On my 33", when i squeeze the blade engagement cable, sometimes [not always] it does not engage. To engage it i then pull on the cable with my thumb, then it engages and [fortunately] seems to then stay engaged. I was looking for a way to tighten the cable but don't see one. i thought it might be like a bike with a junction that you could tighten to tighten the cable. Is there a way to tighten the cable? What can be done about this? Need to buy a new cable? Thanks!
