How should you position the cutting blade when cutting a finished floor to avoid damaging the finished side?

Positioning the cutting blade away from the finished side is essential to prevent any damage to the surface that may have undergone refinishing or installation. When the blade is directed away, it allows for a cleaner cut on the substrate without risking scratches, chips, or blemishes that could mar the aesthetic of the finished flooring. This technique ensures that any potential debris or material removed during the cutting process does not come into contact with the finished surface, thus maintaining its integrity and appearance.

The other positioning methods would bring the cutting blade closer to the finished edge, increasing the risk of damaging the surface. Therefore, directing the blade away represents the best practice for protecting the floor's finish.
