Spraying device and method for adjusting the spraying device

A spraying system, comprising:

• a spray head;
• a supply line connected to the spray head, wherein a pressurized working fluid is guidable via the supply line;
• a metering screw configured to influence a fluid jet emerging from the spray head, wherein the metering screw includes a first position for a first pressurized working fluid having a first viscosity and a second position for a second pressurized working fluid having a second viscosity, which is different from the first viscosity, wherein an amount of the first pressurized working fluid emerging from the spray head as the fluid jet when the metering screw is in the first position is a same amount as an amount of the second pressurized working fluid emerging from the spray head as the fluid jet when the metering screw is in the second position;
• and
• a pointer element having at least first and second markings corresponding to the first and second positions, wherein the pointer element is connected to the metering screw in a rotationally fixed, but detachable manner,
• wherein the pressurized working fluid is the first pressurized working fluid or the second pressurized working fluid.
