Automatic spray gun A15 eco
6.3
Operation
To achieve optimal results, adhere to the following:
–
Rinse the automatic spray gun with cleaning products before commissioning.
–
Too-high air pressure causes unnecessarily high air consumption and too-strong atomi-
sation of the spray fluid.
–
The diameter of the hose for the supply of atomiser air must be 8/10.
–
Too-low air pressure produces an unsatisfactory spray pattern.
–
Select the lowest possible fluid pressure.
1.
Make sure that the control air and atomiser air connections are not reversed.
2.
Close the control air (connection "St").
3.
"Open" material supply.
Depending on the type of material supply, the "opening" of the material supply is car-
ried out
–
By opening the connection tap
–
By applying pressure to the storage container
–
By filling the material into a storage container (hydrostatic inherent pressure).
4.
Open the control air.
The fluid is sprayed. Generally, the adjustment of the spray pattern is now required (

Ä Chapter 6.4 'Adjusting the spray pattern' on page 23).
6.4
Adjusting the spray pattern
Air and fluid nozzles are available in various sizes. There are 4 different families:
n
Round jet – cone-shaped jet in front of the nozzle.
n
Flat jet – width-adjustable jet for flat-shaped application. Depending on the design, flat jet
nozzles can be adjusted to adapt steplessly to the work piece geometry or in 45° increments.
Adjust the spray pattern with the following measures:
Change the atomiser air pressure.
n
Change the pressure of the spray fluid.
n
Select another nozzle size.
n
Adjust the needle stroke (optional) (
n
setting' on page 26).
