I used to own this, and now I don't, having swapped it recently for something amazing! But I have a stripdown and almost refurb thread of stuff for it, so why not write it up!
I owned it for a fair few years actually, I bought it on ebay cheaply from the notorious vacuum destroyer joshyvacboy.
It worked OK. Here is Eva, probably not 2 at the time playing with it in 2013

Anyway, here it is cleaning our old flat the day we moved out!
//www.youtube.com/watch?v=WRNAsROXr-o
It was the last vacuum to clean there, and the first to clean our current house! (as it was the only vac I had to hand the day we moved in!)
I used it as my January Vac!
//www.youtube.com/watch?v=LUH_fCw1ReQ
Which involved cleaning up after taking the christmas tree down
And it was generally pretty great. So let's get on with the usual style refurbishment, although it did not go entirely to plan!
Let's begin *cracks open a can*
April 1983!
The wands are not original sadly, but do their job well bar not being brown
The floor tool is apparently very rare, being a long neck brown one!

Underneath was worn but not too bad
(I cleaned this out a few years ago so it's not too bad now) but baseplate off
And their springs
The brush plate lifts out
And the brushes pop out for a thorough clean
The pedal assembly pops out
And then the neck
Onto the hose now, and again not original, although the machine originally came to me with a strech hose, also wrong but horrible to use, so I picked this up from another collector years ago.
The Contour handle unscrews

The suction control slider sits in this half
And pulls out
The Pip lock lever lifts out of the front part
I could not get the ends off the hose at all, they would not budge, which made cleaning it alot harder than it should have been, but more on that later!
Because it's time for the main show!
Bag door off
Tool tray out. Sadly 2 of the tools are non original
The dusting brush has seen some use
Crevice tool isnt too bad

However the upholstery brush is lovely and original
Tool tray is lovely and unbroken too
Under the tool tray sits the bag. The chamber is sealed by the tool tray, so you can take the lid off to get at tools with the machine running.
Good old single walled paper bags...
The pre motor filter was dirty, but not too bad
That removed, it's time to get electrical!
This cover is broken sadly, it was when I got it. All the original sound deadening had long gone too
The lid is wired up to the motor with 2 plugs

and one here
That separates the lid
The brown trim is removed with screws and clips (some broken)
The spring sits under the power button end
A previous repair (not by me, but it makes it much more tricky to try when someone else has been there before...
The spring sits here like so
The big rocker switch just lifts out
Revealing the switch arrangements. The E lever is depressed automatically with the machine switched on (it pushes the switch). The white switch controls the oepration though, so each button just flicks the switch one way. The main power switch is the black one to the side
Wires to the power switch
Switch removed

The mode adjustment switch looks like this underneath
Unplugged
And removed
The LED panel lifts out of the holder
The coloured lenses lift off the trim
How far have speed adjustment potentiometers come!
The lights lift out of the housing
And the adjuster module unclips too

The adjuster wheel pulls off the electronics
Branding
More on these hateful things later!
The selector arms come apart
Onwards!
The Pre motor filter cover unscrews

This part here forms part of the blockage notification! It's a magnet within an arm, that gets pulled up (or down, I can't remember...) when the suction is blocked.
Now, we need to turn everything on it's head
And remove all the screws
2 hide behind the rear wheels
Then the outer shell lifts off
The mahoosive side bumpers lift off
Which are a bit grubby
Turns out the bumpers are in 2 parts too, so apart they come!

Where were we? Oh yes!
Underneath the machine, now visible with the shell off is a tab that holds the cord reel in
But we don't want that for now, we need to snip some cable ties!
And lift the dividing wall out
Then remove the plug (as it would have come without one, and the plug doesnt fit through the cable exit hole!)
Now we can lift the cord reel out, the beige firewall holds it down. Then, open up the box holding 4 live wires, the front right one goes to the cord reel, remove it
The red wire however goes to one of the multiblocks, and the easiest way to remove that was to unplug the single brown connector
Remove the supressor
Then finally remove the red wire from this block, noting where it goes

Finally, we can call the cord reel removed!
And look at the rest of the rats nest
This connector is factory, I initially thought it wasn't but can see no reason why it would have been added...
But, to aid the rats nest at the back, we need to move down to the front
And remove the hose inlet
Then unscrew the power nozzle plug
The power nozzle wires can then be pulled up and out of the machine like so
The motor just sits in the chassis, and would pull right out bar a short earth wire that took some creativity to remove
It's 2 live wires are unplugged, one goes to the block of 4 and the other to the one lone brown connector

The main loom of wires runs to behind here
Behind here houses the PCB that runs the show
Down under the motor sits a thermal cutout
And the machine is de-wired! Note the removed part of the chassis, more on that in a sec. But first, some ancient crumbly diffuser fell out
And I removed the bit that housed the TCO before I forgot where it went/it fell off
The reason I had to remove the main firewall was the bag full mechanism, which is here
It's actually quite cool, it's a magnetic switch. When the lack of airflow causes the sprung magnet the other side of the plastic to move, it pulls the contacts together and thrown the bag full light on! Sellotape removed and out it comes
Info on the PCB
And it is all finally out of the machine!

Whilst we are there, the motor fancase rubber can come off
As can the cord reel locking device, which pops out of here
The cable guide is clipped onto this the other side
And the spring sits like so
The little rubber pad slides off
Back to the front again, we can remove the hose lock from the hose entry part
The release knob lifts out with the black part removed (The black part lifts the release knob as the hose is inserted)
The rear grille slides out of the chassis

The bag holder has a plastic bush that widens it out slightly to fit though the chassis and create an air tight seal to the hose inlet side
This yellow arm holds the bag in place, and fits like so
This rubber seal sits between the white bush and the green part
The seal on the bag side was done for, so I removed the remains
The carry handle is another insert and lifts out
Underneath is a front wheel!
Once unscrewed, you can see 2 white nylon rollers underneath
And the main wheel pops out
The chassis is empty! Years of carbon dust are now visible after I've got my fingerprints all over it

The motor has 2 soundproofing (I presume) shells around it that unscrew
And 2 anti vibration posts that hold the shells on
to reveal the motor itself
These french motors HATE being disassembled, so I am doing nothing to it!
It's utterly fine anyway, little drop of oil on the top bearing will see it reet
The cord rewind had to be cable tied as it very slowly unwound itself...
And we are stripped!
Everything was washed and polished in the usual way
And I tried to make sense of the wiring...
There's a loom for the controls on the lid, then the main chassis loom. I untangled it all

I then gave it a light polish
Which came up well
Caught my bloody pad on an edge though, luckily they are very cheap
This put some shine back into the plastic
