1. Important Safety Instructions
Always observe basic safety precautions when using electric tools to reduce the risk of fire, electric shock, and personal injury. Read all instructions before operating this product.
- 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 such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
- Personal Safety: Always wear eye protection. Use personal protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection when appropriate. Stay alert, watch what you are doing, and use common sense when operating a power tool.
- 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 the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.
- Battery Tool Use and Care: Recharge only with the charger specified by the manufacturer. Use power tools only with specifically designated battery packs.

3. Setup
3.1 Charging the Battery
- Connect the charger to a suitable power outlet.
- Insert the battery pack into the charger. Ensure it clicks into place.
- The charging indicator light on the charger will show the charging status. Refer to the charger's specific instructions for light indications.
- Once fully charged, remove the battery pack from the charger.
3.2 Installing/Removing the Battery Pack
- Installation: Slide the charged battery pack into the base of the tool until it clicks securely into place.
- Removal: Press the battery release button (usually located on the side of the battery) and slide the battery pack out of the tool.
3.3 Installing/Removing Drill Bits or Screwdriver Bits
- Ensure the tool is switched off and the battery is removed for safety.
- Rotate the chuck counter-clockwise to open the jaws.
- Insert the desired drill bit or screwdriver bit fully into the chuck.
- Rotate the chuck clockwise to tighten the jaws firmly around the bit. Ensure the bit is centered and secure.
- To remove, rotate the chuck counter-clockwise and pull the bit out.
4. Operating Instructions
4.1 Powering On/Off and Speed Control
- To turn the tool on, press the trigger switch. The tool speed increases as you press the trigger further.
- To turn the tool off, release the trigger switch.
4.2 Forward/Reverse Rotation
The forward/reverse switch is located above the trigger. Push it to the left for forward rotation (for drilling and driving screws) and to the right for reverse rotation (for removing screws or freeing jammed bits).
4.3 Torque Settings (for Driving Screws)
The torque setting ring allows you to adjust the amount of torque applied before the clutch disengages. This prevents overtightening screws or damaging the workpiece. Rotate the ring to select the desired torque level. Start with a lower setting and increase as needed.
4.4 Mode Selection (Drilling vs. Impact Driving)
Use the mode selector to switch between drilling (drill bit icon) and impact driving (hammer icon) modes. Select the appropriate mode for your task.
4.5 Gear Speed Selection
The gear speed selector allows you to choose between two speed ranges:
- Gear 1 (Low Speed): Provides higher torque for driving large screws or drilling large holes.
- Gear 2 (High Speed): Provides higher speed for smaller drilling tasks or faster driving.
4.6 General Operation Tips
- Always hold the tool firmly with both hands if possible, especially during high-torque applications.
- Apply steady, even pressure. Do not force the tool.
- For drilling, start with a pilot hole if necessary, especially in hard materials or near edges.
