The Boss 4111 (An Electrolux in drag)

This little fellow came by way of a cousin of mine, who had upgraded. It looks a nice little thing, it found it's way into the back of my car at a family party a month or so ago



It looks tidy. Only had one tool though

and a horrible re-useable cloth bag, with some tears in it as I later find out

I wondered what to do with it at first, until someone at work asked me if I had anything for a 1 bedroom flat with floorboards throughout and one rug. Perfect!

 So let's have it apart!
 The extension tubes have a stiff rubber bush in the end, which pops out very easily
 The parking bracket unscrews from the pole it sits on
Floortool now, and I do like the design of these. Simple but quite effective
 Cover off
 The pedal unclips from the mechanism
 The elbow unpops from the assembly
 and the 2 rubber squeegee's slide out of their holder
This random cover unclips from inside the floor tool
 the 2 rear wheels pop out easily
 And now onto the machine. The tool cover door unclips from it's 2 locating pegs

 poor lonely crevice tool!
Bag door now, which is held on with 2 more locating lugs

 The hose entry gubbins unscrews, and the 1 rubber seal pulls off
 The release clip for the bag door unclips

 The bag full indicator (which doesnt work very well) is held in with these 2 screws

 and comes apart like so
The horrible cloth bag comes out
 and the bag holder slides out of the lower chassis
 This orange part ensures the bag door cannot be closed without a bag fitted, and pulls out
 Post motor filter
 and the post motor filter

 Switch assembly now, which is a pain to get at, with 4 clips needing to be popped out
 to reveal this
 The speed control board unscrews and unplugs from underneath, and the slider pops out with a gentle prod
The pedals are held down with this bracket
 Once removed the pedals lift off
 The wiring to the speed control is held in place with a little rubber grommit
 The 3 Phillips and 1 security torx screw that hold the top cover down are removed
 and the switch unplugged
 The switch unscrews from above, and this small random plastic peg pops out of the top grille
 Switch out
 Identical to a Dyson switch!
 We can see the main bits now!
The motor lifts out
 and the rear mount lifts off

 The cord rewind mechanism holds the PCB
 Once unscrewed the 2 pink wires can be removed from the cord reel


 The back plate of the cord reel unscrews, and the brake mechanism can be removed. As long as the reel is reeled up, the plug will hold the tension in the mechanism. The contact reel between the cord reel and fixed plate lifts out at this point too


Now comes the hard part. The plug won't actually withdraw from the chassis, you either have to cut it off and fit a new plug, or remove the cord from the reel. If cutting the plug off, leave the back plate and brake mechanism on to stop the cord unreeling itself.

 I chose to remove the cord from the reel. The easiest way to do this is to NOT remove the cover on the spring

Which pings the spring everywhere and takes 2 hours to put right. CUT THE PLUG OFF! However, once you have doinged the spring everywhere, you can remove the 3 screws that hold the 2 parts of the reel together (this is probably possible with the bracket fitted, the reel will un-tension itself alarmingly fast though) and seperate the reel. You will then need to cut the wires from the reel contacts and re-solder them on. Great innit (this is why I said just keep the reel whole and lop the plug off...)

I'll come back to that. The top half of the front carry handle unscrews
 The front wheel unscrews
 and comes apart
 The bag chamber seal lifts out
 The hubcaps come off the rear wheels, but I can't see a way of removing the rear wheels easily, so left them alone.
 I dismantled the bag (didn't know it was torn at this stage), The bag holder unscrews with tiny little nuts and bolts
 But is sewn together in the middle for reasons I can't work out...
Done, she is apart! All the bits were washed, dried and polished, and then re-assembly commenced!
Starting with some soldering, I used a PC I pulled out of a skip as a solder station. IMPORTANT, MAKE SURE THE CABLE IS FED THE CORRECT WAY THROUGH THE CHASSIS PRIOR TO THIS STEP! I nearly got it very wrong...
 Refit a reel contact, solder the correct wire on, tuck the wire into the cord grips to hold it, and repeat on the other contact
 Make sure the cable is routed correctly and close the reel up and do the screws up
 Drop the contact plate into the main housing
 It only fits one way
 Re-fit the brake
 I cleaned the rubber wheel up which makes it grip much better
 Fit the brake and screw it up
 Ensure the guide roller is fitted
 Fit the wiring and PCB to the housing
 The easiest way to re-tension it I found was to manually wind the cord onto the reel, fit the reel, pull a foot or 2 of cord out, wind it manually back on and then check the operation. Fine tune it so the action is nice and sharp
 Once happy, fit the reel properly, and refit the motor
 Then the switch and top housing
 Then the very top housing, pedals, pedal holding bracket, speed control knob and PCB and snap that onto the top assembly
 Front wheel refitted
 Rear wheel hubcaps fitted
 Front handle cover fitted
 Bag door safety latch fitted with its spring
The filters washed up well and were refitted

 Bag door clip refitted
 Bag full indicator re-assembled and refitted, then the bag door can be fitted to the machine
 The floor tool and extension wands are reassembled
I found some tools in the shed that fit enough for the tool door to close (and their electrolux tools too, from a Lite/Chic
 Massive bonus was finding this pack of paper bags for it in the shed, which was excellent as the cloth bag was ruined, and I hate re-useable cloth bags anyway, messy to empty and they kill performance

 The hose was re-assembled
 Each end is held in place with removable clip rings

 And it is done!
A tidy little machine, which will go on to give years of service to my work colleague! (hopefully, I sit next to her so if it doesn't I'll know about it!)

Hope you enjoyed reading this!
