## Questions & Answers

**Q: This looks exactly like the westinghouse 4500 made in china.  is this different and is it made in the us?**
A: Same Generator, just repackaged under the Cummins name.   Save the money and get the Westinghouse.  I purchased the blue one recently and was impressed for the money. I also have the Honda 3000. This is much lighter and provides more power. The build quality is not as nice as the Honda and probably won’t last as long under commercial use, but for use here and there it is hard to justify spending 3 times as much for less power and only slightly louder. The same week mine came in I purchased one for my father.

**Q: So is the 3-year warranty automatic and then you add another 3-year warranty for 120 bucks**
A: The manufacturer provides a 3 year warranty.  Any other warranty purchase is from a third party source, such as Amazon.

**Q: Product specs say 50 Hz -- that's going to be a problem for many devices in North America, right?**
A: It isn’t a common American cycle, things may run on 220-240volt but not on 110v. Unless specified by the manufacturer to operate on both 50Hz and 60Hz, appliances may not operate efficiently or even safely if used on anything other than the intended frequency.

**Q: how quiet is it while running?**
A: just as good as my honda 3000iu gen. My second one of theses with 250 hrs on it without a problem, Good product for the money.

### ⭐⭐⭐⭐⭐ Tried and true
*by J***A on November 11, 2023*

I bought a Generac non-inverted 8500W EFI model from Costco and it wouldn't start so I returned it. Decided to give the Cummins a try. It's not the latest design, but right out of the box (after adding oil and gas) it started right up. It's so quiet, relatively speaking (it's not going to be the gathering place at your parties) and just purrs along. They don't want you running more than 50% load until it's ran for 5 hours, so I let mine run to that point before hooking it up to my 5th wheel. Turns out my 50A 5th wheel doesn't even use 50%, at least without running AC which I didn't try. My normal hookup is only 30A, so I have no concerns with this generator being able to supply my trailer. In fact, my voltage stays up at 120 while running on the generator, whereas it drops badly when running on the park power. Changing the oil is a bit of a challenge. The body panel that covers the oil area for some reason does not line up with the oil drain plug and it's a very tight space, so it's extremely difficult to get any kind of wrench on it. I just bought a swivel head ratcheting box wrench to hopefully reach it easier in the future. I love the luggage-style handle that lets you move it around easily. I'm in the gravel and on uneven ground, so a 4 wheel setup is a problem. Tilting it up by the handle and rolling it on 2 wheels works very well. I'm very happy with the purchase.
