Regular maintenance is crucial for extending the service life of electric window openers. It is recommended to inspect the motor, wiring, and guide rails every three months, promptly removing dust and debris; avoid overloading; and regularly lubricate mechanical components to ensure smooth window operation.
Although door and window handles are small components, they directly affect daily usage convenience and safety.
