Package includes: 1 x Speed Controller How to use: 1. Turn off the power, connect it according to the wiring diagram and make sure the connection is correct. 2. Fix the controller tightly and set the speeds to the lowest "0", in order to avoid sudden large current and permanent damage when starting the power supply; 3. Then turn the device on and set the speed knob to the desired position. Please turn off the power when you don't need it; 4. The regulator is connected to the motor. If torque or speeds prove incompatible with requirements, please adjust the fine adjustment potentiometer on the side of the product 5. To change the direction of the engine, simply replace the jumper lines of "CCW" and "CW" on the back of the controller. 6. Select the short connection COM and CW, then the motor will turn clockwise. 7. Select the short connection COM and CCW, and then the motor rotates counterclockwise. (When changing direction, do not change direction until the engine has stopped completely.) Package List
