring tension on the fluid needle allowing
removal.
SPRAY GUN SETUP - TEST PATTERN (Fig.6-8):
A
‘perfect’ spray gun setup is only ever a temporary
achievement; factors which affect this include the choice
of material, nozzle & air cap size and the compressor
conditions on the day.
Adjust the gun to a neutral starting setup and spray a test
pattern. Judge the pattern; continuing to spray further
tests and make fine adjustments until you are happy with
the results.
1.Set the air supply pressure and connect the spray
gun.
2.Open the spray pattern control fully anti clockwise to
give a wide pattern
3.Open the air control to Max.
4.Adjust the paint control anticlockwise so the trigger
has full movement.
5. Adjust the air diffuser horns so they are in the
horizontal position - giving an upright spray pattern.
6.On a piece of white paper [or other suitable media]
spray two test patterns: one holding the spray gun
still and approx. 20cm away from the paper. The
second keeping the gun parallel to paper while you
make a short pass sideways.
