As Alleyoop1 suggests, the manual is the best place to check where and how often to oil. I had no idea where to put the oil until I checked the manual. It has a good illustration of exactly were you need to place the oil.
Mitch's mom gives a good description of where to clean the dust. I dust more often if I am using a thread that is particularly linty.
In addition, the 2010 has a trap door in the bottom of the case. I turn the machine on its side. I open it and dust everywhere I can see. I use small artist's paint brushes. I like this feature as it allows me to really gather up all the "dust bunnies" that drop to the bottom.
Enjoy your machine. It is very solid and has a really nice stitch. I find I use the Juki most often for piecing and machine quilting and use my Bernina 630 for embroidery. Have fun!
