Thank you but this is not like my Fuji tap (which was purchased 4 years ago and must be a previous version). The moveable part of the tap appears to be secured by a flange with no visible fixing such as a grub-screw or any moulding to enable it to be unscrewed (if indeed that is what is needed). There is a grub-screw in the side of the lever shaft that probably secures it to the cartridge, but removal of it only allows the shaft to slide inside the flange which remains firmly attached to the body of the tap. When I consulted the cartridge supplier (Central Services) I was advised that removal of the grub-screw in the shaft would allow everything to be withdrawn, exposing the cartridge. P.S. I can see from the exploded drawing you supplied that the later version is constructed in the same way as those with the cartridge in a vertical position. I only wish mine were!
No, it is trapped by the flange. My tap does not have a moulded lever like that in the picture. It is a hollow rod projecting from a hemisphere (trapped by the flange) into which another solid rod handle is screwed at right-angles. I think I have the model no. here which should enable you to trace the correct instructions. It is(NNN) NNN-NNNN988. It was ordered on-line from Franke on 29/11/10. Unfortunately no instruction sheet was provided.
Thank you for your response. No, the cover does not turn as part of the tap operation. It is rock solid. I am afraid you are probably right that it needs to be pulled or levered off. This was my first conclusion but unfortunately I can see no way of applying either leverage or pull to it without causing damage. No wonder Franke changed the design! Following a 'suggestion' on You-tube I am currently attempting to introduce vinegar into the join in the hope of freeing it.
Thanks again. Have tried the grips and got a good purchase using a kitchen rubber cap-gripper. Applied as much force as I dared with my wife applying a balancing force to the spout but it won't move. Have decided to change the tap.
Thanks very much, very helpful I will take it up with Franke.
