2. Información de seguridad

Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury. Keep this manual and all safety warnings for future reference.

Advertencias generales de seguridad para herramientas eléctricas:

• Seguridad en el área de trabajo: Mantenga el área de trabajo limpia y bien iluminada. Las áreas desordenadas u oscuras son una invitación a los accidentes.
• Seguridad eléctrica: No exponga las herramientas eléctricas a la lluvia ni a condiciones húmedas. Si entra agua en una herramienta eléctrica, aumentará el riesgo de descarga eléctrica.
• Seguridad personal: Always wear eye protection (safety glasses or goggles) and hearing protection (ear muffs or earplugs) when operating the saw. Use a dust mask if operating in dusty conditions.
• Uso y cuidado de herramientas: No fuerce la herramienta eléctrica. Utilice la herramienta eléctrica adecuada para su aplicación. Hará el trabajo mejor y más seguro al ritmo para el que fue diseñado.
• Uso y cuidado de la herramienta a batería: Use the tool only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• Servicio: Haga que un técnico calificado realice el mantenimiento de su herramienta eléctrica y utilice únicamente piezas de repuesto idénticas. Esto garantizará que se mantenga la seguridad de la herramienta eléctrica.

Advertencias de seguridad específicas para sierras circulares:

• Sostenga la herramienta firmemente with both hands. Always use the auxiliary handle if provided.
• Mantenga las manos alejadas del área de corte y de la cuchilla. Mantenga la segunda mano en la manija auxiliar o en la carcasa del motor. Si ambas manos sostienen la sierra, la hoja no podrá cortarlas.
• No meta la mano debajo de la pieza de trabajo. El protector no puede protegerlo de la hoja que está debajo de la pieza de trabajo.
• Ajustar la profundidad de corte to the thickness of the workpiece. Less than a full tooth of the blade should be visible below the workpiece.
• Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform. It is important to support the workpiece properly to minimize body exposure, blade binding, or loss of control.
• Use extreme caution when cutting into existing walls or other blind areas. La cuchilla que sobresale puede cortar objetos que pueden provocar un contragolpe.
• ADVERTENCIA: Using fake or knock-off batteries is dangerous, voids your warranty, and offers poor performance. Always use genuine Makita batteries.
• Extracción de polvo: When connecting to a vacuum system, ensure it is an anti-static system to prevent static charge buildup, which can damage the tool's control board.

• Freno eléctrico: Stops the blade rapidly after the trigger is released, enhancing operator safety.
• Boquilla para polvo: Allows connection to a vacuum system for improved dust extraction.
• Trigger Lock-Off Button: Prevents accidental startup of the saw.
• Protector de la hoja: Retracts during cutting and covers the blade when not in use for safety.
• Palanca de ajuste de profundidad: Para ajustar la profundidad de corte deseada.
• Palanca de ajuste de bisel: For setting the desired bevel angle (0° to 50°).
• Guide Rule: Used for making straight cuts parallel to an edge.
• Indicador de batería: Displays the remaining battery capacity.

4. Configuración

4.1 Instalación y extracción de la batería

This tool is designed for use with Makita 18V LXT Lithium-Ion batteries (sold separately). Ensure the battery is fully charged before use.

• Para instalar: Align the battery pack with the battery housing on the saw. Slide the battery into place until it locks with a click.
• Para eliminar: Presione el botón de liberación del paquete de baterías y deslícelo fuera de la herramienta.

4.2 Instalación y extracción de la cuchilla

Always disconnect the battery before installing or removing the blade.

1. Ensure the saw is unplugged or the battery is removed.
2. Presione el botón de bloqueo del eje para evitar que la cuchilla gire.
3. Use the provided hex wrench to loosen the blade bolt by turning it counter-clockwise.
4. Retire el perno de la cuchilla, la brida exterior y la cuchilla vieja.
5. Clean any sawdust or debris from the blade area.
6. Install the new 6-1/2" C.T. Blade (24T, A-85092) or a compatible blade, ensuring the teeth are pointing in the direction of rotation indicated on the saw.
7. Replace the outer flange and blade bolt. Tighten the blade bolt securely by turning it clockwise while pressing the shaft lock button.
8. Ensure the blade guard moves freely.

4.3 Ajuste de la profundidad de corte

The cutting depth should be set so that the blade extends slightly below the workpiece to ensure efficient cutting and minimize kickback.

1. Afloje la palanca de ajuste de profundidad.
2. Suba o baje la base de la sierra para lograr la profundidad de corte deseada.
3. Align the desired depth marking on the scale with the indicator.
4. Apriete firmemente la palanca de ajuste de profundidad.

5.2 Técnicas de corte

• Cortes rectos: Use the guide rule or a clamped straight edge for accurate straight cuts.
• Cortes biselados: Adjust the bevel angle as described in Section 4.4.
• Cortes de inmersión: For plunge cuts, ensure the blade guard is fully retracted before slowly lowering the saw into the workpiece.
• Material de corte: The saw is ideal for cutting wood and wood-based materials. Ensure the correct blade is used for the material.
