  4. Press the Start (green) button to power the equipment on and confirm proper operation before using.

    • Ensure foot petal activates the shear.

Operation

  1. When ready, place the appropriate material on the shear’s surface.

    • If the material size is too long for the shear’s surface, use a roller-stand or request additional assistance from a coworker in the maintenance department to hold the excess material.

  2. Confirm material is appropriately situated. Place fingers are away from the blade and ensure in-front of the the cutting guard.

    • Never place fingers or other body parts between the blade and the shear’s surface. When servicing the equipment, make sure the blade has been locked and that all other energy types have been de-energized.

  3. Press the foot petal to operate the shear.

  4. Repeat as necessary.

Shutdown

  1. Press the Stop (red) button to power the equipment on.

  2. Confirm the equipment and work area is clear of debris.
