Thanks for purchasing Hobbywing XERUN D10 motor. This sensored brushless power system is very powerful, any improper usage can be dangerous and may damage the product and related devices. Please take your time and read through the following instructions before you start using the motor. We have the right to modify the product design, appearance, features and usage requirements without notification. We, Hobbywing, are only responsible for our product cost and nothing else are result of using our product. To avoid short circuits, ensure that all wires and joints must be well insulated before connecting the motor to related devices. Never allow this product or other electronic components to come in contact with water, oil, fuel or other electro-conductive liquids. If it happens, stop the use of the product immediately and let it dry carefully. Read through the manuals of all power devices and chassis and ensure the power configuration is rational before using this unit. Never apply full throttle if the pinion gear is not mounted on, because (under the no-load circumstances) high RPMs may get the motor damaged. Please connect all the devices carefully, you may not control the vehicle properly or encounter some unpredictable issues like damaged components if any poor connection exists. To avoid possible damage (result from overheat) to the product, please control the soldering time within 5 seconds when soldering the motor wires (a soldering iron with the power of at least 60W is needed). Stop immediate usage once the casing of the motor exceeds 100°C/212°F as high temperature may damage the motor and cause the rotor to demagnetize. Hobbywing recommends activating the “Motor Thermal Protection” (of the ESC).
