5. Operating Instructions
5.1. Power Drill Operation
- Forward/Reverse Switch: Located above the trigger, push left for forward rotation (drilling/driving screws) and right for reverse rotation (removing screws). Center position locks the trigger for safety.
- Variable Speed Trigger: Squeeze the trigger to start the drill. The speed increases with greater pressure on the trigger.
- LED Light: The integrated LED light illuminates the work area when the trigger is pressed.
- Torque Adjustment: The collar behind the chuck allows adjustment of the torque setting (64+1 positions, max 32N.m). Use lower settings for driving screws into softer materials and higher settings for harder materials or drilling.
- 2-Speed Setting: A switch on top of the drill allows selection between two speed ranges. Position 1 is for lower speed, higher torque applications (e.g., driving screws). Position 2 is for higher speed, lower torque applications (e.g., drilling).

5.2. Using Hand Tools
The tool set includes a variety of hand tools for different tasks:
- Screwdrivers: Use the appropriate head type (Phillips, flathead) and size for screws.
- Pliers: For gripping, bending, or cutting wires. Select the correct type (e.g., needle-nose, slip-joint) for the task.
- Hammer: For driving nails or light demolition. Always wear safety glasses.
- Measuring Tape: For accurate measurements.
- Utility Knife: For cutting various materials. Always use with caution and retract the blade when not in use.
- Adjustable Wrench: For tightening or loosening nuts and bolts. Adjust the jaw opening to fit the fastener.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Drill does not start. | Battery not charged or not properly inserted. Trigger lock engaged. | Charge battery fully and ensure it is securely inserted. Disengage the trigger lock by centering the forward/reverse switch. |
| Loss of power during operation. | Battery charge is low. Overload protection activated. | Recharge the battery. Reduce pressure on the drill or use a lower speed/torque setting. |
| Bit slips in chuck. | Chuck not tightened sufficiently. Bit shank is dirty or damaged. | Ensure chuck is tightened firmly. Clean or replace the drill bit. |
