A reliable generator is essential gear for contractors, but it's also important for home owners, campers, RV enthusiasts and others who may face planned or unplanned power needs. The Generac 9777 4,000 watt extended-life generator is just such a tool. The generator is ideally suited for either occasional or everyday use. A rugged, 7.8-horsepower overhead valve industrial engine provides 4,000 watts of reliable electricity and up to 13.5 hours of use on a single four-gallon tank of fuel. The unit is versatile and easy to use, with two 20 amp 120V power outlets, one full-power 30 amp 120V twist lock outlet, and one full-power 20 amp 120/240V twist lock outlet. It also comes with charger cables for recharging 12V batteries. The engine runs quietly and is designed with several added smart features, including an oversized dual element air filter, an automotive-style oil filter, and full-pressure lubrication. It also features a pressurized low oil shutdown system, automatic idle control, and a power surge alternator that protects against power fluctuations when starting and operating several motor-driven items at the same time. --Carl Thress ...

4000XL Easy on fuel once started
I purchaced this generator as a back up unit for my home and for camping. It is fairly quiet and real easy on fuel. There is plenty of power for running the AC and anything else at the same time in my camper. Unfortunatly it is very, very hard to get started in cool weather. I have to remove the air filter and use starting fluid to get in running if it is below 50 degrees. The unit has only about 8 hours on it so far and I hope this will get better as it breaks in. It comes with a extra air filter and spark plug (which I tried changing) but didn't make it better.
If it was a better starter out in cold weather I would give it 5 stars on its capability and price. This seems to be a complaint I have read before. That's a big down fall.

Update 11/03: After having this generator for 2 seasons I would like to add that starting has been getting better. I called the factory on the inital problem and they refered me to a local servicer. I didn't bring it in though because he couldn't gaurentee free service and had a 45 day wait to get to it. I don't have to go to extremes to start it anymore but I do have to hold the throttle closed for the first 2 pulls and it will usually start within a couple more even at temps down to zero. Running Mobil one oil seems to have helped too. Overall I am happy with my purchase and haven't had any other problems in about 100 hours of use.

Timing is everything
Having lost power for 24+ hours several times and for shorter periods almost monthly in the past two years, we decided it was time to purchase a generator. About the time it arrived, the weatherman started talking about this little storm called Isabel. Thank goodness for prompt Amazon shipping!

The generator is easy to start, runs smoothly while powering our refrigerator, sump pump, and TV, is easy on gas (used about 3 gallons for 10 hours so far), and came with everything I needed except grounding wires and gas. I usually have to pull the cord about 3 times to get it to start, but that is not bad in my opinion. I do agree with the review that stated the front leg and handle stop are a bit cheap, but I don't foresee putting it to the test the way that reviewer did with his business use and his fixes seemed pretty easy.

If we run into any problems, I will edit this review but so far it has been a solid performer at a good price.

faulty oil pressure switch
WE bought this generator as a emergency power unit about 3 yrs ago.we have run it for a total of maybe 40 hours.the last time we used it,it ran for 1hr. then shut down. would start right back then do it again. unit is full of oil.unpluged oil pressure switch now it will run. this unit is not very quiet but still quieter than some coleman generators.factory should include extra switch and symptoms of this problem in manual.

Commercial Grade
I recently purchased my Generac 4000 EXL for my RV. ( Also for my home, in the event of rolling power black-outs. The product is very sound in design with big generator features at a economical price. I especially like the pressurized oil system for the engine as it will extend the life of the engine. The electric start is a "must have" for a portable generator. (even more so for a RV) The automatic idle control is great and helps with noise control. (The unit tends to be a little noisy when under a heavy load.) The generator is compact and can easily be stored in the RV.
I have found the generator to be able to handle all my power needs. Even when the AC unit is turned on the Generac 4000 handles the power needs without problems.
One note:
I did purshase a three year service contract on the unit just to take care of any problems. So far I have had no problems with the unit.
I highly recommend this generator...

Runs like a champ
I bought this generator from Home Depot about 5 years ago. The longest single use I got out of it was for a week with hurricane Isabelle-it paid for itself. Other than that I probably run it 30 hours a year. I use it to power a 1.5 hp well pump, a refrigerator and the blower on my propane hot water heater. We can shower, flush and eat-the important things in life! These three things max it out but get us by. It could have a better wheel/handle design-it's hard to move around. I had to replace the carbureator (water got in and froze up-my fault) and a low oil pressure switch. The filler cap/gas gauge was useless and the low idle mechanism is screwy. I added a screw-on oil filter, which it didn't come with, although later models do. It runs like a champ. If it meets your needs I'd buy it. I'm presently on backorder for a 10,000 watt, 18 hp Honda engine generator. My suggestion to anyone buying a generator is-get the chart that comes with generators and figure out in advance what you want to power and buy accordingly. Good Luck! ... Read more

Poor quality and support
I purchased this power washer approx. 18 months ago, have used it less than 30 hours total and maintain it perfectly. It is used just for home use. I just noticed a leak between the pump body and the head. Upon inspection I noticed water had even leaked into the pump body contaminating the pump oil!! I drained everything, got to looking at my parts diagram and disassembled the head from the pump body. The diagram lists a simple 3 O-ring and gasket kit that turns out they want $150 for!!!!!! You have got to be kidding me! I submitted a request through the Generac e-support site and was told 'ya that sounds right'.

The Honda engine is tops, but a power washer is kinda useless when the pump is a piece of junk, and you are taken for a ride when you do have problems.

Outstanding Washer
I have owned this Pressure Washer for 3 years. I use it in my business. I have logged over 200 hours on this unit with not one problem. Very easy to start, uses fuel efficently, quite, powerful. I highly recommend this unit. The Honda engine is the best. The Italian pump performs flawlessly.

Very Poor Customer Service
My Generac Pressure Washer broke over 4 times in the first 6 months. Every company can have a problem with a product and this is where customer service is tested. The first warranty shop worked on the unit for about three months. The pressure washer had a problem with the unloader. Some times it would have high pressure and some times it wouldn't. The second waranty shop told me that the pressure washer had a design problem with the unloader and the wand and generac had new valve assembly. Why didn't they put the new design valve in months ago.

Well I spent 6 months driving my generac pressure washer to the repair shop for a problem that could have been recalled. I know that the generac people sent out wrong parts and they gave me a hard time about the warranty repairs when the whole time the unit had a design problem.

The unit did start first pull until it had been worked on a couple of times.

I can only judge my generac pressure washer by the performance, quality of repair work, and quality of generac factory customer care service. I was very happy to get out from under this unit.

I can now compare the performance to a new 3500 psi, 4 gpm, 13 horsepower brand x unit. The cleaning performance is better. It always starts. It hasn't broke yet so I can't tell you about customer service. The only negative is my new unit is heavier so it is harder to lift up into a truck.

If the factory customer sevice wasn't so poor I would probally still be nursing the generac pressure washer around. I got tired of wasting my time and purchased a unit that is superior to the generac in all regards except it is heavier. It is amazing how much better it cleans.

I should have scraped the generac the first time it broke.

Works better than advertised!
I just received this last night and did the minor assembly in 15 minutes. What took more time than anything else was adding the oil because I did not have a long narrow funnel. Outside of adding some gas and taking my time to read the directions and safety info., I was cleaning things in less than an hour. It works great! This Generac 1418 compares very favorably to the near new Landa 3.5GPM, 3500PSI pressure washer I rented from Home Depot. Considering that the Landa costs almost double new, this Generac unit is an excellent value! ... Read more

Generac Portable Products 8" Economy Generator Wheel Kit
This wheel kit is easy to install. The instructions are clear and simple. The parts are well-made, as is the Generac generator on which I installed the kit. The seller was extremely prompt in shipment, with the kit arriving prior to the promised date. The only recommendation I would make for the product is that the handle be a hinged model, similar to the handle which comes installed on the 3500 Generac generator. As is, the fixed handle takes up an extra 2 feet of storage area. For this reason, I didn't permanently mount the handle. There is a "fancier" wheel kit available, but the extra cost hardly seems worthwhile for the little difference. I would highly recommend this kit to anyone with a Generac generator. It certainly beats carrying it around!! ... Read more

Uncovered
This cover is NOT heavy duty vinyl as advertized. It is a weave, breathable, lightweight blend of some sort. It offers no rain protection. I tried "Scotchgaurding" mine but it didn't make a noticeable difference. It fits well though and should keep the sun away from the parts. I was expecting something a little more heavy duty that offered protection from all of the elements. ... Read more

PROFESSIONAL CONTRACTOR
I OWN ONE OF THESE ALTHOUGH IT WAS PURCHASED AT A LOCAL STORE IT IS THE GENERAC PRO 3500 PSI 4.0 GPM UNIT JUST AS THIS ONE AND IT DOES HAVE THE CAT PUMP ON IT I ASURE YOU AND OUT OF THE THREE PRESSURE WASHERS I OWN IT IS UNDENIABLY THE BEST. GREAT BUY

very good unit
I've owned this washer unit for about 1.5 years. Never had a problem with it. It always starts on the 1st or the 2nd pull. Very easy to find parts (air filter) for it.

CAUTION!
This is an old version of the Generac Pro Series 3500psi 4gpm unit. It does NOT come with the good CAT pump like the newer model does.
Stay away from this, no savings in the old type pump. ... Read more

Briggs & Stratton Reliability
I purchased the Sears Craftsman version of this item that is rated at 2000 psi and 2.0 gpm. The Sears unit also came with the turbo wand and extra oil for $199. Engine started second pull and has continued to do so. Its clearly for residental use not commercial, but does a lot of things very well. Do read and follow the instructions closely about purging air before startup. CONS: Engine/pump gets very hot and will kill grass where it sits. Engine will not empty gas tank. Stops running at about 1/4 tank and requires refill. I'd have it repaired under warranty, but its too darned reliable to have somebody messing with it.

Amazon Sucks
I ordered a new pressure washer and you sent me a used one with oil all over the inside of the box. I'm pissed. I thought that a web site like amazon.com would not go so low as to dupe a coustomer. I am returning this item and I will not buy anything else from Amazon.com. I will tell all my friends that ask me what I think about amazon.com, not to buy anything from them. Even thought shipping this pressure washer back will cost me the shippihg, it's OK as long as I get rid of this peice of this thing. I'm am very disspointed with this service.

Good, But Not Perfect
I recently purchased the 1694 from Amazon. The first thing to note is the item description. The engine that powers this unit does not employ OHV as Amazon states. I was disappointed since part of the reason for purchase was the OHV engine.

PROS: High PSI at slighter more weight than an electric unit. Easy to use. Very portable and stable on its rubber feet. Tried and true Briggs engine (The old lawn mower type.)

CONS: No wand/hose storage. Poor grade rubber hose, tends to kink easily. Gas guzzling engine for its size. Starting engine requires several pulls even after priming.

Summary: All in all this is a great inexpensive alternative to large pressures washers. For slightly more than a good electric washer you get the power of gas in a slightly larger form factor. This unit cleans /w ease, my only complaints are those listed above. ... Read more

The title describes the wheels as being 10", but in the product description they claim to be 12". We ordered this for a Genrac 4000XL Generator.

Generac Portable Products 1276 30 Amp 6 Circuit Power Transf
Great product. Easy to install. If you look at the front side of the unit you will see the UL label. Get some reading glasses John from Florida.

POWER!
Being only minimally eletrical, I installed this unit with ease. My only problem was the reach of the supplied PBX, but I safely worked around that. Last summer I used the generator with extension cords for power outages - a real pain compared to the transfer station. This fall, when the low has been 8°, I sleep a bit better knowing that I have easy backup power. I gave my kerosene heaters to my son.

Model 1276 is UL Listed
Just installed one of these Power Transfer Unit With A Generac 4000XL Generator . Great Installion Manual and Product.

Manual Transfer Switch
The transfer switch is the best device to use with a portable generator as a emergency home-back up system. The system is UL 98 approved and allows the customer to use the generator without having to open up windows and run extension cord thru. The unit allows you to monitor your loads when applied to the generator. It allow you to operate 6 circuits in your home, without having the worries of back feeding into the utility lines or hurting the generator with to many appliances hooked up. This gives me a big peace of mind, knowing that my family will not be without power and my portable generator is being used properly.

NOT UL LISTED
IT IS VERY HARD TO GET ONE OF THESE INSTALLED BY A CERTIFIED ELECTRICIAN, BECAUSE IT IS NOT UL APPROVED. OH SURE, YOU COULD DO IT YOURSELF ( OR CAN YOU ) BUT WHY NOT GET ONE THAT IS UL LISTED? THERE IS A REASON THAT CODES EXIST. YOUR SAFTY IS AT STAKE. ... Read more
