1. Servo motors can be used in places that are susceptible to water or oil droplets, but they are not fully waterproof or oil resistant. Therefore, servo motors should not be placed or used in environments with water or oil invasion.2. If the servo motor is connected to a reduction gear, an oil seal should be added when using the servo motor to prevent oil from the reduction gear from entering the servo motor3. Do not immerse the cables of the servo motor in oil or water.
