2. Select Clamping Washer: Check your angle grinder's collar diameter and select the appropriate clamping washer/ring from the provided set.
3. Attach Shroud Base: Place the shroud's mounting pad onto the angle grinder spindle. Secure it by tightening the screw or clamping mechanism. Ensure it is firmly attached and does not wobble.
4. Install Cutting Blade: Carefully install the diamond cutting blade onto the grinder spindle, ensuring it is oriented correctly. Use the spanner wrench to tighten the blade nut securely.
5. Adjust Cutting Depth: The shroud features an adjustable cutting depth mechanism. Loosen the depth adjustment knob, set the desired cutting depth using the visible scale, and then securely tighten the knob. The maximum cutting depth is approximately 1-1/4 inches when using a 5-inch blade.

5. Operating Instructions

Once the dust shroud is securely installed and connected to a vacuum system, you can begin cutting operations:

• Power On: Turn on your vacuum cleaner first, then power on the angle grinder.
• Cutting: Guide the angle grinder with the attached shroud along your cutting line. The clear shroud allows for visibility of the cutting area, and the adjustable guide assists in maintaining straight cuts.
• Dust Control: The shroud is designed to capture dust effectively at the source, directing it into your connected vacuum system. This significantly reduces airborne particles.
• Material Compatibility: This dust shroud is suitable for cutting various materials including metal, stone, and wood, provided the correct blade is used.
• Depth Adjustment: The adjustable cutting depth allows for flexibility in various cutting tasks without needing to change tools frequently.
• Post-Operation: Once cutting is complete, turn off the angle grinder, then turn off the vacuum cleaner. Allow the blade to stop completely before setting the tool down.

• Inspection: Periodically inspect the shroud for cracks, damage, or excessive wear, especially around the clamping points and the clear viewing window.
• Storage: Store the dust shroud in a clean, dry place away from direct sunlight and extreme temperatures.

7. Troubleshooting

If you encounter issues with your dust shroud, consider the following:
