Waring Commercial Blade Series BB300 Blender, 48 oz, Black Read Description

I was able to power this on and turn the blender on. Both speeds work. The pulse also works. The blade appears to be a little loose and causes a loud noise to happen when it’s rotating. I’m unsure if this is how it is supposed to be. The blade is very tightly screwed in, however, does not appear to affect performance. If anything it may need a washer? Can’t be sure. Selling as is.
