Notes

This is a high-volume jobsite table saw used by contractors for ripping sheet goods and framing stock. A common "repair" decision is getting the rack-and-pinion fence aligned and the rails square, because accuracy depends on fence parallelism and smooth travel.

Fence issues are often fixable with adjustment, cleaning, or replacing worn gears/knobs-usually well under the threshold. Deeper repairs (arbor bearings, height/tilt gear damage, switch failures) can add up, especially if the saw has seen dust-heavy work without cleaning.

Repair is favored when the motor is strong and the table/stand are straight. Replace if the saw can't hold alignment, the arbor shows runout, or multiple drive components are worn, since precision and safety suffer.
