I received the generator (WGen9500DF) about a month ago, unboxed, installed the wheels, feet and oil. Added fresh fuel and plugged in the battery. At first this unit wouldn’t start. After going back and reading the quick start guide I realized I didn’t turn on the fuel valve, My bad. After turning the fuel valve on I tried again. It cranked twice and fired up. The very first thing I noticed was it was much quieter than I expected. I am comparing this unit to a one year old much smaller Champion. I ran this unit for two hours just to give it some run time before using it as a backup power source for our house. Last night I finally had the need to use it. Power went out, forced are heat went out and the house got cold. Rolled the unit out of the shop and hooked it to my switch. Turned on the fuel valve LOL and it started in less than two seconds in -2 degree temperatures. This thing ran two full size refrigerators a full size freezer, my forced air heater and lights in the house for 6 hours, I was even able to warm up coffee in the microwave, all of this with no light dimming or flickering no problems at all. To say the least, I am very happy with this generator.
I purchased two of these generators at the same time and the same price. The price is good for the wattage. The generator was easy to put together. The engine oil is supplied with the generator. The one complaint with this, is that with the oil dip stick screwed all the way in, the supplied oil does not fill the oil to the full mark on the dip stick. It only fills to the low mark on the dip stick. I like to keep my oil level near the full mark, as over time, engines use a little oil. I have not put these generators to the test yet.
I needed a high KW generator and this is a great product for the price. It was super easy to set-up and get it running. I put it on propane and it started on the 2nd time from a cold start. I’ve only had it <1 month, but so far quite happy with it.
