Important Safety Information
Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury. Keep this manual for future reference.
- Read all instructions: Familiarize yourself with the tool's controls and proper usage.
- Wear personal protective equipment (PPE): Always wear safety glasses, hearing protection, and suitable gloves when operating the drill driver.
- Keep work area clean and well-lit: Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres: Do not use near flammable liquids, gases, or dust.

Accessory Installation (Drill Bits/Driver Bits)
- Ensure the drill is switched off and the forward/reverse switch is in the center (locked) position.
- Rotate the chuck counter-clockwise to open the jaws.
- Insert the desired drill bit or driver bit into the chuck, ensuring it is centered.
- Rotate the chuck clockwise to tighten the jaws firmly around the bit. Hand-tighten only; do not use a wrench.
Auxiliary Handle Adjustment

Operating Instructions
Powering On/Off
- To turn on the drill, press the trigger switch. The speed increases with trigger pressure.
- To turn off, release the trigger switch.
Speed Selection
The drill features a 2-speed gearbox:
- Speed 1 (Low Speed/High Torque): Ideal for driving screws and drilling large diameter holes.
- Speed 2 (High Speed/Low Torque): Suitable for drilling small diameter holes.
Slide the speed selector switch located on top of the drill to choose the desired speed setting.
Torque Settings
The torque adjustment ring allows you to select from 24 torque settings, plus drill and hammer drill modes. Rotate the ring to the desired setting:
- Settings 1-23: For driving screws into various materials. Start with a lower setting and increase as needed to prevent over-tightening or stripping screws.
- Drill Symbol: For general drilling without hammer action.
- Hammer Drill Symbol: For drilling into masonry and concrete.
Forward/Reverse Rotation
The forward/reverse switch is located above the trigger. Push it to the left for forward rotation (drilling/driving) and to the right for reverse rotation (removing screws/bits). The center position locks the trigger for safety.
Working with the Drill Driver
- Always hold the drill driver firmly with both hands, especially when using the hammer function or drilling large holes.
- Apply steady, even pressure. Do not force the tool.
- For drilling, start with a slow speed to create a pilot hole, then increase speed as needed.
- When driving screws, use the appropriate torque setting to avoid damaging the screw head or workpiece.
Maintenance
General Cleaning
- After each use, wipe the tool with a clean, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Keep the ventilation openings clear of dust and debris to prevent overheating. Use compressed air if necessary.
Battery Care and Storage
- Store batteries in a cool, dry place, away from direct sunlight and extreme temperatures.
- Do not store batteries in a discharged state for extended periods. Charge them periodically if not in use.
- Protect battery terminals from short-circuiting.
Chuck Maintenance
Periodically inspect the chuck jaws for wear or damage. Clean any dust or debris from the chuck mechanism to ensure smooth operation.
Inspection for Wear and Tear
Regularly inspect the power tool for any signs of damage, loose screws, or worn parts. If any damage is found, discontinue use and have the tool repaired by a qualified service technician.
