Hi. I'm new here. Looking forward to interesting communications. What brought me here are the posts regarding my Smartpilot X5-R. Mine also has stuck and stiff to turn without auto on. I see one fella took his apart and greased the spring. I would to do that too, but how the heck do you take the cover off? I see a slot at the bottom and I tried with a flat head screw driver but it feels like there is something holding it together. Help?
