Even the tiniest of cracks in conduit can let saw dust impact inside conduit. Between that and the twisting stress point on your wires can cause machine failure or even short your system. Replace damaged conduit as soon as possible. We suggest 3/4" metallic liquid tight conduit.
We also offer a repair kit for XL-Saw blade motor power wires that includes a junction box for ease of replacement. See more about Part # CE-0014 here.
