Operation
Start-up
Before connecting to the mains supply, be sure that the supply voltage is identical with
the value given on the rating plate.
- Unscrew the container from the spray gun.
- Aligning suction tube. (Fig. 2)
If the suction tube is positioned correctly, the container contents can be sprayed without
almost any residue.
When working on lying objects: Turn the suction tube forwards. (Fig. 2 A)
Spraying work when working on overhead objects: Turn the suction tube rearwards. (Fig.
2 B)
- Set the container on a sheet of paper, pour in the prepared coating material and screw
the container tightly onto the spray gun.
- Put the machine down only on a level, clean surface. Otherwise the machine could tip
over!
- Adjust the spray setting on the spray gun.
Three different spray jet settings can be chosen on the spray gun, depending on the
application and target object.
Selecting the Spray Setting
Fig. 3 A = horizontal fat jet
Fig. 3 B = vertical fat jet
Fig. 3 C = circular jet
The spray pattern indication can be found on the front part of the sprayer. With the
arrowhead towards the boss on the tip.
Adjusting the desired Spray Setting (Fig. 4)
With the union nut (2) slightly unscrewed, turn the air cap (1) to the desired spray setting position. Then tighten the union nut.
WARNING! Danger of injury! Never pull the trigger guard while adjusting the air cap.
Adjusting the Material Volume (Fig. 5)
Set the material volume by turning the regulator on the trigger guard of the spray gun.
- turn to downside ----> lower material volume
- turn to upside ----> higher material volume
Spray Technique
- The spray result depends heavily on the smoothness and cleanliness of the surface to be sprayed. Therefore the surface should be carefully prepared and
kept free of dust.
- Cover all surfaces not to be sprayed.
- Cover screw threads or similar parts of the target object.
- It is advisable to test the spray gun on cardboard or a similar surface to find the correct setting.
Important: Begin spraying outside of the target area and avoid interruptions inside the target area.
- Correct (Fig. 6a). Be sure to hold the spray gun at an even distance of approx. 10 – 30 cm to the target object.
- Incorrect (Fig. 6b) Heavy spray fog build-up, uneven surface quality.
- Move the spray gun evenly cross-wise or up-and-down, depending on the spray pattern setting.
- An even movement of the spray gun results in an even surface quality.
- When coating material builds up on the nozzle (A) and air cap (B) (Fig. 7), clean both parts with a solvent or water.
