Dari Smart 25/2500 Compressor. 2HP Single Stage, Max 116psi

From the picture, it has a pressure switch, a tank gauge, regulator and regulator output pressure gauge.

The compressor should run till the tank is up to max pressure (116psi) and shut off. What is the Red Zone pressure? Usually Red means Dead and it sounds like the pressure switch has a failure and is not shutting the compressor off before going overpressure.

Amazing that no manuals are available online, I'd use the contact form on their website to see if you can have them email you an electronic equivalent if it's available.

Closeup

1. Pressure Shutoff Switch -- Cuts off compressor motor when maximum pressure is reached to prevent over-stressing pump and components.
2. Main Tank pressure -- maximum level reached is controlled by Pressure Switch, operation in the red zone indicates switch failure.
3. Regulator Output Pressure Gauge -- Shows the regulated output pressure
4. Pressure Regulator -- Use the knob on the pressure regulator to set pressure on the Output Pressure Gauge, set to pressure recommended by tool or paint sprayer attached to the compressor
