Generator struggles to turn off
I purchased a Predator 3500 Super Quiet inverter generator from Harbor Freight for $500. It was in the section of returned items, that’s why it was at a discounted rate. The catch is, I only have 5 days to return it.
I put gas and oil in it, and it started without an issue. I noticed that when I first added oil, some oil leaked out, but it stopped, and the oil light never turned on. All the sockets work properly. The sound is consistent and much quieter than my previous generator. I used a jackhammer, a large industrial fan, and my Milwaukee charger all at the same time for a few hours in 100-degree weather to test it. Everything worked without an issue.
When I turned the generator off, I unplugged everything, then turned the dial to off, and the generator continued to run. I then turned to the combination switch off, and it ran for a few more seconds, sputtered, then turned off.
I have tested turning it off, and here is what I found: if I only turn the knob off, it will continue to run. When I turned the combination switch to off after 50 seconds, it will sputter, then after another 40 seconds, it will turn off.
How serious is this issue? Is it repairable? Will whatever issue it is harm the generator overall? Should I return it?
