Rated 4.1 out of 5 by 81 reviewers.
Rated 5.0 out of 5.0 by Great Power This generator runs great! It ran a 230V mig welder and a grinder and a work light while never missing a beat. November 24, 2014
Rated 3.0 out of 5.0 by easy to use overall satisfied with this generator. One problem is it is very loud. a lawn mower without a muffler is more quiet. Good for a construction site but for backup home use keep your windows closed and your T.V. turned up, your neighbors won't like it. October 28, 2013
Rated 5.0 out of 5.0 by highly recommended the generator was used on a job site for the first 30 hrs. Brought it home right before Sandy hit, i am 1 hour north of nyc so our area was hit pretty hard. we were without power for 6 days, but the Rigid made it feel like nothing happened. i Changed oil to synthetic before the storm at the 30 hr mark and it performed flawlessly. i ran it over 100 hrs and was very happy with its performance. the lcd also tells you when service is due.i changed the oil again and spark plug at 100 hrs. it is well built, gives out clean power as i run through the panel with an interlock kit. It was practically like power never went out. i find it to be top quality, i am impressed with the subaru engine. the design makes it easy to move and it is not as loud as most gens it size. in my opinion it is high quality and excellent value for a generator of its size.

Rated 5.0 out of 5.0 by Better than Expected Performance Just used it for 5 1/2 days non stop. (bought it less a month ago!) Did its Job Better than Expected. As others have mentioned - it is bit loud, but out-performs many other GenSets in the price range. PROS 1) Zero Gravity Handle works very well. 2) @ 50% load you can get 11+ hrs on a tank of gas. 3) Starts & runs like a champ 4) Excellent Suburu engine. 5) Nieghbors think it looks cool (no one complained about the noise) 6) Powered a 4,300 SQFT House no problem (did not use Electric Dryer and Stove at the same time) Cons (little to no impact in an emergency situation) 1) No Gas Gauge 2) A bit loud (But many others GenSets are too) 3) No Remote Choke Buy it - You WILL Like it!

Rated 5.0 out of 5.0 by Solid heavy duty feel The generator looks and feels heavy duty unlike the other models sold in stores. The design beats my friends honda. I like the zero gravity feature for the easy moving around despite the heavy weight of the unit. The engine started up without any problems at the first trail. The battery start is a awesome feature. Make sure and charge the battery prior the install and maintain the charge during storage. The unit is tastefully finished and nicely painted. I contacted customer support regarding the Subaru engine oil changes and type. I was told not to use synthetic oils. Also, for the breaking period I was told to use straight 40 weight oil for the first 20 hrs with heavy load on the generator so the seals and rings set properly. The tech support said that most of the people don't use the generator to it's designed capacity. The engine is not your typical engine, it is a commercial duty motor so it has to be broken in with heavy oil. After 20 hrs change to regular 10w-30 oil for the remaining life of the engine. Remember, this is not in the users manual. December 27, 2011
Rated 5.0 out of 5.0 by Definitely a good buy When my RIDGID 8000 watt generator arrived, I followed the quick set-up directions, pulled the cord through three times slowly to get fuel in the lines, hit the electric starter (battery came fully charged) and she started immediately. I do not think it is too loud. It is definitely well constructed and OH SO easy to move around. I called Subaru and it was suggested that I use "Ethanol Shield" in the gas. It is available at Home Depot. Question...has anyone actually used this generator during a storm when it had to sit outside in the rain? June 24, 2012
Rated 5.0 out of 5.0 by Great Generator, Fair Price, A Little Noisy I did extensive research on line before deciding to by the 8000. The selling points were a real voltage regulator, adequate power, and electric start. The Subaru engine helped too. This web site and the Ridgid web site don't have quite enough info so I called Ridgid for more. Among other things they told me that the generator has a Total Harmonic Distortion (THD) of 5%. THD is a measure of the "quality" of the power put out. Many/most generators won't mention their THD. I've called some, and even their tech support doesn't have this information. However, take it from me that 5% is very, very good for a portable generator. Some generators brands that pride themselves on good quality power have a THD of 7%. I'm making a big deal about this because it is important to have good quality power for electronics. Bad power quality can fry electronics or shorten their life span significantly. The web sites also don't mention the sound level put out by the generator. Again, by calling them I found out that the level is 76 (?) db at 70 feet. This is a little high. Some of the higher priced ($2500+) generators of this wattage measure that at about 21 feet. This is noticeable. The generator is a little noisy. Hondas for instance are noticeably quieter. However, if you want something quieter with good quality power be prepared to spend the 2 or 3K. The electric start works very, very well. I started the generator several times, in weather that was 11 to 18 degrees. It started every time in less than 2 seconds. The generator appears solid and well though out. The gas fill is near the edge of the top. This makes filling it much easier. The gas take holds 8 gallons. This should be enough to last 10+ hours at a reasonable load. I have a whole house transfer switch on my house. The generator basically supplies every circuit in the entire house (BTW, don't buy a 6 or 8 circuit transfer switch). With typical electrical load I got 118 volts throughout the house. With every light in the house it stayed there. With the 220 dryer on high I got about 116. The only time the generator sounded like it was working hard was when I turned the oven on. Even then the voltage stayed just fine (slightly over what the utility power gives me). BTW, the generator comes with a 20 amp cord. However, don't be fooled. This is NOT a cord for connecting to a transfer switch. You need a 30 amp cord for that. This generator has (to me) a useless feature that allows you to detach the control panel and put it in a remote location using the supplied cord. This might be useful on a construction job site, but ... December 10, 2009
Rated 3.0 out of 5.0 by OK but could be better I recently purchased this generator to replace one that was stolen. I did not want to pay out the money for a Honda again & only get 2000w. So I decided that I would like something with a little more punch behind it for a backup power supply for the house as well as small to large job's. Thing's I like. It is very easy to move around. The zero gravity is no joke. It is very easy to start, even with the pull start this is not bad. No worries if you get caught with a dead battery. I have not removed the panel yet but this was one of the deciding feature's that helped me with my decision. This is also a safety feature. Helps keep you away from the generator for small job's that you don't want to drag out a extension cord. The fold up handle is great. Rigid is very innovative when making tool's for the guy that doesn't have a huge garage or shop to store their tool's in. I own most of rigid's portable tool's & this is one of the reason's that I see what rigid has to offer over other makes. Quality is second to none. The generator over all doesn't look nor feel like a cheap generator. Fuel gauge is a nice touch. The control panel that count's the hr's & load at any given time is nice. I have not seen this feature in a machine of this size. Typically only larger commercial & industrial model's come with these option's. Help's you keep up on the engine maintenance for those who consider thing's like that to be important. Dislikes Adding motor oil is a joke. Location is very poor. Need's an extension tube & dip stick. No auto engine idle option. It start's up & goes right to a pretty good rev. I don't like starting motor's that are cold without letting them idle a little to allow the engine temp to warm up before getting crazy. This will affect the life of any motor. In addition without the auto engine idle feature the generator is not as efficient as it could be. So when your running this generator you probably want to have a few thing's to power up because you will be paying for power that your not using. I miss my Honda that had this feature. Only one key came with the machine. (come on $1299.00) Fuel seems to leak out of the fill cap when tank is full & you tip back to move around.(I need to check for missing gasket) Generator is pretty noisy. But it's not a small generator either. Overall. This is for the guy that need's a generator for all small to heavy duty application's. This really is a nice generator that in my humble opinion only need's a couple of thing's done to it to make it virtually perfect. For the most part I am extremely happy with the purchase & would buy it over again. I hope this help's those of you who are pondering on purchasing this generator. Rigid is a trusted brand.
