2. Safety Instructions

WARNING: Always follow basic safety precautions to reduce the risk of fire, electric shock, and serious personal injury.

• Personal Protective Equipment: Always wear eye protection (safety glasses or goggles), hearing protection, and heavy-duty gloves. A face shield is also recommended due to sparks and debris.

4. Setup

4.1 Unpacking and Inspection

1. Carefully remove the saw from its packaging.
2. Inspect the tool for any damage that may have occurred during shipping. Do not operate if damaged.
3. Ensure all included accessories are present: abrasive wheel, socket wrench, and switch button.

4.2 Securing the Saw

Place the saw on a stable, level workbench. The base of the saw has mounting holes if permanent securing is desired for increased stability during heavy use.

4.3 Adjusting the Guide Plate (Fence)

The guide plate can be adjusted 45 degrees right and left to accommodate various material sizes and angle cuts. It features three locations for different material dimensions.

1. Loosen the bolts securing the guide plate.
2. Slide the guide plate to the desired angle or position.
3. Tighten the bolts securely to prevent movement during cutting.

4.4 Installing/Changing the Abrasive Wheel

Always ensure the saw is unplugged before changing the abrasive wheel.

1. Press and hold the shaft lock button to prevent the shaft from rotating.
2. Use the provided socket wrench to loosen and remove the arbor nut.
3. Remove the old abrasive wheel and replace it with a new 14-inch abrasive wheel with a 1-inch arbor.
4. Ensure the wheel is seated correctly on the flanges.
5. Tighten the arbor nut firmly with the socket wrench while holding the shaft lock button. Do not overtighten.

5. Operating Instructions

5.1 Preparing the Workpiece

1. Place the material to be cut against the guide plate.
2. Use the quick-release vise to firmly clamp the workpiece. Ensure it is stable and will not move during the cut.
3. Adjust the depth stop if a specific cutting depth is required.

5.2 Making a Cut

1. Ensure all safety precautions are observed, including wearing appropriate PPE.
2. Plug the saw into a suitable 115V power outlet.
3. To start the saw, press the lock-off button and then squeeze the trigger switch.
4. Allow the abrasive wheel to reach full speed before beginning the cut.
5. Slowly and steadily lower the saw blade through the workpiece. Do not force the cut; let the saw do the work.
6. Once the cut is complete, release the trigger switch and allow the blade to stop completely before raising the saw arm.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your saw.

• Cleaning: After each use, unplug the saw and clean off dust and debris, especially from the motor vents, using a dry cloth or compressed air.
• Abrasive Wheel Inspection: Regularly inspect the abrasive wheel for wear, cracks, or damage. Replace worn or damaged wheels immediately.
• Carbon Brushes: Periodically check the carbon brushes for wear. Replace both brushes when either is worn down to the limit mark. Refer to a qualified service technician for brush replacement if you are unsure.
• Cord Inspection: Inspect the power cord for damage. Do not use the saw if the cord is frayed or cut.
• Lubrication: This tool is designed for maintenance-free operation regarding lubrication. Do not apply oil or grease to internal components.

7. Troubleshooting

If you encounter issues with your Makita 2414NB, refer to the following common problems and solutions:

• Saw does not start:
  • Check if the power cord is securely plugged into a live outlet.
  • Ensure the lock-off button is pressed before squeezing the trigger.
  • Check the circuit breaker or fuse.
  • Inspect carbon brushes for wear.
• Excessive sparks or slow cutting:
  • The abrasive wheel may be worn or incorrect for the material. Replace if necessary.
  • Ensure the workpiece is securely clamped.
