By Charles T. Binder on May 28, 2011
Brand new generator out of the box no apparent damage. I filled it with oil and gas, connected the ground terminal with 12awg ground wire to a building ground. Started the unit and my ground detecting surge protection equipment went into alarm and my APC UPS would not charge. Greenlee GT-10 circuit tester indicated open ground. Installed ground rod into earth and connected to unit. Open ground still indicated, but APC UPS proceeded to charge and there were no ground failure alarms.

Called Buffalo Tools customer service (866) 460-9436 as directed in manual and was informed 'you can't use a circuit tester on these generators they have an open ground, that's how the low oil shut off works. The unit is fine.'

I should have known better right then and there, but I proceeded to use the generator. After two days (approximately 10 hours of low load operation) my 26watt fluorescent drop lamp exploded behind my head. I immediately unplugged the lamp and went to the generator and tested the output at each of the outlets. They were both indicating 200 volts so I shut the unit down. I later discovered that three surge protectors with no connected load powered-up smoked and shorted out.

There is no power gauge on the unit and the circuit protectors are a tragic accident waiting to happen. For the few seconds this power surged it was surprising how much smoke filled the house.

I am experienced around this type of equipment and only heavy duty extension cords were used. Restarting the unit briefly I still measured 200 volts with my multimeter.

IN MY OPINION THIS UNIT IS UNSAFE AND I WOULD NOT OPERATE IT LET ALONE RECOMMEND IT TO ANYONE!

The generator is everything it was advertised to be. There is no problem with that part. The problem is the booklet that comes with the generator. It keeps the generator from getting 5 stars. It's obvious that it is poorly translated from another language. The booklet states to fill the oil reservoir with oil before starting. There is nothing telling me what type or weight oil to use. There is a service number to call but it is hard to get help. Otherwise this is a good product for emergent use. Overall, an excellent buy. You DO get your moneys worth.

I purchased this item back in dacember. I haven't used much but when I needed it, it would not work, very disapointed. (stored in a heated garage ) after I pull, it starts then shuts right off. 2 times it backfired on me and I am also having a problems with the pull chord where it doesn't catch the fly wheel so I pull and it doesn't allways turn it ... Not sure what I'm gonna do yet about it,

My Advice buy one from harbor freight or home depot

I ordered this generator on sale at Amazon. It came with free shipping. Well you get what you pay for. When I received it the bottom of the box was open and some of the paperwork was missing as well as the entire frame of the machine being bent out of shape. When I called buffalo tools about it the technician suggested beating it back into shape with a hammer. He was serious. Apparently this is a common problem because he told me where it was bent! When I indicated this might cause further damage I was told to take it to a local repair shop. Well I ordered it around thanksgiving and we are getting close to Christmas and its still in the shop. It has never even been started. This machine needs better packaging for starters. I will write another review when it actually is used.

Worst generator I have ever purchased. It has been a lemon the first day I received it. I was sent a second and it did run a little longer but also went out 4 times and they did send replacement parts. This is a clone of a clone. I have had Honda generators and the Chines clone of the Honda under the name of Champion which I like over the Honda and the price is much cheaper but the Sportsman is the worst I have ever had. Would never order another one. If I could give it a Zero Star I would.

This unit works ok for the price. There have been a few times when the heat may have caused a shut off. The plastic housing around the wiring harness was damaged, so took the unit apart and used black duck tape to repair. Other than that, ok for price.

great out of the box runs like a champ and handles a large load of power. instructions are easy to follow and starts up quickly. not having a wheel kit it is not that heavy and can be moved easily... I never had to keep moving a generator to use it so I would rather cut the cost and lift alittle
