Very good constant performance

Before you start using the engine, you must first fill in engine oil. To do this, you have to unscrew the side panel and fill in almost half a liter of engine oil using the oil can provided.
Once that's done and the tank is filled, you can get started.

In the video you can see the most important things regarding volume, starting power for power-hungry devices, etc. We use the generator to operate a deep fryer, a refrigerator, two punch cookers and the lighting for the punch hut when the hut is not used in the supplied area. With a constant power requirement, the generator consistently delivers almost 4kW.
If you need a higher starting power, such as with an electric chainsaw or an angle grinder, then all you have to do is switch to turbo. Here the generator runs at a higher idle speed and can therefore react more quickly to power-hungry devices.
