The bushing gap is too wide.

The blade speed is too low.

Change bushing design to make them more supportive.

The bushing gap should be no more than .001-.003 inch larg- er than the blade. Check and adjust if necessary.

Low blade speeds can cause excessive blade interruption. Increase blade speed or decrease the blade cut path area.
