Notice the tension wheel located just inside the bar. Use a flat-head screwdriver to turn the screw to the left and release some tension. Pull the chain away from the grooves of the bar. Ensure that all of the grooves are removed all the way down the bar until the chain is free.

Now pull off the bar or blade and check to see if repairs or replacements are needed before replacing the chain. Some simple repairs can then be made, such as bending a bent bar back into place or sharpening the teeth that run along the blade. If teeth are missing, then a replacement is needed. You may need to buy a new bar.
