Notes

This is a premium, accuracy-focused miter saw commonly used in finish carpentry where clean cuts and dust control matter. "Motor tripping under load" can be caused by worn brushes, an overtaxed circuit, a failing switch, or an electronics fault in soft-start/overload systems.

Because the replacement price is high, repair is often the rational path if the problem can be traced to a single component and the saw's mechanical accuracy (rails, detents, fence) remains excellent. Replacement becomes more compelling if the saw has multiple symptoms (tripping plus inconsistent speed, repeated electronic faults, or significant rail play) because high-end repairs can stack quickly.

Also factor in downtime: for pros, a dependable backup tool can change the economics. Pricing reference: Highland Woodworking Festool Kapex KS 120 listing.
