Easy assembly, easy to staret.

Assembly was easy, Cut out of box and followed assembly instructions. Instructions to prepare for running were very clear. Started with some difficulty, felt hard to pull to start. Second time I started it was easy. Tested it two weeks later and had no problem starting. has all the power to run what i need during power outages. Great product.

Improper Voltage and Frequency

First run under load. 260 volts and 62.4 hertz I would like the instructions to adjust this. No service in my area. I would have to drive 80 miles to a shop that may be able to adjust this. The current fuel prices don't allow me too make two 160 mile trips . They will not take it back because I have run it. Running it, is the only way I found out it was not outputting proper voltage and frequency. Does anybody know where to adjust the xd5000E voltage This obviously was never checked at the factory before it was sent out. I am capable to do this.

Safety Caution

This product worked fine However, I caution everyone to be careful when moving it There is no warning safety label concerning the use of a safety pin to lock in the handle. I found it only after it flipped up on me and cut off part of my index finger I was lucky that is all I lost I wrote to GENERAC and advised them of this issue but heard nothing back

right out the carton ,

we purchased this unit ,removed from the carton @the job site filled with oil that was provide from Generac and fill with gasoline ,hooked up to a outside project job trailer and ran the unit for 40.o hrs even in the cold weather it never missed a beat ,I am glad to have made such a smart purchase of a high quality generator ,originally we were thinking about renting because we didn't want the headache of having to have the rental company have to fix the unit or do repairs when we really depended on electrical power .thank you, Jesse f Rose president of environmental services plus ,Kaukauna wi

For the price, should have flat-free tires and covers on outlets.

I'm pleased with the overall look and the attention to engineering details. The generator appears to have been designed for ease of maintenance. I like the location of the oil dipstick, oil filter and the oil fill on the engine. I also liked the oil drain hose which will make it easier to not make a mess when draining the motor oil. I would have liked for it to have flat-free tires. This generator will be stored for long periods of time between use. I do not look forward to having to air up tires when I need to move it to where it will be needed during a power outage. I would have also liked covers over the electrical outlets to keep mud daubers from plugging the outlets with mud during storage. I have not used the generator yet, but overall I like what I see based on decades of experience as a railroad signal maintainer running generators at signal locations during power outages.

Perfect for us

[This review was collected as part of a promotion.] I've owned two Generac generators in the past (traded up) and always been pleased with their performance. Lately it's been harder to pull a generator for me, so when I found one with a push start I jumped at the chance. You're going to need some help with this as it is quite heavy but assembly was easy and after that I could pull it on my own. We typically run our sump pump and freezers when the power goes out and run a cord upstairs to plug in the fridge and charge our phones/electronics. I tested it out and it had no problem with that load. I'd compare the sound to that of a lawn mower, loud, but if you're inside it's not going to bother you. The start is a breeze, I can't believe all the pulling I used to do. I feel a lot better knowing that if the power does go out for an extended period of time, especially with winter coming up, we'll have everything we need to keep us safe and warm.

Good value

Haven't had a chance to use this yet but it was easy to set up and starts great, seems to run just fine. I've only run it for about an hour to break it in, my transfer switch should be done in the coming weeks so the real test will be when I power up the house with it.

Works every time

This Generator starts every time and I have had no problems in 2 years. Shortly after I got this unit I had shoulder surgery. The design of the unit allowed me to set a couple short pieces of 2x4 on top to straddle the fuel line and set the 5 Gallon gas can right on top over the fill hole using only one arm. The only problem I had with this unit was when I let the oil level get too low and the unit would not start without enough oil....good safety catch! I put oil in it and off it went without a hitch. I ran a refrigerator, small freezer, sump pump, well pump, furnace, TV, garage door opener, and some lights with no problems. I have used it several times now when we loose power here in the country and it has never failed me.

This Generac Generator has great features & runs everything I need when there is a power outage.

I bought my Generac RS8000E because a friend of mine said if you want a quality lasting Generator. Then Generac is the one you want. He said the quality goes in before the name goes on. I liked that, & I like the electric starter, large fuel capacity & long run time. At 8,000 watts It has more than enough wattage to run our home. It's easy to move around and it's nice to know it's there when I need it. Our power went off for 4 days this Aug 11th, 2020 from the big storm that went threw the Midwest. That's not going to happen to my family again. Thanks Roger
