Table Saw: Bad angle cuts
If angle-cut work pieces don't fit together, you may need to adjust blade alignment, the bevel positive stops or the bevel pointer. If the angle cuts have ragged, torn, splintered or burnt edges, you may need to replace the saw blade.
The blade must be parallel to the miter gauge groove to achieve clean angle cuts. Check blade alignment using a combination square and adjust the blade to parallel with the miter gauge groove if blade alignment is off.
Next, check the 90-degree and 45-degree bevel positive stops and adjust those stops if necessary so blade angle is accurate.
Check the accuracy of the bevel pointer and adjust the pointer to accurate indicate blade angle.
The saw blade must be clean and sharp to make clean angle cuts. Check the condition of the saw blade for damage or residue. Clean gum or pitch residue off the blade using turpentine and steel wool. Replace the blade if it's worn or damaged.
Adjust the table saw blade
The table saw blade won't make perfect cuts if it's not parallel with the miter gauge groove. Check the blade alignment using a combination square and adjust the blade to parallel with the miter gauge groove.
Adjust the table saw positive stops
The table saw has positive stops that quickly position the saw blade at 90-degree and 45-degree angles to the table. Use a combination square to check and adjust the angle stops for accurate cuts.
Replace the table saw blade
The table saw blade becomes dull with use. Cutting hard wood or metal dulls the blade faster. The blade is dull when you must apply significantly more than normal force to push the piece you're cutting through the blade.
Worn motor brushes can make the table saw motor run weak. Here’s how to replace them.
If the table saw isn’t cutting parallel to the miter gauge groove, adjust the cutting blade following the instructions in this repair guide.
