Material not being held firmly, causing the blade to twist or jam in the cut.
Hold the material firmly. If using masonry saw, clamp material or check the table wheels for excessive wear.
Blade is too hard for the material being cut.
Twisting or turning the saw while the blade is cutting causing the blade to jam.
Defective clamp plates which cause the blade to flutter in the cut.
Blade is cutting out of round, resulting in a pounding action.
Use the proper blade specification for the material being cut.
Follow safe operating practices or use blades with greater thickness.
Ensure flanges are clean, free from dirt and burrs.
Replace defective machine parts such as bearings or blade shaft.
