How to replace the wiper rear arm?

[abels]

Can anyone tell me how can I replace the wiper rear arm from Altea XL, please? After I remove washer cap cover I don't know what do next. Have to pull? Or unscrew anything? Thank you.

Loosen hexagonal bolt, but do not remove completely. Then use a wiper extractor tool and apply it to proper position. Raise the wiper arm and separate from cone using lateral movements with the help of the extractor tool. Then unscrew hexagonal bolt completely and remove wiper arm.

What do you mean by "a wiper extractor tool"?
