Hi everyone. I have an Ozito 210mm dual bevel sliding mitre saw. While cutting up aome wood, a small piece flung off and got stuck in the blade guard. After I removed that piece, the blade guard doesn't go up as far up anymore as it used to when I bring the handle down to make a cut. Below is the pic that shows the blade guard when the saw is at its lowest point.

What can be done to make it right again?
