inlet.
7. Connect compressed air hose [2-14].
7.1. Adjust spray gun inlet pressure
Note!
• Pull the trigger fully and adjust the spray gun inlet pressure (see
chapter 2) following instructions of one of the followig sections ([3-1],
[3-2], [3-3] to [3-4]), then release the trigger.
• With [3-2], [3-3] and [3-4], the air micrometer [1-13] has to be fully
opened and in vertical position.
• If the required spray gun inlet pressure is not reached, the pressure
at the compressed air circuit has to be increased; too high pressure
results in too high trigger forces.
