My first port gen.....

Seems fine so far but we have only serviced it and started it for a test run.

Great product

Was shipped quickly, easy as pie to set up, and started right away. Just needs to warm up before trying to use with bigger equipment. Once its going for 5 mins or more then it is perfect. Not too load either. Would recommend to a friend.

Cool Purchase

30 minutes to install wheel kit, added fuel and oil, started on 3rd pull. Good unit for our emergency back-up power for our home! Would buy again... However, I would change the plastic oil tag located on the oil spout. It says fill with 30 WT oil. I live in Wyoming and this generator does NOT use 30 WT oil for this area...

Great generator 4 price

Bought on sale after bad storms rolled into nc. Wish i had 4 stroms but ready now. It came in 3 days with no damage. Put oil & gas in it started on first pull. Ran my air compressor and some small appliances with no problem. Need to get wheel kit for it so it will be easier to move but can move like it is. Well worth the asking price but was even better with 100 dollars off. Built solid and pretty quiet compared to other generators of same size & price.

Looks good and it works

Got a super fast delivery on this product. Unpacked it and had to wait a day to check it out. Removing the shipping braces in the bottom of the unit can be tricky because the nuts and bolts are really tight (thats good) but the metal used to make these particular four nuts and bolts is just a little on the soft side and care must be used that a good wrench doesn't strip the shape of the corners on the nuts when removing. Be sure to read the manual prior to starting. I put the unit on the deck and funneled in some oil (It says it holds a quart but be sure you don't overfill with that quart). I then set up a ground wire and installed a quart of gas. I just wanted to do a test run and didn't want to leave gas in the tank when I stowed away the unit. I found my good heavy load extension cord and a double burner hot plate that had been stored in the garage for too many years. Next I set the gas valve to open and put the choke lever to choke, flipped the red rocker switch for engine start / stop operation then moved the breaker flip switch to the on position and pulled the starter cord. One pull with the choke on and it started right up. I flipped the choke to the off position and it was crusing. I hooked up the two burner hot plate and varied out the burner operation as I ran one burner on its limit of med, then the other burner on high and watched both burners get red hot. It would vary the speed of the generator as I tinkered with the hot plate switches. That particular hot plate information show it draws 1750 watts. I had it on most of the time and the quart of gas lasted about 20 minutes under that load. It looks good and it works fine. I didn't order the wheel kit and was able to lift and slide the unit as needed but sat it on another wheeled unit (that I already had)and it works pretty good for now, but I may order the wheels kit and cover later. This unit measures appx. a compact 17.5H x 17.5W x 23.5L and is a neat fit in a cozy corner. (I am currently storing mine in the dining room) The price was $370 with free shipping and it turned out to be a pretty good deal so far.

Great little generator

Shipment arrived a little late but then again everything including FedEx was messed up because of Hurricane Irene. I unboxed this generator. It is easy to lift and move. I didn't purchase the wheel kit and don't plan to. I did not start it as I don't want to put gas in it and leave it for a long period of time. Be sure to get a quart of 10w30 motor oil. It is not supplied. I am hoping that I don't need it, but I am sure it will be great when I do.
