Check the calibration:
- Confirm that the outfeed table is parallel to the cutter head.
- Confirm that the outfeed table is level with the top dead center of the cut.
- Then confirm that the infeed table is parallel to the outfeed
- Lastly confirm that the fence, when set to 90, is square to the outfeed table.
This should all the the case right out off the pallet but it's worth a check.
