How to replace your shave head
For older models which have a foil and a cutter block as two independent parts, you will need to change the parts in two steps:
First remove the foil, either by pressing the release button if you shaver has one, or by pulling the foil.
Next rotate the cutter block by 90 degrees and pull it off, holding it at the ends to avoid touching the blades.
To fit new parts, simply carry out the same procedure in reverse.
