The blade guide side bearings support and twist the blade straight so the blade will enter the workpiece perpendicular to the table surface (see Figure )(). The blade guide support bearings prevent blade twist by stopping the blade from being pushed back during a cut. Both adjustments are critical for correct saw operation.
Note: Make sure the blade is tensioned and tracks correctly before you adjust the blade guide bearings. Refer to Blade Tension on the previous page and Blade Tracking on Page)0 for detailed instructions.
