Indicate rotational limitations of shaft, on Drawing

Hello,

First time poster here.

I am currently making drawings, on a specific positions of a robot arm.

In this i need to indicate a specific rotation of a shaft, but i am not able to do that.

I have attached a picture, that indicates what i need.

If someone culd explain to me, how that is done, it would be much appriciated.
