To start spraying, open the liquid tap. The Pulsfog will then immediately start atomizing. During spraying, the motor frequency may change slightly under load. In that case, reset the carburetor. In most cases you do this by opening the adjusting screw a little further. If you want to interrupt the misting process while the engine is running, close the liquid tap.
During atomization, the Pulsfog consumes gasoline. If the gasoline level has dropped to 1/4 or less, keep the unit as steady as possible and do not point the Pulsfog more than 45⁰ up or down. This prevents air from being sucked into the fuel line. An air bubble can cause the engine to stop.
