3. Setup and Assembly

1. Unpacking: Carefully remove all components from the packaging. Inspect for any shipping damage.
2. Mounting: Securely bolt the bench grinder to a sturdy workbench using appropriate fasteners (not included). Ensure the grinder is stable and will not move during operation.
3. Tool Rests: Attach the tool rests to the grinder. Adjust them so they are approximately 1/16 inch (1.6 mm) from the grinding wheels and slightly below the center line of the wheel. Tighten securely.
4. Eye Shields: Install the transparent eye shields. Adjust their position to provide maximum protection without obstructing your view of the workpiece.
5. LED Light: Position the adjustable gooseneck LED light to illuminate your primary work area on the grinding wheel.
6. Power Connection: Ensure the power switch is in the "OFF" position. Plug the grinder into a standard 120 Volt AC grounded electrical outlet.

4. Operation

1. Pre-Operation Check: Before each use, verify that all guards, tool rests, and eye shields are properly installed and secured. Inspect grinding wheels for any damage.
2. Starting the Grinder: Turn the power switch to the "ON" position. Allow the grinder to reach full operating speed before beginning work.
3. Adjusting Speed: Use the infinite variable speed control to set the desired RPM (from 2000 RPM to 3600 RPM). Lower speeds are generally suitable for finer work or heat-sensitive materials, while higher speeds are for faster material removal.
4. Grinding Technique:
   • Hold the workpiece firmly against the tool rest.
   • Apply light, even pressure to the grinding wheel. Avoid jamming the workpiece into the wheel.
   • Move the workpiece across the face of the wheel to ensure even wear and prevent grooving.
   • For sharpening, maintain a consistent angle against the wheel.
   • Periodically cool the workpiece in water to prevent overheating and loss of temper.
5. Using the LED Light: Adjust the flexible gooseneck LED light to provide optimal illumination on your grinding area for improved precision and safety.
6. Stopping the Grinder: Turn the power switch to the "OFF" position. Wait for the wheels to come to a complete stop before leaving the machine unattended or performing any adjustments.

5. Maintenance

Regular maintenance ensures optimal performance and extends the life of your bench grinder. Always unplug the tool before performing any maintenance.

• Cleaning: Keep the grinder clean and free of dust and debris. Use a soft brush or compressed air to clean the motor vents and housing.
• Wheel Inspection: Regularly inspect grinding wheels for wear, cracks, or chips. Replace worn or damaged wheels promptly.
• Wheel Dressing: Use a wheel dresser to true and clean the grinding wheels, restoring their cutting efficiency and shape.
• Tool Rest Adjustment: Ensure tool rests remain properly adjusted to within 1/16 inch (1.6 mm) of the wheel.
