atomizationiscorrect.
Always turn the pressure control knob to the lowest setting

5. Spraying technique
Injection hazard. Do not spray without the tip guard
in place. NEVER trigger the gun unless the tip is
completely turned to either the spray or the unclog
position. ALWAYS engage the gun trigger lock
before removing, replacing or cleaning tip.
The key to a good paint job is an even coating over the entire surface.
Keepyourarmmovingataconstantspeedandkeepthespraygunat
a constant distance from the surface. The best spraying distance is 25
to 30 cm between the spray tip and the surface.
25 - 30 cm
Keepthespraygunatrightanglestothesurface.Thismeansmoving
your entire arm back and forth rather than just exing your wrist.
Keepthespraygunperpendiculartothesurface,otherwiseoneend
of the pattern will be thicker than the other.
Trigger gun after starting the stroke. Release the trigger before
ending the stroke. The spray gun should be moving when the trigger
is pulled and released. Overlap each stroke by about 30%. This will
ensure an even coating.

If very sharp edges result or if there are streaks in the
spray jet – increase the operating pressure or dilute
the coating material.
