Cannot read or understand your instructions, appear to be written by engineers for engineers not non-expert end users. Unable to understand, identify or fit any of the lumps of metal in the polythene bags but have worked out how to free blade and actually use the machine. Have ended up with cut wood which is what I bought it for. Good. Have fitted the dust bag which remains empty and floor surrounding machine and all surfaces of machine are covered in sawdust. Not impressed. Perhaps I should have purchased a simpler less advanced and less expensive saw I am never going to be able to understand all the functions that might be able available if I could only understand them. Pity
