4. Flush the gun into an appropriate container after every test shot.


Note: It may be that 20psi will be adequate pressure to establish a fan pattern.

5. If the first test shot had an established fan pattern, back off 5psi and shoot

another pattern. Keep backing the pressure off until the unit no longer produces
a fan. Then increase the operating pressure until there is just enough to form a
soft-looking spray fan.

6. If the pressure was not adequate to form a well-defined fan pattern, increase the

main pressure by 5psi and do another short test spray. Repeat step 6 until a
well-defined spray pattern has been obtained, then follow step 5.


Note: Photocopy page Appendix A to make written notes about the operating
pressure and material temperatures that finally produced a well-defined spray fan
pattern.
