You know looking at this again real good this is a very copy of the skil saw I had or skil copied this one, it did ok lasted about 6 projects then looked and ran like I had it 20 years. The so called bearings or bushings in the upper arm got loose allow side to side wiggle in the upper arm, blade had side to side back to front and kinda of better way to explain it, a sw to ne movement as well pending on how the blade was mounted. I took it back got a craftsman saw for the same price and it was alot better. Just be sure to oil the arm bearing(bushings) good like it says if it does before starting with it.
