3. Technical description
Universal Spray Gun "System HD": Spray gun for conventional atomisation.
When pressing the trigger, the preliminary air is opened first and afterwards the material needle is pulled back. In
this way the spray material passes through the nozzle. Closing takes place in reverse order. The material flow volume
depends on the diameter of the nozzle and the setting of the material pressure at the pressure vessel or material pres-
sure controller. In addition, the material volume can be controlled by screwing the adjusting screw in or out.
For more adjustment option, please refer to chapter 6 "Changing the spray pattern".

WARNING:
Material and air hoses, which are attached with a hose clamp, have to be secured with a hose band clip
in addition.

Observe the following safety instructions, in particular, prior to operating the spray gun.
WARNING:
Wear respiratory protection and work clothing according to the regulations when working with the spray
gun. Paint mist jeopardises your health.
˗ Wear hearing protection in the work area of the spray gun. The sound level of the spray gun is abt.
85 dB(A).
˗ Fire, naked light and smoking are forbidden at the workplace. When spraying easily inflammable
materials (such as lacquers, adhesives, cleaning agents, et cetera), there is a higher explosion and
fire risk.
˗ When spraying materials, do not hold hands or other parts of the body in front of the pressurised
nozzle of the spray gun - risk of injury.
