To use this wire seal kit, first, make sure your motor is turned off and disconnected from any power source. For the motor phase wires, simply slide the rubber seals onto each of the three motor phase wires of your Bafang BBS01 or BBS02 motor. When dealing with the hall sensor wire, remove the old gasket if it's damaged and replace it with the new rubber gasket provided in the kit. Remember, these seals won't fit the BBSHD motor phase wires, so double - check your motor type. To maintain the seals, keep them away from sharp objects that could cut or puncture them. Also, avoid exposing them to extreme temperatures or harsh chemicals as this could degrade the rubber over time.
