Instruction

1. To test the quality of paint spraying take spray gun and in a mode of sputtering, quickly along any wall or surface. If droplets of paint distributed across the painted surface evenly, so the quality of spray paint is in order. Spray the paint at a minimum pressure in order not to lose too much paint in vain.
2. To determine the correct shape of the imprint of the torch, turn on the spray for a few seconds and then go off to explore obtained on the surface of the print. If you notice that the paint is sprayed too much, then the spray gun delivers an excessive amount of material on the wall.
3. The imprint of the torch should be free of irregularities, depressions and visible violations. Balance the ratio of paint and air supplied to the space gunom to adjust the print.
