7.If the shape of the spray pattern differs from the
image (Fig.6) refer to the troubleshooting section of
this document before proceeding.
If the shape, size and distribution of the spray droplets on
the second test are largely uneven, it would suggest the
atomization of the material is insufficient. Increase the air
flow slightly until the droplets seems more uniform
(Fig.7).
8.Now adjust the air diffuser horns so they are vertical.
9. If the paint appears very heavy it may mean the
viscosity or material is not right for the nozzle size.
Try reducing the flow control. If unsuccessful, select a
smaller nozzle.
If the coverage appears too little it suggests the nozzle is
too small. Step up a nozzle size and repeat the tests.
Begin spraying when you are happy with the results.
Experience through practice will speed up the
identification and adjustments necessary based on the
spray guns results.
SPRAYING TECHNIQUE (Fig.9):
Hold the spray gun at a right angle to the work piece
while maintaining an equal distance of approx. 20cm.
Move the gun across the work piece keeping it parallel all
the way. A fluid wrist action will be necessary.
Begin pulling the trigger before the leading edge of the
work piece is reached, holding it in fully as you travel
smoothly across and releasing after the trailing edge has
been passed.
Difficult areas such as corners should be sprayed first.
When spraying a corner maintain the angle of 90°.
Paint needs to equally cover both surfaces leading away
from the corner.
To hide the join and prevent streaking overlap by at least
50% across the previously painted surface.
6. MAINTENANCE
After each job and during prolonged breaks in spraying the gun must be cleaned thoroughly
inside and out to stop any material drying and clogging it up.
1. Empty the paint pot of any unused material into a suitable container for appropriate disposal.
2. Fill the pot with water and spray to flush the gun body through.
With the air supply disconnected:
1. Remove the lid and paint pot. Place in a cleaning bath briefly to soak.
2. Remove the air cap; immerse in water and scrub any remaining paint with the cleaning brush
supplied. Clear any clogged holes with the nozzle brush.
3. With the multi size spanner, remove the nozzle; immerse in water again clearing any clogged
