4. Setup
Proper installation of the diamond blade is crucial for safety and performance. Always refer to your power tool's instruction manual for specific blade changing procedures.
- Power Disconnection: Ensure the power tool is unplugged or its battery is removed before attempting to install or remove the blade.
- Blade Inspection: Before mounting, visually inspect the Faithfull FAIDB300PRO blade for any signs of damage, such as cracks, chips, or warping. Do not use a damaged blade.
- Compatibility Check: Verify that the blade's bore size (20mm) and maximum RPM (5100rpm) are compatible with your power tool. This blade is suitable for use on wall chasers, petrol cutters, bridge saws, table saws, tile saws, and angle grinders.
- Mounting: Place the blade onto the spindle of the power tool, ensuring the arrow indicating the direction of rotation on the blade matches the rotation direction of the tool.
- Secure Fastening: Use the appropriate flanges and tightening nut to secure the blade firmly. Do not overtighten.
- Test Spin: After installation, briefly run the tool in a safe area to ensure the blade is properly seated and runs without excessive wobble or vibration.
5. Operating Instructions
Follow these guidelines for effective and safe operation of your Faithfull diamond cutting blade:
- Workpiece Security: Always secure the material you are cutting to prevent movement during operation.
- Starting the Cut: Allow the power tool to reach full operating speed before engaging the blade with the workpiece.
- Cutting Technique: Apply steady, moderate pressure. Avoid excessive force, which can overheat the blade, reduce cutting efficiency, and shorten blade life. Let the diamond segments do the work.
- Dry/Wet Application: This blade is designed for both dry and wet cutting applications. For wet cutting, ensure adequate water flow to cool the blade and suppress dust. Wet cutting generally extends blade life and provides a cleaner cut.
- Cooling Breaks: For dry cutting, especially on hard materials, take periodic breaks to allow the blade to cool down. Running the blade freely in the air for a few seconds can help dissipate heat.
- Dust Control: When dry cutting, use appropriate dust extraction equipment or work in a well-ventilated area to minimize inhalation of dust particles.
6. Maintenance
Regular maintenance ensures optimal performance and safety of your diamond blade.
- Cleaning: After each use, clean the blade to remove any accumulated debris or slurry. For wet cutting, rinse thoroughly with water. For dry cutting, use a brush to remove dust.
- Inspection: Periodically inspect the diamond segments for wear. When the diamond segments are significantly worn down, or the steel core becomes exposed, the blade should be replaced. Check for any signs of cracks in the steel core or segment loss.
- Storage: Store the blade in a dry environment to prevent rust. Keep it protected from impacts that could damage the segments or warp the blade.
