Works great., October 26, 2011 By Walter Sigona "Walter" (Arizona)

I bought one second hand from a friend in 2005. I figured I could use it if the power went out. I never needed it, but I would go out and start it about every other month. I let it sit for about 4 years without starting it. All the gas evaporated it sat so long. I figured that it would be hard to start. I added some gas and it started right up.

most reliable, August 19, 2011 By rcase8

I have had one of these 5500 watt generators for about 8 years. it is the most reliable piece of equipment I have ever owned. Always starts on at least two pulls. I was especially pleased with it after hurricane Ike when I was 6 weeks without power. This thing ran as long as 14 to 15 hours on a single tank of gas. I worked 12 hour days then and I would shut it off in the morning to check the oil and fill the gas and go to work when I came home after 12 hours of work and 2 hours driving time it was still running and providing power. My only complaint is the sound level it is very annoying after several weeks of listening to it. So I did some research lately
and found a bigger quieter muffler on line and installed it myself it didn't make it Honda quiet but it took it from a scream to a rumble I can withstand. I find it helpful to block in the gas and let it die by running out of gas when it is going to sit for a long time. I also changed to a full synthetic oil recently I haven't had a chance to use it since but I am sure it'll do fine.I would recommend this to a friend, but I would also recommend the muffler change.

works like a champ!, May 9, 2010 By J. Hefford

I have had one of these is my garage for 3-4 years and never used it until a few days ago when we had a major power outage. Was about to get it started on the second crank with a little starter spray. This thing is LOUD (!!!) but does the job. Four 110 outlets and a 220, so you could run a refrigerator, lights, and whatever else you need. Most of the time, it's not a big deal to go without power for a few hours but you never know when you're doing to have an extended blackout. When that happens, this is really nice to have!

Power company on wheels, March 2, 2010 By Thomas Kaim "MrMou2U" (Lee, NH)

I've had the 5000 watt version of this generator for 8 years. The first six years it stayed in its unopened box as the power only went out for a day or two at a time and I was unaware how great it worked. Last year here in NH we had a severe ice storm and after two days of running down our supplies of water and wood for the woodstove, I decided to unpack the 6 year old Coleman Generator. I added oil and gas and it cranked right up, then tried running a few things with an extension cord. Having never used a generator, I found it just incredible that I could have power like this - ultimate power tool!

Long story short: the power outage lasted another 6 days (8 total); an electrician in-law helped me tie the Coleman into my sub panel; I had almost every convenience (phones and cable tv were out but hot showers, heat, microwave, laptops, lights were all available); fill up the unit at 11 pm and still running at 10 am.

When the oil gets to a level that is still ok but about halfway down on the dipstick, the unit starts to waver and then will quit running - go out there and add more oil and gas and it cranks right back up.

As I write this we are on the 5th day of another outage due to the Feb 25th 'Snowwicane' This time I cranked up the Coleman right away and I am able to run everything except my kitchen electric range and the clothes dryer.

The Coleman model that I have uses a 10 hp Tecumseh motor that seems to be extremely reliable and starts on the first pull every time.

The only con that I can think of is that adding oil requires a funnel and while the dipstick says not to over-fill, it doesn't indicate how many ounces need to be added when it is half full - seems like that would be easy to add onto the dipstick. Oh, and it's pretty loud.

My wife and I both resisted using the generator initially but now we're looking at a bigger one with electric start so that we'll hardly notice if the power goes out.

Highly recommended.

Good homeowner security for power outages, March 14, 2008 By Thomas H. Lawler (Everett, Wa)

I actually purchased one of these generators shortly after Katrina hit the gulf in prep for a natural disaster with an extended power outage. I've not had one yet where it lasted long enough to need it, but my brother ~10 miles away had one for a full week in Dec 2006 (and luckily had a generator). In Dec 2007 another county in my state had power out for a full week due to a main transmission tower coming down, so those things have shown me no one is invincible to power outages. The hardware stores quickly ran out of generators each time a crisis came, so if you're smart you'll not wait for the crisis to come before considering getting prepared.
When I began shopping for a generator, I quickly found the minimum power/price ratio is 10watts/$1. If you want one with features like electric start or over 8,000 watts (which is where electric start becomes standard), expect the price ratio to be more. I actually got this thru Costco who sold it for $550. They recently quit selling this unit (at least locally for me), so don't necessarily expect it there.
As far as it's performance goes, I just ran it for a couple hours to break it in with some space heaters plugged in for a load. It started for me within 2 pulls. I'm sure some would say it's pretty loud, but noise becomes of little significance to me after the power has been out for 24+ hours and I'm becoming concerned with things like the food in the fridge going bad, etc. This unit comes with 25 amp circuit breakers, so it actually can put out the continuous 5500 watts they say it can (whereas I've seen other generators labeled like "5200 watts" but have 20 amp breakers, so if you run the math 240V*20A=4800Watts). Since a generator like this weighs over 100 lbs, having the wheels so you can move it like a wheelbarrow saves your back. Otherwise the product description tells the rest and I see nothing unexpected to report.
If you're going to store a generator like this for long periods, they recomend doing the following before storing it to minimize problems: Use gas additives to minimize varnish buildup, close the gas valve and drain the carb of gas (or burn all the gas out of it), pour 1 tablespoon of oil into the engine thru the spark plug hole, and slowly crank the engine till it's on the compression stroke (so the valves are closed).
Since I'm pretty sure this can power anything I'd need in my house, I have no fear of a power outage lasting over 24 hours.

Reliable back-up power, September 10, 2011 By U10 Coach

I bought this after Hurricane Isabel and have not regretted it. In fact, it got used again after Irene a couple of weeks ago and saved my sister-in law's freezer full of food, among other things. With a liitle basic care and maintenance, this generator continues to perform like new 7 years later, with reliable and clean (waveform) power that is easy on electronics. It starts on the first pull and runs strong all day. As another reviewer noted, it is quite fuel efficient. It is loud, however. Tips for keeping the engine reliable:
- Run it every month (or every 4 to 6 months, if you are like me and forget)for 20-30 minutes to make sure you can count on it and to evaporate any condensation out of the oil, etc.
- Check the oil before running it and when you refuel it during extended ops. It only holds 26 oz and not much needs to burn off before the low oil sensor/cutoff switch trips.
- Make sure you check the oil on a level surface. Low oil will cause it to stop running and/or not start. Can't stress this enough.
- Make sure to run the gas out of it when you are done by turning off the fuel valve and lettting it burn the last bit of gas out of the fuel line. This keeps the carburetor from getting gummed up.
- Use Stabil or another similar product to keep the gas fresh (for 6-12 months, tops, depending on the product and how much you use). Do not use old/bad gas!
By the way, for the reviewer that complained about the "$600" 10hp engine - it sucks that you got a bad generator, but that Tecumseh 10hp motor alone goes for over $400 new.

Great generator for the money, June 17, 2010 By Mike (Florida)

I bought this generator after the 2004 hurricanes ripped through our area in Florida. This generator starts right up on the first pull every time. As with any engine, if it is not used regularly, you need to treat the gas for storage. If yours doesn't have one, put a fuel cutoff switch in the fuel line. Every time you turn the generator off, just flip the switch and let it run all of the gas out of the engine. If you do this, you will never have a gummed up carburator and it will always be ready to go when you need it the most.

Work Horse, September 6, 2008 By Roxanne M. Johns (Moreauville, Louisiana)

I put this generator thru hell, we ran it for 18 hours a day for 5 days when hurrican gustro came thru louisiana and it never failed us. we ran a 110 unit, tv,freezer,fridge,fan and when the heavy rains came i would plug in the 1.5 horse power pump on the pool to remove excess water. it was well worth the 649 i paid for it.

Power Back GT5250 3 years Excellent for the Money, September 1, 2008 By K. Guillory

Purchased a GT5250 real cheap because someone did not put oil in the motor and blew the connecting rod clean out of the engine with half of the piston. Put a shot block in it and it has run great for 3 years. Use it for storms in southern Louisiana - many times!

Works every time and powers everything necessary like the frig, freezer, pc, satellite, cell phone chargers, freezer, router, switch, lights, TVs, DVDs, and a whole bunch more including the water pump. Not quite like a Honda but great for occasional use for a few weeks a year.

Extremely fuel efficient and only have to fill up twice a day for continuous use.

Great machine for the money., October 24, 2007 By Charles A. Hall

I bought my machine from a guy who has to keep up with the Jones's. He bought a new Kubota brand, and I bought his Devilbiss. The machine works great! Only once, it wouldn't start, but I drained the old fuel, put in fresh gas, and it started right up. Pro's - It is a great machine for the money. Con's - It is a little on the noisy side, and a little too heavy to be called portable.

Good Generator, December 24, 2006 By A. Davis

Bought this generator over a year ago at Home Depot for under 400.00 at a clearance price.PROS:Has low oil shutoff/Rigid tires/2 110 volt plugs/1 220 plugs./low fuel consumption.Have ran this generator continuosly with 2 jobsite air compressors and 4 roofing coil nailers with no problems.Aiso had 3way hooked up charging 1 Milwaukee 3 bay battery charger and 1 V28 battery charger.CONS:Minor-Fuel shutoff is inline wing type/No oil level indicator glass/Could use 2 more 110 outlets.FINAL THOUGHTS:Have been well pleased with this generator as it has withstood all tests I have thrown at it.

Not bad.., January 23, 2006 By G. Szimanski (Michigan)

I own one of these bought from Home Depot. Price was EXCELLENT. May not be a Honda, etc.. But for 400 it is an excellent back up generator. It is made in the US. Starts EVERY time, runs nearly the whole house including the furnace.(No AC) (Will run Window AC). I keep the gas treated, run int once a month or so (As you should ANY gas engine, unless winterized) It is a purchase worth the money.

Well Built - but a bit loud !!, January 19, 2011 By trgo (Parrish, Fl.)

I have owned this 3500W Porter Cable unit for 6 years.
I bought it to use with my large camping trailer.
It is an excellent piece of equipment, at a good price,( $699 ) and it easily provides the rated output.
The advertised noise level is 70.3Dba, and it seems at least that loud.
The noise level when on idle control is very acceptable though.
This is not a particularly good unit to use around other campers. They will be unhappy about the noise.
For jobsite use, or emergency backup, this is an excellent machine!
For camping, a super quiet series Honda, or similar Yamaha, would be a better idea!
I now also have a Yamaha YG2800i (generator inverter unit), and at 60Dba (low idle) to 67Dba (rated load) it is a wonderfully quiet machine. You will pay plenty more for the Yamaha, ( or for a Honda ), but for your money you will get pure sine wave power, and GREATLY reduced noise!

Works great after repair., August 14, 2008 By D. Slayden (Western Ky.)

I bought this generator on when I received it the 120volt GFCI recep. would not reset. The nearest service center was 35 miles away and shipping back would cost a lot. To get replaced at the service center would have cost me for gas and time so I replaced it my self for $12.00.(Electrican 35 years) Still a great deal. I paid $691.00 for the gen. including shipping. Very happy with it. Idle control works great.

Nothing Wrong With It, September 24, 2007 By J. Nardiello (Illinois)

For the money its the highest quality generator I could find anywhere. Honda engine runs smoothly and starts on first pull every time. Highly recommended.

McCulloch generator 5700w, November 2, 2011 By AcePayday (USA)

I purchased this generator new for $630 from WalMart of all places and used it during a recent power outage that lasted 5 days. Once I installed the wheel kit and added oil (it comes without oil in it), I pulled on the starter rope twice and it fired right up. I ran it for five days straight, 24 hours a day, and it never once hiccuped. My unit has four 120VAC outlets for extension cords and one 240VAC 30amp outlet which is used to connect (via 10 gauge/4 wire cable with twist-lock connectors) to the plug mounted on the side of my house leading to the transfer switch wired to my main e-panel. This unit is a beast and much quieter than most generators. . It handled my deep well pump, refrigerator, oil furnace, TV, computer, microwave, toaster, can opener, e-skillet and lights in four rooms (about 3800W) at the same time without any difficulty and could have easily handled more. This unit saved our butts and made life almost normal during the power outage. I cannot speak highly enough about this unit and would recommend it without any hesitation to someone looking for emergency power backup!

Good little unit, February 26, 2010 By Derek Curlee (Yoakum, tx)

I have had this unit for about 5 years. I have never had any mechanical problems or electrical issues with the generator. It does have one issue I am not pleased with. The recoil start cover is plastic. The eyelit that the coil rope runs through came loose on the rope guide and allowed the rope to cut through the cover. When this happened the rope jumped the spindle inside and I had to remove the cover and re-do the rope on the spring loaded spindle. Easy enough, but a majot pain non the less. If that cover piece would have been metal, I would have no problems with this unit.

McCulloch 11HP 5KW Generator FG5700AK, January 20, 2008 By Steve Hendrix (Ohio, USA)

Very nice little unit, though used very little thus far. Now that I have a generator, we'll probably never have another power outage <grin>. This unit has plenty of power for emergency household use. It definitely sees a LOAD when my big deep-well water pump kicks on, but handles it just fine.

The only con I've seen thus far is that it floods easily. Choke it for one pull only (maybe two if it's REALLY cold). Otherwise it starts easily on the first or second pull.

Note that the picture Amazon is showing depicts a slightly more expensive model, with the side-mounted control panel. The one I received is the basic model, with the plugs right in the end of the generator, and no AC power switches. Just fine for my purposes, and the price was better than I've seen anywhere else.

What they said...., December 18, 2007 By Michael Burcke "burke" (Oklahoma City, OK)

The reviews above pretty much say it all...these are really excellent generators, especially considering the reasonable prices. Don't worry about the Robin engines...they are exceptional. I say this as a former generator technician. The only thing equal to these is Honda, but you'll pay for the priviledge.

Makita Quality Standards
, July 7, 2007 By R. W. Mayer

As anyone who has thoroughly done their generator shopping discovers, this Makita generator is not made by Makita, and is sold under at least three different brand names. Regardless, it does have the Makita label on it, and that meant something to me having owned many high end Makita tools for years, and having found virtually all of them as better choices than my past preferences of Milwaukee, Porter Cable, etc.

I have not used this generator extensively, so my findings are preliminary. So far, fit, finish, layout, components, etc. all appear high quality. The thing starts effortlessly and immediately and is super quiet. I had narrowed my choice down to this Makita and a comparable "middle of the road" Honda unit. The Honda unit was my first choice, but price dictated the Makita purchase. If this generator was in everyday use I would have likely gone Honda (never had a bad Honda product, and I own lots of 'em).

Although previous reviewers have discounted the Robin engine, I feel Robin's Subaru affliation, and past affiliation with Wisconsin engines ought to be worth something. For the price, the only other comparable units had Briggs and/or Tecumseh engines, both of which I stopped using decades ago after repeated sour experiences.

Only less than positive comment: The manual is cryptic. A bit better overview of uses of the various outlets would be good. Not necessary if you have good common sense, but you'd think legal counsel at Makita would mandate otherwise!

UPDATE 02/05/2011 The Makita G6100R has stood well over the test of time. This generator continues to start first pull...well not all of the time, but certainly 75% of the time...never a difficult start over the years. It also has more available surge power than ever anticipated. Whereas no generator I have used in the past was capable of starting my 120V 5HP split phase motor on a wood planer, the Makita will...not without complaining a bit, but indeed the Makita feature of being able to provide up to 150% of rated capacity for up to 20 seconds is enough to get the 5HP spinning....keeping that 5 HP running is literally no sweat.

I just finished running the Makita G6100R almost non-stop over the past four plus days as we have lost our power due to an ice storm. The Makita is wired into a transfer switch, and powers my 2HP 220V water pump, freezer, fridge, and sundry lights and outlets. It purrs along wonderfully, never even approaching capacity! My only "complaint" is a minor one...that is, when the generator is running under minimal load (but idle control has not yet kicked other words, still under some small load), it does not always running smoothly at full RPM. It will run perfectly smooth about 95+% of the time, but does occasionally miss a beat...just a minor blip. There is no real high speed adjustment on the carb (gotta love EPA regs which mandated this carb change!), so the engine pretty much has to run the way it was set at the factory. My complaint is a minor one, and may simply be a spark plug that is on its way out. I'll check shortly. All in all, I would buy this generator again, especially appreciating the price it is today, which has risen over 230% since my purchase! Better than my portfolio did over the same period...

An outstanding value, August 28, 2005 By David Gancarz (Central Florida, USA)

After weathering three hurricanes last year here in central Florida, we decided to take the plunge and invest in a generator. We were looking for one with enough power to run our refrigerator, ceiling fans, lights, television, microwave, computer, and miscellaneous small appliances (coffeemaker, fans, etc). We also wanted the machine to be portable so it could be stored in our garage when not in use and moved outside by one person when it needed to be run. It should be gasoline powered, relatively fuel efficient, and affordable. Finally, we wanted to be able to hook the generator into our house circuitry so as not to have to deal with extension cords. Connecting to the house circuitry meant installing a transfer switch for safety and to meet National Electric Code requirements. A transfer switch allows you to power essential, pre-selected branch circuits (refrigerator, living room, dining room, for instance) from either utility power OR generator power, but never both simultaneously. The transfer switch does the very important job of electrically isolating generator-powered branch circuits from utility service. Without it, you would be energizing service lines outside your house, creating an extremely dangerous condition; for instance, you could electrocute utility crews working to restore power. The transfer switch configuration also requires the generator to supply 120/240VAC power, which is what is used to power the transfer switch/subpanel.

For the list of items we wanted to power, 5000W is the correct size. A larger generator would be needed if we wanted to run our central air conditioning system, the hot water heater, and/or the electric range.

We visited the usual home-improvement-superstore suspects to look at 5000 Watt generators. TroyBilt and Generac are well under $1000 and certainly affordable, but they are made by Briggs & Straton and are of poor quality, in my opinion. I bought a brand new TroyBilt/B&S power-washer some years back and after about 6 months the seams in the plastic gas tank came apart, causing it to leak gasoline when filled more than part way. I bought a new Toro lawn mower with a B&S engine which suffered the exact same fate - the seams in the plastic gas tank failed. Perhaps I am just unlucky with B&S products. But for me, I am not interested in owning another one.

Honda generators were very nice and have a well-deserved reputation for reliability. However, they were just not affordable - at least to us. If I were a site contractor and was going to use it every day, then maybe I could justify the $3000+ cost, but certainly not for a machine that was going to spend most of its days sitting in the garage.

We settled on a Makita G6100R generator and I have been very happy with it. The 6100R is identical to the Robin Subaru RGV6100 -- evidently rebranded under the Makita name. It is powered by an 11HP OHV, 4-cycle, air-cooled Robin Subaru engine which, according to the literature, has an aluminum alloy block with cast iron cylinder liner, electronic ignition with automatic timing adjustment, dual ball bearing supported crankshaft, automatic decompression system, and splash type lubrication. The generator is brushless, self-exciting, 2-pole, single phase and generates 20 Amps on each of the two 120V output circuits for a total of 40Amps (20Amps at 240VAC). The 5-gallon metal gas tank will, reportedly, allow it to run under full load for about 7 hours. This generator is also available with an electric start (model G6101R). The one I bought (G6100R) has a recoil-type starter (pull cord). I had no problems starting it, whatsoever. It starts very easily. I also purchased the Makita 110004-A 2-wheel mobility kit, which I highly recommend. Without it, you are looking at close to 200 lbs of dead weight to move around.

I purchased a Gen/Tran PowerStay 200660 manual transfer switch, which allows me to switch up to 16 branch circuits between utility power and generator power. When in operation, the generator sits OUTDOORS and away from HVAC intakes (avoiding the dangers of carbon monoxide poisoning) and plugs into a Reliance PR20 power inlet box using a 10-foot L14-20 power cord (20A @ 120/240VAC). A 50-foot length of 10AWG 4-wire Romex runs from the power inlet box, through the attic, and connects to the transfer switch next to the main power center (breaker box). Basically, you start the generator, then switch the transfer switch to open the Utility breaker and close the generater breaker, thus supplying generated power to all the branch circuits wired into the transfer switch subpanel. A nice side feature of this setup is that when the utility power comes back on, power will be restored to those branch circuits not routed through the transfer switch (such as air conditioning). Therefore, you will know right away when the utility power comes back on.

Makita Quality at a Great Price, March 7, 2003 By NCisBeautiful (Durham, NC USA)

I decided to upgrade my generator from the 2500 watt Coleman I was using. It would barely run a refrigerator. We had a terrible ice storm here in Durham NC a few months ago. I was without power for three days and we were luck it was only that long. I did alot of research into generators. Here's what I found. Honda gens are wonderful but expensive. Grenerac is garbage for long term use. Read the reviews if you doubt. Makita built by Robin compare feature to feature and quality wise with Honda. I like the way Robin builds their engines, all ball bearing construction. No sleave bearings here. I have use this gen twice so far and it will power my whole house no problem. The control panel on this gen is well layed out. I used a outlet box with a twist lock plug to feed power into my main pannel. By the way Amazon has the best price on these gens.

Best Generator for the price!, February 26, 2003 By A Customer

Just recievd the Makita G6100R 6100 Watt Generator and was very impressed on how it worked. Filled with oil and gas, gave one pull on the starter cord and started to run. Ran my entire house on the generator (with a 20 AMP twist lock plug wired into my circuit panel)for 5 hours with no problems. Has great features normally found on higher priced models. Idle switch is great along with smooth and QUIET running Robin (Subaru made) engine. Can't beat the price either! Get the wheel kit, this generator is heavy!

Makita Generator 12/2/00, December 2, 2000 By John Bishop (N.Y.)

As a custom homebuilder, I have owned many different brands of generators including Honda, generac, coleman, yamaha, and John Deere. This Makita has been as good or better than any and is easily the best for the dollar. Especially well liked by my men is the auto idle feature along with the fact that even at open throttle this unit is very quiet, very important whe running 8 hours a day. The only problem I've had so far in 6 months use is a broken starter rope.

Small, efficient, reliable, June 5, 2011 By A. Murillo "Tony" (Sparks, NV)

Very impressed with this little powerhouse. Bought this new 6 yrs ago. Compared heavily to the Honda 3000EU. No regrets. The Honda was significantly more expensive. Goes with the Honda, brand strength and reliability. I'm a big Honda fan.

Decided that the Yamaha was built well and, though not as polished and finished as well as the Honda, has enough brand recognition and enough features, at a lower price point.

My use was camping, hunting, light construction. For my camper keeping lights lit and batteries topped off worked well. One issue is that my air conditioning would put too much draw and kill the generator. Not sure how many amps the draw was, but that was the only situation where it didn't handle the pull.

Still use it regularly, camping and hunting with no complaints. I really like the cage structure where the ends are handles and it packs very well where you can stack boxes on it. The choke works great, max pulls when cold is two. (very appreciated)

I usually run premium fuel, though it runs perfect on 87 octane as well. I most like the surge function when powering larger amp draw and the inverter function to power laptops and finer electronic equipment. I feel safe using anything with this generator.

I fully expect to be using this same unit 20 yrs from now.

FANTASTIC PIECE OF EQUIPMENT, February 10, 2011 By trgo (Parrish, Fl.)

This is a very impressive piece of machinery.

It has "low idle" ... for low noise (60dBA) when at idle, (67dBA when at full load) is an inverter unit with true sine wave power computer & TV ), and has a large gas tank for long run time.

These units have occasionally sold new on E-Bay for $999, with free shipping.

I was lucky to find one locally, with less than one hour of use, for $700.

I also own a 6500W Honda electric start unit, and a Honda powered 3500W Porter Cable unit,( at separate locations) but this YG2800i Yamaha is unique, in that it is small, can be carried, is quiet, and is very efficient.

So far so good, September 7, 2010 By yamahagenerator123

It is a lot smaller than I thought it would be. And noise is more than I expected in the non-economy mode, but not unbearable.

Added oil and gas and it started in one pull. Very nice. I did not plug anything electrical yet. Waiting for the next storm.

Adding oil is difficult as the handle bar is in the way. I had to turn the generator to its side and use a small kitchen funnel, still with difficulty to fill the oil. There are some errors in the manual for example one intro paragraph claims it's a diesel, although several pages later it explains that its gas, required octane ratings etc.

Great generator, June 14, 2010 By Dennis Hevener

We needed a medium-duty generator primarily for backup power for a small data center. We were impressed with the quietness of the Honda EU2000 inverter-generator, but chose this because of the larger fuel tank, lower price, higher output, and more rugged look. We have not been disappointed.

It sounds a little louder than the Honda, but is still way quieter than most small engines.

Inverters rarely put out a perfect sine wave, but this one is clean enough to run all of our equipment, including one piece that shuts down when operated from an auto battery and a "modified sine wave" inverter.

It was used for a ham radio field day -- a simulation of emergency operations. It ran 5 transceivers, 5 computers, lights, fans, coffe pots and the like. This is the first time it had been used except to test it in our data center. We ran it for 10 hours, then shut it down to change oil (always a good idea to prolong the life of a new engine) and fill the fuel tank. It ran about 16 hours on a tank -- it was at idle unless a couple transmitters were going at once.

After the 16-hour run, one of the motor mounting bolts had come completely off, and another was loose. So keep an eye on that. We used Loctite and hopefully that will take care of it.

Here is a PDF version of the manual:


Reliable, easy, lightweight, September 10, 2008 By P. Knapp (San Diego)
We bought this generator to power our RV and have had absolutely no trouble with it for 5 years now. It runs our AC unit and that is what we wanted. It is super easy to carry around, I can do it myself and I'm a medium sized woman. We did not buy a bigger one because of the extra weight and have never been sorry. If I need to use the microwave or the electric water heater, I shut off the AC and run the other stuff. It is pretty quiet when compared to other generators in camp and it starts up easily every time, no matter how long it has been. We usually find it takes a fill up on fuel after about 7 hours of running and does fine if you have to run it continuously for days at a time. We would buy it again, and recommend it to other campers.

Excellent generator, June 12, 2008 By Peter Schiller (Freedom, NH United States)

I bought this generator from Amazon about five years ago in order to build our house. It supplies plenty of power to start and run 15 amp saws, compressors, etc. Because our house site is about a quarter mile from the road and one of our neighbors was difficult, it took nearly 18 months for us to get power from the grid. During that time I would have to estimate that the generator ran for 2000-3000 hours. Today we use the generator just for emergency backup; it can handle two refrigerators, the circulating pumps for the heat, lights and the TV, all at the same time without any problem. This generator is relatively quiet, quite efficient, and very reliable. When we run it at slow idle, which is all we need for backup, it only consumes about 6 gallons of gas per 24 hours. Even after all of the hours that it has run, after sitting for six or more months without being started, the generator still starts with ease. I would buy this generator again without reservations.

Great tailgate and emergency generator, December 14, 2007 By M. R. Reynolds (Tulsa, OK United States)

I have owned the non-GFI exact twin of this generator for about 5 years. I use it for tailgates and as an emergency generator. This little dynamo ran continously for four and one half days this week due to an ice storm taking out power in Tulsa for around 250,000 customers all week. The generator was barely powerful enough to run my clothes washer and it couldn't get my gas dryer started. No biggie. It easily ran my gas furnace from a pig tail off of a switch, refrig., small TV, crock pot, laptop and a couple of small curly Q low wattage lights using heavy and not so heavy extension cords. Basically covering all of my emergency power essentials. This was using the economy setting on the generator. The generator had electric power to spare. In the early morning it even ran my Mr. Coffee. I only had to fuel it twice a day. All week long during the ice storm my friends were either freezing or scrambling to find a loud, heavy, low quality junk generator at a hardware store. Not me!

Great portable power, December 5, 2006 By Norm (Southern Illinois)

If you want a generator that you can carry by yourself, this is a good choice. It is designed to be light and quiet and meets those goals quite well. I think if you figure the Kw to pounds ratio, this unit will compare favorably to most of those out there. I don't know why someone would try to hardwire one of these to a house. For that, you need a much larger unit. I actually chose the consumer model, EF2800. It came with a longer warranty. I also did not want the GFCI because I've had problems with those types of devices tripping on the starting current for a freezer.

performs well, October 11, 2005 By Quick Smart (Elgin, Illinois United States)

I've been using this generator for one year without any problems. In the field, it powers delicate gear like mole and kino lights for video production, which require clean power.

Starts easy, runs quiet.

Just don't get it., September 14, 2004 By J. C. Gomez (New Port Richey, FL USA)

You know what, I just don't get it. Why on earth would anyone spend over a thousand dollars on something without really knowing what they were getting.

You have the first reviewer that complained about not being informed about the need for a transfer switch. Well, I hate to say it, but you don't NEED a transfer switch. You only need a transfer switch if you want to connect it to your home's breaker panel. You must do that regardless of generator in order to meet the latest code standards. You could just as easily run extension cords. They also mentioned about not knowing the NEMA code for the locking plug. Off the top of my head, I believe I was told it was a NEMA L5-30. Funny, I was able to get the information. A quick call to Yamaha would have answered the question.

Then you have the person that complained about the generator not being 240V. First, no where do the specs read that it outputs 240V; it only specifies 120V. Second, the NEMA L5-30 is only for 120V up to a maximum of 30 amps. Third, you could always hardwire a cable from the transfer switch to a male plug for the generator. That's just one solution . . . there are others. Fourth, I clearly read on the website that Amazon would not accept returns.

I would agree that providing a manual online would be nice, but dinging Amazon or Yamaha for an individual's failure to adequately research a purchase is not the fault of Amazon or Yamaha. I called Yamaha with questions and they gladly answered.

All I'm saying is be fair with your review.
