CHOOSING FLUID SETS
The fluid set includes a Needle, a Nozzle and an
Air Cap. These parts are a matched set. Do not mix
parts from other sizes. The standard fluid set which
comes with the gun is a 1.3mm, which will work
well for most applications.
Different sizes of fluid set will give different flow
rates. A more viscous fluid will need a larger size. A
thinner fluid will need a smaller size.
TO CHANGE TO A DIFFERENT FLUID
SET
1. Loosen and remove the Air Cap.
2. Unscrew and remove the Nozzle. Whenever
tightening or loosening the nozzle, pull the
trigger all the way and hold it to prevent
damage to the seating surfaces of the Needle
and Nozzle.
3. Unscrew the Fluid Control Knob all the way
and remove it, together with the spring.
4. Pull out the Needle through the back of the
Gun.
5.
Replacement is the opposite of removal.
ADJUSTING THE GUN
The gun will normally need to be adjusted before
each use. This is similar to tuning a musical
instrument before playing it.
1. First adjust the Fluid Flow Control Knob. Turn
anti-clockwise for more fluid, clockwise for
less fluid. A good starting point would be
about 2-1/2 turns out from closed.
2. Test the spray pattern and atomization on a
test piece. Hold about 20cm (8 inches) away.
Turn the Pattern Adjustor knob for the desired
pattern.
3. Adjust the Speed Control knob on the turbine
to control the air volume. Generally, it is best
to use the minimum air volume which will
achieve satisfactory atomization. The point
is to get the droplet size as small as possible
while still having the desired coverage.Too
much air will only cause overspray mist and
waste paint. If the Speed Control knob is at
maximum and the atomization is still not
satisfactory, the atomization can also be
controlled by thinning the paint. One can also
use a different fluid set ( the needle, nozzle
and air cap).
