When the compressor is connected by the hose to the airbrush gun, it can be connected to the
mains and switched on.
The maximum pressure is displayed the pressure gauge, the operating pressure can be ad-
justed by the pressure regulator.
The hose included in the delivery is air-tight.
Leakage check
Switch on the compressor and wait until the maximum pressure has built up.
If there is no leakage, the pressure gauge should display nearly constantly the same range of
pressure.
A quick decrease of the range of pressure suggests that there is in fact a leakage.
It is of great importance to seal any leak as soon as possible in order to avoid any impact on
the capacity and efficiency of the compressor.
Difference between maximum pressure and operating pressure
The maximum pressure is the highest possible pressure that a compressor is able to generate.
The maximum pressure is the pressure measured only inside the compressor itself.
On the outlet of the compressor, there is a lower pressure. What remains is the pressure that
you actually work with. The operating pressure may vary according to the connected airbrush
gun.
