12. Set the gun air regulator to deliver a minimum
of 45 psi (0.32 MPa, 3.2 bar) at the gun when
triggered, to ensure full spraying voltage. See
the table below.

13. Turn the atomizing air adjustment valve
counterclockwise until any tails disappear.
14. If desired atomization is not achieved, change
the tip size. The smaller the tip orifice, the finer
the atomization.
15. Spray a test piece. Examine the edges
for coverage. If wrap is poor, see
NOTE:
NOTE:
NOTE: If a narrower pattern is needed occasionally,
open the fan air adjustment valve slightly. (Excessive
fan air flow can cause paint buildup on the air cap.)
