1984 300TD Wagon Manual Sunroof Operation?

[aaronkobi]

Since I don't have an owners manual, I was wondering if somebody could describe the operation of the manual sunroof... I tried to open it once and it was sticky, so I didn't want to force anything. I realize that you pull the handle down, then turn to disengage. From there, should the window just slide back into the roof? How far back does it go? If it doesn't slide smoothly, is it just a matter of greasing the rails with mercedes sunroof grease?

Glad that I have a manual roof as opposed to electric... those sound like a nightmare to repair!

Thanks!
