- Connect the provided USB Type-C charging cable to the charging interface on the pen.
- Connect the other end of the USB cable to a compatible USB power adapter (not included) or a computer USB port.
- The Power Indicator Lights will show the charging status. Once fully charged, the lights will indicate a full battery.
A full charge allows for approximately one hour of continuous operation.
4.2 Installing/Changing Engraving Bits
- Ensure the engraving pen is turned OFF before changing bits.
- Loosen the Locking Collar by rotating it counter-clockwise.
- Insert the desired engraving bit into the collet. Ensure the bit is fully seated.
- Tighten the Locking Collar by rotating it clockwise until the bit is securely held. Do not overtighten.
- Gently pull on the bit to confirm it is firmly in place before operation.
5. Operating Instructions
5.1 Power On/Off and Speed Adjustment
- To power on the device, press and hold the On/Off & Speed Control Button for a few seconds until the Speed Indicator Lights illuminate.
- To adjust the speed, press the On/Off & Speed Control Button briefly. Each press will cycle through the three available speed levels:
- Low Speed (approx. 5,000 RPM)
- Medium Speed (approx. 10,000 RPM)
- High Speed (approx. 18,000 RPM)
- Select the appropriate speed based on the material and the task. Lower speeds are suitable for softer materials like plastic and leather, while higher speeds are for harder materials such as metal, wood, stone, and glass.
- To power off the device, press and hold the On/Off & Speed Control Button again for a few seconds until the lights turn off.
5.2 Engraving and Crafting Techniques
Always wear appropriate safety glasses when operating the tool.
- Material Preparation: Ensure your workpiece is clean and securely held. For delicate materials, practice on scrap pieces first.
- Grip: Hold the engraving pen like a regular pen for precise control.
- Pressure: Apply light, consistent pressure. Excessive force can activate the overload protection or damage the bit/material.
- Movement: Use smooth, controlled movements. For engraving, trace your design slowly. For grinding or polishing, move the tool evenly across the surface.
- Overload Protection: The built-in overload protection chip will automatically shut down the motor if resistance is too high. If this occurs, reduce pressure or check for obstructions, then restart the tool.
