Notes

Sliding miter saws are precision cutting tools where alignment and smooth slides matter as much as motor power. Repairs are worthwhile for switches, brushes, and alignment components if the saw's rails and base are in good shape.

Replace if the slide mechanism is worn/loose, the arbor/bearings are damaged, or repeated alignment drift makes accurate cuts impossible. Dust collection and periodic cleaning help preserve rails and detents.
