4. Configuración
4.1 Instalación da batería
The SEESII Impact Driver is compatible with Makita 18V lithium-ion batteries. To install the battery, align the battery pack with the base of the tool and slide it in until it clicks securely into place. To remove, press the release button on the battery and slide it out.
Instalación de 4.2 bits
To install a driver bit, pull the bit holder forward, insert the bit fully into the chuck, and then release the bit holder. Ensure the bit is securely locked in place by gently pulling on it. To remove, pull the bit holder forward and pull the bit out.

5. Instrucións de funcionamento
5.1 Encendido/apagado
To power on the tool, simply press the trigger. The tool will start rotating. Release the trigger to stop the tool. For safety, ensure the forward/reverse switch is in the neutral (locked) position when not in use to prevent accidental startup.
5.2 Selección de modo
The impact driver features 4-speed settings and 4 smart modes. Use the mode selection button (often located near the battery indicator) to cycle through the available modes. The LED indicators will show the currently selected mode. The tool also has a memory function that recalls the last used mode.
- Configuración de 4 velocidades: Adjust the maximum rotation speed (Fastest, Strong, Medium, Weak) for different materials and fastener types.
- 4 Smart Modes: Specific modes optimized for wood, bolts, thin Tekus boards, and thick Tekus boards. These modes automatically adjust impact and rotation for optimal results and to prevent damage.
5.3 Variable Speed and Forward/Reverse
The trigger allows for variable speed control; the harder you press, the faster the tool rotates. The forward/reverse switch, located above the trigger, allows you to change the direction of rotation. Push it to the left for forward (tightening) and to the right for reverse (loosening). Position it in the middle to lock the trigger for safety.
5.4 Luz de traballo LED
The integrated 4-eye LED light automatically illuminates when the trigger is pressed, providing clear visibility of the work area. This feature is particularly useful in dimly lit environments.
6. Mantemento
Regular maintenance ensures the longevity and optimal performance of your SEESII Impact Driver.
