Great features

I Purchased a unit just like this one 28 years ago. It served me well over the years, I loaned to my children on several occasions. It finally started giving me a few problems so I give it to a friend. Being very pleased with the previous unit, I purchased this one expecting the same service

It is a nice one!

The unit is flawless after I secured two of the engine mounting bolts. Two of the four were not tightened at the factory. The nut fell off of one of them, luckily I discovered it almost immediately upon initial startup when I saw the nut laying on my sidewalk. I secured the two that were loose and checked all other fasteners and found that the rest were all fine. I have used the unit twice for a total of approximately 2 hours and it works flawlessly. I purchased the Simpson stainless surface washer unit as well and it made quick work of my patio and driveway. It is a nice one!
