Figure 3:
Spray Beam Shape Adjustment
7. Adjust the width of the spray beam by using the nozzle cap adjusting
ring (1/1) to modify the distance between the nozzle cap (1/2) and the
nozzle (1/4).
—
turn clockwise
– wide spray beam
—
turn counterclockwise
– narrow spray beam
Attention!
Never tighten the nozzle cap adjusting ring too firmly.
If you tighten the nozzle cap adjusting ring too firmly, the nozzle cap is
directly positioned on the nozzle. Thus, the atomizing airflow is blocked and
the horn air becomes so strong that the air jacket cannot be produced.
The consequence will be a sputtering spray gun producing unwanted
clouds, see figure 4.
