Motor Usage Guidelines:

• Operating Within Specifications: Always operate the motor within the specified voltage and current range. Using the motor outside these limits may reduce its lifespan.
• Handling the Motor: Use the motor casing when moving it and handle with care.
• Wiring: Connect the red wire to the positive terminal and the black wire to the negative. Reversed connections will make the motor rotate in the opposite direction.
• Overload: Operate the motor within the recommended load range. Avoid prolonged operation under stall conditions, as this can damage the motor.
• Storage Conditions: Store the motor at 0–40°C with 15–90% relative humidity. Avoid high temperatures, high humidity, and corrosive gases.
• Operating Temperature: 0–70°C
