Adjustment
This professional spray gun features 3 controls:
Spraying fineness
•
Air is fed by the central air.
•
The air is adjusted by means of the air regulator mounted upstream of the gun on
the network and more precisely by means of the knob at the bottom of the gun
handle on some manual guns.
Fan width
•
Fan width is adjusted by using the knurled knob.
•
It controls the air going to the horns on the aircap. In this way, the air is controlled
through the fanned air outlets and allows the fan to change from flat (wide
open) to round (closed).
Fluid output
•
Having selected the proper fluid nozzle / needle assembly and the fluid pressure,
it is possible to:
•
Further control the output by changing the travel of the needle (using the needle
stop knob).
•
Optimal set-up is usually obtained when the fluid needle is completely open.
•
When this needle is nearly closed, a constant flow of fluid cannot be
guaranteed.
