Start with the model number
Read the model from the saw’s identification plate, not just the wheel diameter or the name printed on its cover. Keep suffixes such as T, Z, B or P2: kits and tool-only versions remain separate records. An older model number is not automatically an alias for a newer saw.
Check the specification in the manual
- Find “Blade length,” “Blade size” or the specification table in the correct model’s manual.
- Record the required length and the supported width range. Also check blade thickness, guide restrictions and any riser-block configuration.
- If the manual gives a length range, preserve both endpoints. Do not assume that the minimum is the nominal replacement size.
Use the installed blade as a cross-check
A legible blade marking or part number can help identify a replacement. An installed blade may be an incorrect or modified fit, so it should not override the manufacturer’s specification.
Use the Finder to locate the recorded model and open its manufacturer sources. If a field is marked “Not verified,” check the manual directly before buying.
For model-specific requirements, use the Finder and follow the manufacturer documents linked on the model page.
