I use mine just fine with zigzagging and other fancy stitches. My feeddog doesn't work right now, so I'm using the walking foot all the time. Just finished with a buttonhole stitch to applique some fan blades onto the background fabric and it worked great.
Best to check your instructions, but if you have a wide throat (place for the needle to go down), you should be able to zig zag as well. You won't break it, but the needle will break if you don't.
