Congrats on your machine! If you can find silicone oil spray or even Teflon spray oil, hit the bearings that ride on the track (tension rail). WD-40 works in a pinch, but does not last as long. As for a cover, TM has them for $25, but shipping is $14 and up. You might want to add a dog kit ($15), for when the mounts start slipping. I had to wait 4 months to get my order.
