Setup
1. Battery Installation and Charging
The drill operates with an 18V Lithium-ion battery. Ensure the battery is fully charged before use.
- To install the battery: Align the battery with the base of the drill and slide it in until it clicks into place.
- To remove the battery: Press the release button on the battery pack and slide it out.
- To charge the battery: Connect the charger to a power outlet and then to the battery. Refer to the charger's instructions for charging indicators.
2. Attaching the Auxiliary Handle
For improved control and safety, especially during high-torque applications, attach the auxiliary handle.
- Slide the auxiliary handle onto the front of the drill body.
- Rotate the handle to tighten it securely in the desired position.
3. Installing/Removing Drill Bits or Screwdriver Bits
This drill features a 13mm keyless chuck.
- To install: Rotate the chuck counter-clockwise until the jaws are wide enough to insert the bit. Insert the bit fully and then rotate the chuck clockwise to tighten it securely.
- To remove: Rotate the chuck counter-clockwise to loosen the jaws and pull the bit out.
Operating Instructions
1. Forward/Reverse Button

- Push the button to the left for Forward rotation (for drilling and driving screws).
- Push the button to the right for Reverse rotation (for removing screws or jammed bits).
- When the button is in the center position, the trigger is locked (Static), preventing accidental operation.
2. Speed Control
- Stepless Speed Change: The trigger allows for variable speed control. Press the trigger lightly for slower speeds and harder for faster speeds.
- High and Low Speed Switch: Use the switch on top of the drill to select between two main speed ranges:
- Low Speed (0-1800rpm): For high-torque applications like driving large screws or drilling into tough materials.
- High Speed (0-4600rpm): For fast drilling in softer materials.
3. Torque Settings and Function Selection

- Torque Adjustment (20+3 settings): Rotate the numbered ring behind the chuck to select the desired torque level. Lower numbers provide less torque, suitable for driving small screws or delicate materials. Higher numbers provide more torque for larger screws or harder materials. The "3" settings refer to the function modes.
- Function Selection: The drill offers three primary functions, indicated by icons on the adjustment ring:
- Screwdriver Mode: For driving and removing screws. Use with appropriate torque settings.
- Drill Hole Mode: For drilling holes in wood, metal, and plastic without impact.
- Rotary Hammer Mode: For drilling into masonry or concrete with impact action.
4. LED Work Light
The integrated LED light automatically illuminates when the trigger is pressed, providing increased visibility in dimly lit work areas. It remains on for approximately 10 seconds after the trigger is released.
5. Applications

- Screws: Driving various types of screws into wood, plastic, or metal.
- Drill Metal: Creating holes in metal sheets or profiles.
- Drill Wood: Drilling holes in wooden materials.
- Drill Ice: Specialized drilling, typically with an ice auger attachment (ensure proper bit and technique).
Maintenance
Regular maintenance ensures the longevity and optimal performance of your tool.
- Cleaning: Keep the ventilation openings clear and clean. Regularly wipe down the tool with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Battery Care: Store batteries in a cool, dry place away from direct sunlight. Do not store fully discharged batteries for extended periods. Charge them periodically if not in use.
- Chuck Maintenance: Keep the chuck jaws clean and free of debris to ensure proper bit gripping.
- Inspection: Periodically inspect the tool for any signs of damage, loose screws, or worn parts. If any issues are found, discontinue use and seek professional repair.
Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Drill does not start | Battery not charged or improperly installed; Forward/Reverse button in static (locked) position. | Ensure battery is charged and correctly inserted. Move the Forward/Reverse button to either forward or reverse position. |
| Loss of power during operation | Battery charge is low. | Recharge the battery. |
| Bit slips in chuck | Chuck not tightened sufficiently; Chuck jaws are dirty. | Tighten the chuck firmly. Clean the chuck jaws. |
