5. Naudojimo instrukcijos

For optimal performance and safety, adhere to the following operating guidelines:

1. Saugus ruošinys: Visada klamp the material firmly to prevent movement during the cut. Unsecured material can cause kickback and damage the blade or machine.
2. Pradėti pjūklą: Allow the saw blade to reach its full operating speed (up to 1800 RPM) before beginning the cut.
3. Controlled Feed Rate: Apply steady, consistent pressure. Do not force the blade through the material. Let the blade's teeth do the work. Forcing the cut can lead to premature dulling, tooth loss, and overheating.
4. Coolant/Lubricant (for Aluminum): When cutting aluminum, apply a suitable cutting lubricant to the blade to prevent material buildup and improve cut quality.
5. Venkite perkaitimo: If the blade becomes excessively hot, allow it to cool before continuing. Overheating can reduce blade life and performance.
6. Išvalyti šiukšles: Ensure the cutting area is clear of debris before and after each cut.
