2. Característiques clau
- Disseny lleuger i compacte: Weighing 2.2kg (with BSL1240M battery), the saw is easy to handle, reducing user fatigue during extended operation.
- 18V Equivalent Cutting Speed: Equipped with a small, high-efficiency brushless motor and a standard Super Chip Saw Kuroshachi (125mm), it achieves cutting speeds comparable to 18V models, offering approximately 20% faster cutting than conventional products under specific conditions (wood cross-cutting, SPF 2x10 material, 20N pressing load).
- Optimized Handle Angle: The 28° handle angle provides improved workability, making it easier to apply force, especially when cutting thin materials.
- Low Vibration and Low Noise: Designed for reduced vibration and noise, enhancing user comfort and making it suitable for various work environments, including indoors and residential areas.
- Improved Switch Lock Operability: A tapered switch lock button design makes it easier to press and operate.
- High-Brightness LED Light: Integrated LED light illuminates the cutting area for improved visibility.
- Kickback Reduction System: Helps to mitigate kickback during operation. Users must ensure materials are securely fixed and the tool is held firmly.
- New Parallelism Adjustment Link Structure: Allows for smooth vertical adjustment of the base, ensuring precise cuts.
- Funció de ventilador: Clears sawdust from the cutting line, maintaining visibility and accuracy.
- Funció de tall de vores: The sub-base can be removed to enable reverse 15° edge cutting.

- Utilitzeu l'equip de protecció individual (EPI) adequat, com ara ulleres de seguretat, protecció auditiva i guants.
- Assegureu-vos que la peça de treball estigui ben ferma clamped o subjectat per evitar moviment durant el tall.
- Keep hands and body clear of the cutting blade.
- No utilitzeu la serra a damp o condicions humides.
- Desconnecteu sempre la bateria abans de fer qualsevol ajust, canviar accessoris o guardar l'eina.
- Use only HiKOKI recommended accessories and replacement parts.
5. Configuració
5.1 Instal·lació i extracció de la bateria
- To install the battery, align the battery pack with the receptacle on the saw and slide it in until it clicks into place.
- To remove the battery, press the battery release button and slide the battery pack out.
5.2 Instal·lació i extracció de la fulla
- Ensure the battery is removed before changing the blade.
- Premeu el botó de bloqueig del fus per fixar la fulla.
- Use the hex wrench to loosen the blade bolt.
- Traieu la brida exterior i la fulla antiga.
- Install the new 125mm Super Chip Saw Kuroshachi blade, ensuring the teeth are pointing in the direction of rotation.
- Replace the outer flange and tighten the blade bolt securely with the hex wrench while holding the spindle lock.
5.3 Ajust de la profunditat de tall i l'angle de bisell
- Profunditat de tall: Loosen the depth adjustment lever, raise or lower the base to the desired cutting depth, and then tighten the lever.
- Angle de bisell: Loosen the bevel adjustment lever, tilt the saw base to the desired angle (up to 45°), and then tighten the lever.
6. Funcionament
6.1 Arrencada i aturada de la serra
- To start the saw, press the switch lock button and then pull the trigger switch.
- Per aturar la serra, deixeu anar l'interruptor del disparador.
6.2 General Cutting Techniques
- Marqueu clarament la línia de tall a la peça de treball.
- Position the saw with the blade just above the workpiece, aligning the blade with the cutting line.
- Engegueu la serra i deixeu que la fulla arribi a la màxima velocitat abans d'engranar el material.
- Maintain a steady, even pressure and feed rate through the material. Avoid forcing the saw.
- Ensure proper support for the workpiece to prevent pinching the blade or kickback.
6.3 Using the Blower Function and Edge Cutting
- The integrated blower function automatically clears sawdust from the cutting line during operation.
- For edge cutting (reverse 15°), remove the sub-base as described in the manual. This allows for cuts closer to edges or walls.
