hi,
on no account try to remove the nozzle when it is cold, you will shear it off.
set the printer to withdraw or extrude and once the nozzle is up to tempersture (260 degrees), you should be able to remove the nozzle with the tool provided.
Refit the nozzle cold, do not tighten it further when hot.

once you have done this younwill need to do a new nozzle height calibration as, in my opinion, the nozzle never sits at exactly the same height after removal and refit.
cheers

Peter
