How to change oil and air filter for Kipor kde7000 also, I saw Deasil liking below the generator then later stoped by itself

When you load a generator it should increase in speed to compensate for the voltage drop, is it increasing in speed?

I would try disconnecting the oil pressure sensor temporarily to isolate that circuit as the possible cause of it shutting down.

looks like you need to change the oil

Im taking it as the engine is cutting out?
Is this a diesel model?

Try, low oil cut off, fuel tank not vented correcly, fuel blockage.

First check the oil, A low oil sensor will shut it down if more than a quart low. Then drain your water separator and change fuel and air filters. Anything outside of that is going to be mechanical (lift pump, injection pump)

is it air bound , clear it out , or you have a short but I would go with the latter ,

Your oil level sensor is bad. It needs to be replaced. If you unplug the wire leads to the sensor you may get the generator to run, but you'll have no low oil level/pressure protection. The oil level sensor is on the engine crankcase usually near the oil level dipstick. You'll likely see a small sensor with a couple of wires attached to it. To replace it, you'll need to drain your engine crankcase before removing the sensor.

1- make sure the air filtr is clean
to make sure the problem is not from the air filter run witout air filter
2- there must be a ajustabe screww which controls the amount of fuel out put from the injector turn that screw and see the result .
3- make sure the engin is not burning oil . by checking the level of oil every 6 runing hours you can figuer this out
4- some smoke is normal with dissle engines

Check the battery voltage while cranking the engine if it drops below 9 VDC then you have a bad battery.

Hi,
I just guessing here but it could mean that the oil pressure is too low.
I'd check the oil level first, then look for the oil pressure switch and temporarily disconnect it.
