• Inspection: Regularly inspect the motor and pinion gear for any signs of wear or damage. Replace worn parts as necessary.

6. Safety Precautions

Adhere to the following safety precautions to prevent injury or damage:

• Heat Warning: The motor generates significant heat during operation. Excessive motor heat can deform the chassis. Avoid prolonged continuous use without cooling periods. Do not touch the motor directly after operation.
• Child Safety: Keep all parts, especially small components and packaging materials, out of reach of small children. There is a risk of accidental ingestion.
• Assembly: Exercise caution during assembly, particularly with metal parts, as they may have sharp edges.
• Proper Use: Improper use or installation can lead to motor damage or chassis deformation. Always follow instructions.
