The gas generator shuts down under load

Maybe the starting currents of the milking machine are large? We must try a generator with a higher power. There is some kind of engine on the milking machine, its starting currents will most likely turn off the generator.

Is the generator good? Or "Chinese", if so, then its watts can be "Chinese", which means that it will not hold a load of 1.9 kW.

The question is the following - is it possible to connect the device to the network for testing?

To reduce the starting currents, if possible, you can pre-spin the engine, for example, by winding the cord around the shaft and pulling it, then press the power button.

There is also a possibility that the motor windings are punctured, that is, an inter-turn short circuit or short circuit to the case.

By the way, before you connect the load, the gas generator should work a little and warm up. Also, the engine can stall even due to poorly adjusted valves, a bad spark plug, carburetor, and even a clogged filter and fuel valve. That is, the problem of the internal combustion engine.

It's just difficult to give an answer without seeing the whole situation.
