What is the issue?: The rear guard may break or detach and make contact with the saw blade. If the rear guard contacts the saw blade, fragments may be thrown from a rotating blade contacting the operator or bystander and causing injury.

What to do: Stop using the mitre saw, check the model, type number and date code against the details above.  If your product is impacted, contact the DEWALT Customer Service team to receive a free repair kit.
