Following posts on this site I have acquired the above. Spent a happy hour this afternoon assembling it. I have followed the instructions, with a little difficulty. Having used up all the screws and the washer I assume I have it right. However I have 4 items left over, none of which I can find reference to on the instructions and diagrams. 1)A question mark shaped item of thick wire (for cleaning the nozzle perhaps?) 2) An cylindrical hard plastic piece with a projection on the long side with a slot at the bottom. 3) Another hard plastic piece like a distorted U, again with a slot on the long side. 4) Another much larger hard plastic U, but more complex and number
40080785 stamped on the inside. Any help appreciated.
