Usage Guide – How to Use the Electric Sanding Pen

1. Charge the Tool: Connect the USB Type-C cable to the charging port. The tool charges to 80% in 30 minutes and fully charged in 60 minutes.
2. Select Your Drill Head: Insert a compatible drill head (3.0mm shank) or rod (up to 3mm) into the chuck.
3. Tighten with the Hex Wrench: Use the included hex wrench (stored in the tool's hexagonal wrench storage) to fasten the drill head securely.
4. Power On: Press the function button to power on the tool. Use the button to cycle through the 4 speed settings (1/2/3/4 gear).
5. Select Direction: Use the forward/reverse switch to change rotation direction as needed.
6. Begin Sanding: Apply light, even pressure. Let the tool do the work – avoid forcing the tool, which can cause overload and trigger the automatic shut-off.
7. Monitor Indicators: Check the power and load indicators. If the overload indicator lights up, reduce pressure – the tool will automatically power off after 2 seconds if overloaded.
8. Finish and Store: Power off when finished. Store the tool in a safe place – the anti-roll design helps prevent accidental damage.

Pro Tip: For best results, use a light touch and let the tool's speed do the work. Start with a lower speed setting for delicate work, and increase speed for heavier material removal. The surface after sanding is smooth without residue – use a high-grit number sandpaper to buff afterwards for a surface shine.
