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

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
Troubleshooting, page
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.)
