Lots of cautions (7 pages) but no assembly instructions. Two pages for the schematic but again no assembly. I don't know what 2 small springs, 1 medium spring, 4 foam discs and 4 small metal discs are for. The extension cord was difficult to fit into the handle. I had to smear. Attaching the handle to the engine wasn't easy. I installed it backwards until I posted the picture on Amazon. Not sure if the curved skirt that helps collect dust can be removed. I'll try anyway and hope for the best.
