The spray pattern of this gun variable from round to flat
with all patterns in between.
In normal operation the wings on the nozzle are horizontal
as illustrated here. This provides a vertical fan shaped
pattern which gives maximum coverage as the gun is
moved back and forth parallel to the surface being
finished.
SIPHON SPRAYING
Set atomization pressure approximately 3,4 bar for
lacquer and 3,9 bar for enamel. Test spray. If the
spray is too fine reduce the air pressure or open
fluid control screw. If the spray is too coarse, close
the fluid control screw. Adjust the pattern width and
repeat adjustment of spray if necessary.
PRESSURE SPRAYING
After selecting correct size fluid orifice, set fluid
pressure for desired flow. Open atomization air and
test spray. If spray is too fine reduce air pressure. if
spray is too coarse, raise air pressure. Adjust
pattern width and repeat adjustment of spray.
Keeping fluid control screw in open position will
reduce fluid needle wear.
NOTE:
To reduce overspray and obtain maximum
efficiency, always spray with the lowest possible
atomization air pressure.
