5. Istruzioni per l'uso
Proper operation is crucial for effective sharpening and safety:
- Regolazione dell'angolo: Use the cutting edge angle det-up wheel and cutting angle setting wheel to set the desired sharpening angle (0-35°). Refer to your chainsaw chain's specifications for the correct angle.
- Adjusting Grinding Depth: Utilize the depth of grind set screw and limit screw to control the grinding depth. This ensures consistent results and prevents over-grinding.
- Securing the Chain: Place the chainsaw chain into the screw clamp cradle. Use the clamping lever and screw clamps to firmly secure the chain in position. Ensure the chain is stable and will not move during sharpening.
- Starting the Sharpener: Press the green ON button. The grinding wheel will begin to spin at 3000 RPM.
- Affilatura della catena: Gently bring the chain cutter into contact with the spinning grinding wheel. Apply light, consistent pressure. Sharpen each cutter evenly.
- Stopping the Sharpener: Once sharpening is complete, press the red OFF button. Allow the grinding wheel to come to a complete stop before handling the chain or making further adjustments.
