Operation Tips for More Accurate Cuts
• Allow the wheel to do the cutting. Excessive force will cause
the wheel to glaze reducing cutting efficiency and/or to deflect
causing inaccurate cuts.
• Properly adjust fence angle.
• Make sure material is laying flat across base.
• Properly clamp material to avoid movement and vibration.
