    • Be careful not to damage the line (E) or other parts.
    • Do not use tools.
    • If the connector does not move, keep the retainer tabs pressed down, and alternately pull and push the connector until it comes off easily.
    • Do not remove the retainer from the line; once removed, the retainer must be replaced with a new one.
