SANDING AND GRINDING TIPS
• Do not force the disc or stone against the material.
• The key to efficient grinding is to control the pressure and surface
contact between the grinding tool and the workpiece.
• Allow the tool to reach full speed before grinding.
• Avoid overloading the grinder. If it becomes hot during use, rest for a
few minutes while it cools down.
