Daily Cleaning Recommendations: It is recommended to regularly wipe the handle surface with a soft, damp cloth to remove dust and fingerprints. Please avoid using strong acids, strong alkalis, or abrasive chemical cleaners to prevent damage to the UV treatment layer or the texture of the coating.
Lock cylinder lubrication and maintenance: If the lock cylinder feels slightly stiff after prolonged use, you can inject a small amount of professional graphite lubricant powder or lock cylinder maintenance agent. **Do not** use cooking oil or machine oil, as this may cause dust accumulation and damage the lock cylinder.
Regular tightening and inspection: Due to the frequent opening and closing vibrations of the door, it is recommended to check the mounting screws of the WPC door lock every six months. If any loosening is found, please tighten them according to the professional video tutorial or manual provided by the company to ensure installation quality and product performance.
Avoid violent impact: Although the product structure is robust and wear-resistant, avoid directly striking the handle or lock body surface with hard objects to prevent damage to the decorative surface or displacement of internal precision parts.
After-sales technical support: If you encounter any technical problems during use or need to replace damaged parts within the warranty period, you can contact the company's long-term technical support team at any time for professional online guidance or on-site assistance.
