Hello has anyone had this problem i turn the crank handle to go down and it just clicks i turn it to go up its alright it just clicks going down but head wont move. so i opened the bottom and followed the instructions i thought maybe the head needs adjusting so following the instructions it says to check the tierod that connects the lead screws it is suppose to have a little play in it mine has no play and is real tight as far as trying to go side to side. So i'm stuck now and don't want to make things worse so i don't want to try anything else until i get help. i did email support but i just thought i would see if this problem is out there anywhere.

Thanks for the help
