2. Safety Instructions
Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury.
- Work Area Safety: Keep your work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Electrical Safety: Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- Personal Safety: Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication.
- Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. It will do the job better and safer at the rate for which it was designed. Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.
- Battery Pack Use and Care: Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

5. Setup
5.1. Charging the Battery
The screwdriver is powered by an integrated 4V 1.5Ah Li-ion battery. Before first use, fully charge the battery.
- Connect the USB charging cable to the charging port on the screwdriver.
- Plug the other end of the USB cable into a compatible USB power adapter (not included) or a USB port.
- The LED battery charge indicator will illuminate to show charging status. A full charge is indicated when all LED segments are lit or the indicator changes color (refer to specific LED behavior on your device).
- Once fully charged, disconnect the charging cable.
Note: Do not overcharge the battery. Unplug the charger once the battery is fully charged to prolong battery life.
5.2. Attaching Screw Tips and Adapters
The screwdriver features a magnetic chuck for quick and secure attachment of screw tips and adapters.
- Select the appropriate screw tip for your task.
- Insert the screw tip directly into the magnetic chuck until it is firmly seated.
- To attach an adapter (e.g., 45-degree angle adapter or edge strip adapter), align the adapter with the chuck and push it on until it clicks into place. Ensure it is securely fastened.
- To remove, pull the adapter or screw tip straight out from the chuck.
6. Operating Instructions
6.1. Basic Operation
Before operating, ensure the battery is charged and the correct screw tip or adapter is installed.
- Forward/Reverse Rotation: Locate the direction switch (usually near the trigger). Push it to the left for forward (tightening) rotation and to the right for reverse (loosening) rotation. Ensure the switch is in the neutral (middle) position when not in use to prevent accidental activation.
- Starting the Screwdriver: Press the trigger switch to activate the screwdriver. The double LED worklight will illuminate the work area automatically.
- Stopping the Screwdriver: Release the trigger switch to stop the screwdriver.
- Spindle Lock: When the trigger is released, the spindle automatically locks, allowing for manual tightening or loosening of screws if additional torque is required.
6.2. Using Adapters
The included adapters enhance the versatility of your screwdriver:
- 45-degree Angle Adapter: Use this adapter for driving screws in tight corners or confined spaces where a straight approach is not possible.
- Edge Strip Adapter: This adapter allows you to drive screws very close to an edge or surface, providing precise control in delicate applications.
Always ensure adapters are securely attached before use.
7. Maintenance
Regular maintenance ensures optimal performance and extends the life of your tool.
- Cleaning: Keep the ventilation openings of the tool clean to prevent overheating. Wipe the tool housing with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the screwdriver and its accessories in a dry, secure place, out of reach of children. Avoid storing in direct sunlight or extreme temperatures.
