OPERATION
This Craftsman Detail Touch-up gun should be flushed with
solvent prior to spraying with paint.
A. Adjust air pressure to approximately 30 P.S.I. The
use of an air regulator assures clean, dry air.
Turn needle adjustment screw out until first
thread shows. This places the tip and needle in a full
open position which gives maximum tip and needle
life. Never turn all the wav in. as trigger cam will
break.
Turn fan adjusting screw out until first thread shows.
Press trigger and adjust needle adjusting screw for
desired material flow.
Press trigger and observe atomization of fluid. If it is
too great, decrease air pressure at regulator. If it is
not enough, increase air pressure at regulator.
Press trigger and adjust fan adjusting screw until
desired pattern is obtained. A perfect pattern is a
full, even coat from end to end. Each time needle
adjusting screw is adjusted Step E should be re­
peated.
