4.1 Mounting the Abrasive Wheel

1. Ensure your angle grinder is unplugged or its battery is removed.
2. Inspect the X-LOCK mechanism on both the grinder and the wheel for any debris. Clean if necessary.
3. Align the X-LOCK interface on the abrasive wheel with the X-LOCK spindle on the grinder.
4. Press the wheel firmly onto the spindle until you hear an audible 'snap', indicating it is securely locked in place. Gently tug on the wheel to confirm it is properly seated.
5. Adjust the grinder's guard to ensure maximum protection for your specific application.
