Lidl document shredder UAV 190 B2 - putting it back together!

The on/off switch is the same idea  on mine, just the other way round, centre off, left reverse, right normal.
Don't understand what you mean by 'the cutting wheels in a bank'..........?
Have to say, you are being very helpful, for which I am very grateful!

All the cutting wheels/discs are mounted on something so they can be lifted in/out of the unit.  Is it possible when you reassembled the unit that you rotated the wheels by 180 degrees, either by turning them upside down or left to right?

weezie7

Understand about the wheels/discs, they are mounted, just fitted them back into place. I did wonder if I had put it back wrong, but am pretty sure I didn't, as the motor is on the right, and I made sure when I looked at it originally that it was on the same place. It is almost like something is stopping the forward movement, as the reverse works!! I will have another look at it, but I don't think it fits in the other way!

OK, that is new information, I read your earlier post as meaning it only worked in reverse when you placed a piece of paper in and it triggered the micro switch.  What you are saying is that it doesn't run at all in forward but will work in reverse when switched to reverse.  When it is switched to forward and you slip a piece of paper in, does it even try to move, can you hear the motor straining, does it immediately go into reverse mode?

I reckon that a proper, decently lit photo of the whole inside would help. From a couple of angles if possible, as well as from directly over the cutters. When I say "decent lighting" just even light out of direct sunlight, with no strong shadows. 
As Le_Kirk said, does it try to run or not run at all?
If it's the latter then it's probably either the microswitch arm / assembly isn't right, or there is a displaced or misplaced connection.
If it tries to run, then it could be the cutters, or gears are assembled incorrectly.
TBH, you have to look at the thing, determine how it's supposed to work, and then re-assemble it to do so. The majority of parts will probably only fit in one way, but there's always the bit that will fool you!
No offence, but it all goes to show why the advice to never take things apart "to see why they are working so well" is worth following!

But that would blow out my philosophy of "if it ain't broke, break it and then fix it."

Let's admit it, that's how most of us learned to fix stuff
"How does this work?"
Having a long, (and in some cases damned expensive!) history of breaking stuff to make it better, I try not to pull stuff apart these days.

Yep. Learned my lesson. I leave it to the internet and people like Big Clive to pull things apart now.

Yes, I watch his videos occasionally. Very knowledgeable he is. Funny on occasion as well.
You're right though, watching them does quieten the craving to pull things apart.
There's a good reason for me having the guts out of this 3D printer. 
Really!

Okay guys. I understand about not breaking things, but I wasn't trying to, I just wanted to clean it a bit!! I was very careful taking it apart, until I turned it upside down, that is when it all fell out!!
I have a bit more info! Yes the shredder wheels/cutting blades do turn when the power is on and it is switched to reverse. No they do not work on forward/normal/auto. (I did actually take whole thing apart and plugged in (yes, I know H&S etc..... but was really careful) so could see blades turning when in reverse mode. 
The blades/wheels are in the right way up, as I cleaned it with a small brush, and when I turned them over to check, could see loads of dust, where had not been cleaned, so definitely the right way up.
When the shredder is switched to auto/forward, there is no noise at all, no motor, no blades trying to turn, nothing. I have tried with putting a piece of paper in it too, as I think normally it will only turn when paper is inserted in the blades, it obviously has some sort of 'sensor' to sense the paper going in.
Also, have put a photo of what I think may be the offending 'bit', the little black thing with two red wires, and the little white bit, which pushes in..... 
It looks like it is in the right place, as it has two small holes in it, so it can fit on two 'spikes' underneath it.
