Congratulations and thank you for your trust in Hobbywing product. By purchasing the XERUN XD10 Pro, you have chosen a high performance sensored brushless electronic speed controller! This speed controller is equipped with high-tech features to enhance your experience with Hobbywing brushless power systems. To avoid short circuits, ensure that all wires and connections must be well insulated beforeconnecting the ESC to related devices. Ensure all devices are well connected to prevent poor connections and avoid damage to your electronic devices. Read through the manuals of all power devices and chassis and ensure the power configuration is rational before using this unit. Please use a soldering iron with the power of at least 60W to solder all input/output wires and connectors. Do not hold the vehicle in the air and rev it up to full throttle, as rubber tires can “expand” to extreme size or even crack to cause serious injury. Stop immediate usage once the casing of the ESC exceeds 90°C/194°F as this may cause damage to both the ESC and motor. Hobbywing recommends setting the “ESC Thermal Protection” to 105°C/221°F (this refers to the internal temperature of the ESC). Users must always disconnect the batteries after use as the current on the ESC is consuming continuously if it is connected to the batteries (even if the ESC is turned off). The battery will completely be discharged and may result in damage to the battery or ESC when it is connected for a long period of time. This WILL NOT be covered under warranty.
