  • Page 29: Disabling Switch

    Always use relief cuts when possible. • Misusing the saw or using incorrect tech- niques (e.g. twisting the blade with the workpiece, incorrect feed rate, etc.) is unsafe and results in poor cuts. -27- G0803 (Mfd. Since 09/15)

  • Page 32: Tooth Pitch

    Hook: The teeth have a positive angle (down- ward) which makes them dig into the material, and the gullets are usually rounded for easier waste removal. These blades are excellent for the tough demands of resawing and rip- ping thick material. -30- G0803 (Mfd. Since 09/15)

  • Page 35: Resawing

    When resawing thin pieces, a wandering blade (blade lead) can tear through the side of the workpiece, exposing your hands to the blade teeth. Always use push blocks when resawing and keep your hands clear of the blade. -33- G0803 (Mfd. Since 09/15)
