Using the DeWalt DWS5100 Rip Guide is easy. First, set it up according to your desired rip width using the laser - etched markings. Make sure to secure it properly with the included screws. When making cuts, keep your hands at a safe distance from the blade. Always check that the guide is firmly in place before starting. For maintenance, wipe it down after each use to remove sawdust and debris. Store it in a dry place to prevent rusting. If you notice any damage, stop using it immediately and have it inspected or repaired.
