Object cannot rotate above 360 degrees

Hi !

I’m currently creating an horror game where the player have to run because spinning windmills are just behind him.
Unfortunately in Matinee I can translate the blade but I cant rotate it more than 360 degrees.
After searching on internet I met someone having the same problem as me : https://answers.unrealengine.com/questions/293439/matinee-wheel-spin-animation.html

The answer of the man was “Use a Timeline to animate wheel rotation in Level BP, then play this timeline with an Event Key in Matinee at any frame of the animation sequence.”
But when I done my timeline I don’t know at what I should link it to in order to make the blade rotate.

Can you help me please ? Thanks in advance !
