3. Safety Instructions
Always follow basic safety precautions when using power tools to reduce the risk of injury, electric shock, and fire.
- 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: Avoid body contact with earthed or grounded surfaces (e.g., pipes, radiators, ranges, refrigerators). Do not expose power tools to rain or wet conditions.
- Personal Safety: Always wear eye protection. Use hearing protection when operating noisy tools. Dress properly; avoid loose clothing or jewelry that can get caught in moving parts.
- Tool Use and Care: Do not force the tool. Use the correct tool for your application. Disconnect the battery pack from the tool before making any adjustments, changing accessories, or storing power tools.
- Battery Safety: Only use the specified charger for the battery. Do not incinerate the battery even if it is severely damaged. Do not short-circuit the battery.
4. Setup
4.1 Battery Charging
- Ensure the 20V rechargeable battery is securely inserted into the drill or removed for charging.
- Connect the provided USB-C charging cable to the battery's charging port.
- Plug the other end of the USB-C cable into a universal charger or a 5V DC USB output.

- Power On/Off: Press the trigger switch to start the drill. Release to stop. The integrated LED light will activate when the trigger is pressed.
- Speed Adjustment: The drill features a variable speed trigger. Press lightly for slower speeds and harder for faster speeds. For precise control, use the speed selector switch (typically marked '1' and '2') located on top of the drill to choose between low-speed/high-torque (for driving screws) and high-speed/low-torque (for drilling).
- Direction Control: Use the forward/reverse switch (usually above the trigger) to select the rotation direction for drilling or driving/removing screws.
- Torque Setting: Adjust the torque collar (numbered ring behind the chuck) to prevent over-driving screws or damaging materials. Higher numbers provide more torque.
5.2 Using Hand Tools

Each hand tool in the DEKO kit is designed for specific tasks. Always select the appropriate tool for the job to ensure efficiency and safety. For example, use the claw hammer for driving and removing nails, the tape measure for accurate measurements, and the spirit level for ensuring surfaces are horizontal or vertical.
6. Maintenance
- Cleaning: After each use, wipe down all tools with a clean, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying.
- Lubrication: Periodically apply a light coat of oil to moving parts of pliers, wrenches, and other mechanical tools to prevent rust and ensure smooth operation.
- Storage: Always store tools in their designated slots within the durable case. This protects them from damage, prevents loss, and keeps them organized. Store the case in a dry, secure location away from direct sunlight and extreme temperatures.
- Battery Care: Store the battery in a cool, dry place. Do not store fully discharged batteries for extended periods. Charge the battery periodically if not in use for a long time.
