Inspect the blade if you are not satisfied with the quality of the cut. Make sure the blade is not dirty or turned off. If so, clean the blade, have it sharpened or replaced. If the blade needs replacement, make sure you do it with the correct type. Compare a new one with the existing sheet. Different blades are appropriate for different cuts, make sure you are using the right blade for the cut you need. Check the different types of sheets at your hardware store and compare features.
Check that the blade is not mounted upside down. If so, set it up and try again.
