300cd seat adjustment?
 

Hello everyone,
I have recently bought a 79 300cd. I am still getting familiar with this nice machine. I have a few basic problem. How do I adjust the seat height. The lever on the side is very stubburn and it doesn't seem to make the seat go up or down. Also do the headrest suppose to move forward to better accomodate my head? It looks like it can be adjusted. I have the owners manual but it is not doing me any justice. Thanks to everyone.

The seat lever on the side does control movement up and down, but only as part of additional movement forward and back (if you pull up on lever (gently, they are usually quite brittle with age) and slide seat forward it will also move upward slightly). The same is true in moving backward except it will go down. I believe that every few inches of travel forward or back equals approximately an inch up or down.

Hope this helps
