Modern Vespa

Hello my mp3 yourban 2014 comes to 5k km and in the manual I see need to check Roll lock griper control cable.Any help for what I must check and where.
Ps sorry for my English

I found it, but what means to adjust.I think in off position cable need to be stretched or…

I stretched mine about 8-9mm, now it grabs faster when pushing the lock button. But... on my bike nothing had been done the last 8 years, or 10.000 km...

Could you perhaps show/explain how you did it?

Sorry, my bad, I assumed you knew...

After removing the windshield and the black cover under, the roll lock is visible. The black cable that goes to it can be stretched by unscrewing the adjustment bolt at its end, on the roll lock, 10mm I think... or was it 8mm?
Stretching the black cable is like shortening the wire inside it, just like the brake cable on a bicycle...

Have the bike standing without the lock engaged otherwise the wire will be stretched by the motor and impossible to adjust. And obviously , NO fingers in the vicinity if you choose to play with the mechanism back and fourth...

Hope my explanation made sense, this is taken from my mp3 400 but should be the same procedure on an yourban...
Otherwise post a picture and I'll try to do better.

Edit: ah,ok, thought it was Swimsas replying.

Thanks I think everything is clear.When remove the front cover I will check the cable if is loose will fix it
