my first casting rod

[ryno5217]

and i cant figure out how to use it.....Its a bill dance, not sure on the model, cheap rod and every time i cast the line i get the birds nest or whatever its called where the lines spools loose all over the reel (spindle?). There's a small gold knob under the handle and a button that turns on the other side, numbered one thru ten, neither of which seems to effect the drag. hopefully this is enough for someone to help me out, sorry i dont know my terminology and equipment better...any tips appreciated
