The blade on the Ryobi P550 may be binding due to one or more of the following reasons:

1. The workpiece is not held firmly against the fence, causing it to twist or slip during cutting.
2. A bevel cut is attempted through an auxiliary fence not designed for it.
3. The miter table is not clamped down, allowing it to move during the cut.
4. The blade teeth are not pointing downward at the front of the saw as required.
5. The blade bolt or washers are not properly installed, causing improper tightening.

Each of these can lead to the blade grabbing or binding in the workpiece, which may cause motor stalling or kickback.
