Low-oil shutdown automatically safeguards engine from damage

Covered outlets provide added protection from the environment and rugged working conditions

Hour Meter tracks maintenance intervals.


1-¼ inch hardened steel tube cradle for added durability and strength

Rated 2 out of 5 by from hard starting In cold weather the only way it will start is with a spray of starting fluid into the carburetor..

Rated 4 out of 5 by from Great powerplant but poor fuel cell I've really enjoyed using this generator when its working. However, rust has developed in the gas tank and it has been nearly impossible to remove. Replacement units are all over $100. Maybe a plastic fuel tank would have been a better solution??

Rated 4 out of 5 by from GENERAC for Hurricane Power Loss I purchased my GENERAC RS5500 about four months ago before Hurricane Irma was to come close to my home in Coastal North Carolina, but I did not get to use it much other than initial start up and a few start ups since. We had an unusual snow storm yesterday, and when we lost power, I pulled my fairly new GENERAC RS5500 out of my garage attempted to start it up. I was disappointed that it did not start after multiple pulls. I referred to the troubleshooting guide in the manual to ensure everything was good, but was still unable to start the unit. After about an hour, I almost gave up and was read to call the product help center, when I figured I would give my GENERAC RS5500 one last try. It started on the first pull. I ran the unit for over an hour to ensure there were no issues with the fuel or engine. I'm not sure why I had issues starting the generator when I needed it, but can only assume it could be related to the fuel sitting in the system over the past several months. I did make sure to use only "ethanol free" fuel, per the salespersons suggestion, but that did not make a difference. I purchased the GENERAC RS5500 after reading reviews of the product and was impressed by the quality and dependability, which are most important to me. Also, as a military veteran and patriot, I wanted to own a generator that was made in the USA rather than in some other country. Although I was rather disappointed that my GENERAC RS5500 did not start when I needed it, I'll keep it and do my best to start it each month to keep the fuel fresh and flowing through the system. I hope to write another review after the first year to let everyone know about how pleased I am with GENERAC.
