How to use

Before installation, ensure that the angle grinder is disconnected from the power source. Secure the disc onto the spindle using the appropriate flange and locking nut, ensuring it is centered correctly.

• Verify that your angle grinder is compatible with 125 mm diameter discs
• Ensure the tool's maximum RPM does not exceed the disc's safety limit
• Always use appropriate personal protective equipment, including eye and ear protection
• Check that the disc is suitable for the specific type of metal you intend to cut

Usage recommendations

Always wear safety goggles, gloves, and a dust mask when operating an angle grinder. Inspect the disc for any cracks or damage before each use and replace it immediately if any defects are found. Store the discs in a dry, cool place to maintain their structural integrity.
