Operating Instructions
1. E-Tube Wire Installation and Removal
This tool is essential for safely connecting and disconnecting Shimano Di2 E-Tube wires, especially in confined spaces. The tool's design helps to apply even pressure, preventing damage to the wire connectors.
- For Removal: Gently insert the appropriate end of the TL-EW01 tool into the gap around the E-Tube wire connector. Apply slight leverage to carefully disengage the connector from its port. Avoid excessive force.
- For Installation: Align the E-Tube wire connector with its port. Use the tool to gently push the connector fully into place until it is seated securely. A subtle 'click' may be felt or heard, indicating a proper connection.
