besides what Don said, get some material you can practice cutting. You might be pushing the material to one side without realizing it, making the blade twist.

Like most power tools, getting it to cut is easy, being able cut exactly down the center of a pencil mark, without tearing up the material, takes lots and lots of practice.

while you are cutting experiment a little. Instead of turning the material more and more try pushing it a little to the left or right and see what happens

or try turning it the other way. Power tools dont always respond like you think they should. you gotta develop a feel for it.
