The Leigh B975 manual insists I verify that the bit is not touching the E10 bushing when the bit is rotated: It never says what to do when it does touch. Explicit question: What do I do?

If the bit on the Leigh B975 touches the e10 bushing when rotated, check that the bit and collet are properly installed and secured. Ensure that the guide bushing retaining nut is correctly tightened under the router base. If the issue persists, verify that you are using the correct bit and collet size for the e10 bushing. Adjustments may be needed to ensure proper alignment and clearance.
