6. Operating Instructions

6.1 Powering On/Off

Press and hold the power button (usually marked with a circle and a vertical line) for a few seconds to turn the tool on or off. The digital display will illuminate when the tool is active.

6.2 Adjusting Speed

The tool features 6-stage variable speed control, ranging from 10000 to 18000 RPM. Use the speed adjustment buttons (often '+' and '-' or a single button to cycle through speeds) to select the desired RPM. Lower speeds are suitable for delicate tasks like fine polishing or deburring, while higher speeds are effective for grinding, cutting, or removing support structures from 3D prints.

6.3 General Usage Tips

• Light Pressure: Apply light, consistent pressure. Excessive force can cause the tool to bog down, overheat, or damage the workpiece.
• Continuous Movement: Keep the tool moving to prevent burning or gouging the material.
• Material Compatibility: Select the correct accessory and speed for the material you are working on (e.g., PLA, ABS, resin, wood, soft metals).
• Post-Processing 3D Prints: This tool is ideal for smoothing rough edges, removing support material, deburring, and adding fine details to 3D printed models.
