The backrest angle adjustment mechanism in urban outdoor seats requires regular lubrication to maintain functionality and prevent wear. For typical public seating installations, a lubrication cycle of every 6-12 months is recommended, though frequency may vary based on usage intensity and environmental conditions.
The lubrication process involves applying a weather-resistant lubricant specifically designed for outdoor mechanisms. Silicon-based or lithium grease lubricants are most suitable as they resist water washout and temperature fluctuations. Before application, clean the mechanism thoroughly to remove dirt and old lubricant residue.
Regular maintenance ensures smooth adjustment operation, prevents corrosion, and extends the service life of public seating furniture. Municipalities and maintenance teams should incorporate this lubrication schedule into their routine urban furniture maintenance programs to ensure public comfort and safety.
