4.2.2 Compressed air connection
The gun can be connected to all usual compressed air
mains with a pressure up to 10 bar.
The setting screws for setting the working pressure are found on the handle:
blue setting screw - spray air
red setting screw - press-out air (press-out speed)
The following applies to both setting screws:
Turn left
Turn right
Before beginning processing, the setting screws must be set regarding the medium to be processed and the coating work to be
performed. A test should be carried out on a suitable surface.
4.2.3 Progessing:
By pressing the trigger, a compressed air cushion is generated behind the tele-scopic piston and the cartridge is pressed out.
The internal working pressure is exclusively controlled by the adjustment of the setting screws and cannot be influenced by the
position of the trigger.
The gun is vented by releasing the trigger - the medium flow stops and a hissing noise is produced.
4.2.3.1 Seam sealing:
Guide the nozzle at a distance of approx. 4 cm at a right angle and vertical
to the seam. Pull evenly. If the nozzle is aligned at an angle, there is edge
spreading and an uneven spray pattern on the seam.
Art. 200898 Art. 113062
4.2.3.2 Surface coating:
Guide the nozzle at a distance of approx. 20 cm vertical to the surface.
By adjusting the spray air amount and material feed, an adapted spray pattern
can be set for the application case:
- A limited material flow gives finer structures
- Limited spray air volume and limited material flow gives narrower spray areas
The setting should be checked with spray tests.
