Troubleshooting

Blade feels loose after tightening the arbor nut

Verify the reducing bush is fully seated against the back flange and check that the outer washer is correctly aligned.

Bush is difficult to slide onto the arbor

Check the arbor for burrs or debris. If the arbor is clean, ensure the bush is not slightly bent.

Pros and Cons

Pros

  • Ensures a perfectly centered blade on the arbor
  • High-quality construction suitable for power tool applications
  • Essential for universal compatibility between mixed saw brands
  • Compact and lightweight design

Cons

  • Requires precise measurement of arbor and blade bore
  • Must be handled carefully to prevent loss, as it is supplied loose
  • Not a universal fit; only for specific 28.6mm to 30mm conversions

Setup, Compatibility & Care

Before installation, ensure the saw is disconnected from its power source. Clean the arbor surface and the blade bore of any sawdust or debris to ensure a flush fit. Slide the reducing bush onto the arbor; it should fit snugly without requiring excessive force. Once installed, verify there is no "play" in the blade by attempting to move it laterally. To maintain the bush, keep it free of rust and store it in a dry environment when not in use. Avoid using damaged or deformed bushes, as even a minor irregularity can cause the blade to wobble at high RPMs.
