2. General Safety Information
WARNING: Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.
2.1 Work Area Safety
- Keep the 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. Power tools create sparks which may ignite the dust or fumes.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2.2 Electrical Safety
- Power tool plugs must match the outlet. Never modify the plug in any way.
- Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
2.3 Personal Safety
- Always wear eye protection. Use safety glasses or goggles.
- Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.
- Stay alert, watch what you are doing, and use common sense when operating a power tool.
2.4 Power Tool Use and Care
- Do not force the power tool. Use the correct power tool for your application.
- Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools.
- Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
2.5 Battery Tool 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.
- Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
- When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
- Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

- To Remove: Press the battery release button (usually located at the front of the battery pack) and slide the battery pack out of the tool.
4.3 Installing and Removing Drill/Screwdriver Bits
- Ensure the tool is switched off and the battery is removed before changing accessories.
- Grip the rear half of the chuck and rotate the front half counter-clockwise until the chuck jaws are open wide enough to insert the bit.
- Insert the desired drill bit or screwdriver bit fully into the chuck.
- Rotate the front half of the chuck clockwise to tighten the jaws securely around the bit. Hand-tighten firmly.
- To Remove: Rotate the front half of the chuck counter-clockwise to loosen the jaws and pull the bit out.
5. Operating Instructions
5.1 Power On/Off and Speed Control
- The tool is switched ON by pressing the variable speed trigger switch. The tool speed increases as you increase pressure on the trigger.
- The tool is switched OFF by releasing the trigger switch.
5.2 Forward/Reverse Control
The forward/reverse slider switch is located above the trigger. Push the slider to the left for forward rotation (for drilling and screwdriving) and to the right for reverse rotation (for removing screws).
WARNING: Do not change the direction of rotation while the motor is running.
5.3 Autosense Technology and Mode Selection
The ASD18K-QW features Autosense technology, which automatically detects the material and screw type during screwdriving to prevent overtightening or stripping. The digital display allows you to select between drilling and screwdriving modes and shows the battery charge status.

- Selecting Mode: Use the digital display buttons to toggle between "Drill Mode" and "Screwdriver Mode".
- Screwdriver Mode (Autosense): When in screwdriver mode, the tool will automatically sense the resistance and stop when the screw is flush with the surface, or when the desired depth is reached. It also allows for gradual screw sinking with 1/4 turn increments for precise control.
- Drill Mode: In drill mode, the tool operates at full power for drilling holes.
- Battery Indicator: The digital display also shows the current battery charge level.
5.4 Drilling
- Select "Drill Mode" on the digital display.
- Secure the workpiece to prevent it from rotating.
- Position the drill bit at the desired location.
- Start the drill at a low speed and gradually increase pressure and speed as the bit penetrates the material.
- Maintain a firm grip on the tool.
5.5 Screwdriving
- Select "Screwdriver Mode" on the digital display.
- Ensure the correct screwdriver bit is installed for the screw type.
- Place the bit into the screw head and apply light, steady pressure.
- Press the trigger. The Autosense technology will manage the torque to drive the screw appropriately.
- For fine adjustments, utilize the 1/4 turn increments feature in screwdriver mode.
