Nilfisk king 540: The cable is stuck. I can´t take it out
Tools required: Haxalobular screwdriver (Torx or 'Star'), Strong hands/fingers, flathead screwdriver.
Possible hazards: sharp edges (metal plastic), bacteria enriched dust/dirt.
Notice the black ring/skirt near the bottom of the unit...sit on the vacuum cleaner, and pull very firmly at the ring, which will begin to click and pull upwards, rotate around the unit pulling the ring up until the whole ring comes off and you can pull it off over the top of the unit.
Now, there will be a white plastic ring revealed around the unit, using a Flat Head screwdriver to pry the ring out of the grooves it sits in (pull it off towards the bottom of the unit as opposed to the intial black ring coming off upwards).
Now take the handle of the unit and give a firm **** upwards, the whole encasement will slide off in your hand.
You will now see the spring loaded cord retracter. The problem here is that the spring has become too losely wound back onto the larger spindle, or it is dirty.
Firstly pull the entire power cord through the outer shell that you removed (you will need to unscrew and remove the black facade that the cord goes through otherwise the head of the cord wont go through).
Then take the plastic cirlce cover off the smaller spindle (carefully as the wound tin spring could pounce).
Now you need to manually turn the larger wheel clockwise until it has no coil left on it, and the smaller coil now is full.
While winding, dont let the powercord wind back onto the wheel, let it sit to the side (there will be a bit of tangle which will go back to normal when we finish winding back the other way).
Once it is fully loaded onto the smaller coil, wind it back on to the larger coil again, but make sure it's loading on 'tight'. You can ensure this by keeping some pressure on the smaller spindle while winding (be carefull because the coil edge is sharp). Once the smaller coil is basically gone and there is just a small curved end of the coil, put the small spindle back on making the curved coil wrap around it.
Wind some coil back onto the smaller spindle so there is atleast one full ring plus a small overlap, around the spindle, or it may come off. Also, make sure that where the cord is coming out of the larger spindle, is pointing towards where it goes out the back of the vacuum cleaner, so that when you pull the cable it wont wind the wheel at all, otherwise it may wind some coil off the smaller spindle.
Proceed to put the unit back together, but before putting the white and black rings back on, test the retract button. I noticed the first attempt to put it back together that the external button had not lined up with the internal mechanism and it wouldnt retract, i had to open it again.
All done, it should now retract, but it will never be as strong as the day you bought it, but atleast you dont have to have the cord hanging round. Hope this helps.
