This will walk you through it.
But yeah just like J madd said, when you push on the actuator arm (push it towards the clutch side) with your hand, with out the cable attached, it should stop at the arrow. So with the cable adjusted properly and cable attached to the arm it should line up at the arrow on the case with a little free play at the perch. A lot of people including myself like the arm to be just a tad behind the arrow on the case (toward the stator side)
