5. Operating Instructions

Follow these steps to sharpen your knives effectively:

General Sharpening Guidelines:

• Always start with a clean knife blade.
• Turn the sharpener ON using the power switch. The indicator light will illuminate.
• Hold the knife firmly by the handle.
• Insert the knife blade into the appropriate sharpening slot, ensuring the blade is centered and resting against the angle guide.
• Pull the knife slowly and steadily through the slot, from the heel to the tip of the blade. Maintain light, consistent downward pressure.
• Repeat the process, alternating between the left and right sides of the slot for an even edge.
• The number of passes depends on the dullness of the knife. For very dull knives, more passes may be required in the coarse stage.
• After sharpening, always wipe the blade clean with a damp cloth to remove any metal particles.

Step-by-Step Sharpening Process:

1. For Very Dull or Damaged Knives (Initial Sharpening):
   Use Stage 1 (Coarse). Make 5-10 slow passes through the left slot, then 5-10 slow passes through the right slot, alternating sides. Apply moderate downward pressure.
2. For Moderately Dull Knives or Daily Maintenance:
   Use Stage 2 (Fine). Make 3-5 slow passes through the left slot, then 3-5 slow passes through the right slot, alternating sides. Apply light downward pressure.
3. For Polishing and Finishing the Edge:
   Use Stage 3 (Polish). Make 1-2 very light passes through the left slot, then 1-2 very light passes through the right slot, alternating sides. This stage refines the edge and provides a polished finish.

Important: Always pull the knife towards you. Never push the knife away from you through the sharpening slots.
