Setup
- Battery Installation: Ensure the tool is off. Align the M12 battery with the tool's battery port and slide it in until it clicks securely into place. To remove, press the release tab and slide the battery out.
- Blade Installation: Refer to the tool's specific instructions for blade changes. Typically, this involves disengaging the spindle lock, using a wrench to loosen the arbor nut, replacing the cutting disc, and then re-tightening the nut and releasing the spindle lock. Always use the correct blade type and size for your application.
- Guard Adjustment: The tool features an adjustable guard. Rotate the guard to the desired position to ensure maximum protection while allowing for the necessary cutting depth and angle. Ensure the guard is securely locked before operation.
Operating Instructions
- Powering On/Off: To start the tool, press the safety lock-off button (if present) and then squeeze the trigger. Release the trigger to turn the tool off.
- Forward/Reverse Rotation: The M12FCOT-0 features a directional switch for forward and reverse rotation. Select the appropriate direction to control debris expulsion, directing sparks and dust away from the user or sensitive areas.
- Cutting Techniques: Always wear appropriate personal protective equipment (PPE), including eye protection, gloves, and hearing protection. Hold the tool firmly with one hand. Allow the blade to reach full speed before engaging the workpiece. Apply steady, even pressure and let the tool do the work. Avoid forcing the cut, which can lead to kickback or damage to the tool/blade.
- LED Work Light: The integrated LED work light illuminates the work surface, improving visibility in dimly lit areas.
Maintenance
- Cleaning: Regularly clean the tool's ventilation openings to prevent overheating. Use a soft, dry cloth. Do not use water or chemical cleaning agents.
- Blade Replacement: Replace worn or damaged cutting blades promptly. Always ensure the tool is disconnected from its power source (battery removed) before changing blades.
