Parts: none.
Do:
- Measure both plan diagonals of the bottom square, outside face to outside face.
- Tap the longer diagonal's corner inward with the mallet until the pair agrees.
- Tighten the 8 bottom joints fully, diagonal pattern, then re-measure.
Check
Both diagonals equal, near 721 mm on a 350, and all four corners 90°. Record the pair in the log. src
Helper Holds the tape's far end on the corner and reads each diagonal aloud.
What you're looking at
Manual p.21 shows the squareness check, measuring both plan diagonals of the bottom square. A rectangle whose two diagonals are equal is square. The absolute number does not matter, only that the pair agree, so hook the tape the same way both times.
