Overview<\/h2>\n\n\n\n

Proper maintenance of your tender lift system is essential to ensure long-term reliability, safe operation, and optimal performance. Marine environments expose lift systems to saltwater, dirt, and mechanical wear, making regular maintenance a critical part of ownership.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Materials and Durability<\/h2>\n\n\n\n

Presto Marine lift systems are manufactured using high-quality materials designed for harsh marine conditions, including:<\/p>\n\n\n\n

    \n
  • Duplex stainless steel<\/li>\n\n\n\n
  • 316 stainless steel<\/li>\n\n\n\n
  • Marine-grade 5083 aluminum (used in rail systems)<\/li>\n<\/ul>\n\n\n\n

    All components are treated with protective coatings to resist corrosion and wear.<\/p>\n\n\n\n

    Despite this, regular maintenance is still required due to continuous exposure to saltwater and environmental debris.<\/p>\n\n\n\n

    <\/p>\n\n\n\n

    After Every Use<\/h2>\n\n\n\n

    To maintain performance and prevent buildup, it is recommended to perform the following after each use:<\/p>\n\n\n\n

      \n
    • Flush the lift and rail system with fresh water<\/li>\n\n\n\n
    • Remove dirt, salt, and debris from all components<\/li>\n\n\n\n
    • Ensure rails are clean and free from obstructions<\/li>\n<\/ul>\n\n\n\n

      This routine helps prevent corrosion and ensures smooth operation.<\/p>\n\n\n\n

      Cleaning When Needed<\/h2>\n\n\n\n

      Depending on usage conditions, additional cleaning may be required:<\/p>\n\n\n\n

        \n
      • If the rail system contains sand, leaves, or debris \u2192 rinse thoroughly with fresh water<\/li>\n\n\n\n
      • Clean the lift using boat or car shampoo and water<\/li>\n\n\n\n
      • Avoid buildup that can affect moving components<\/li>\n<\/ul>\n\n\n\n

        Regular cleaning improves both performance and lifespan.<\/p>\n\n\n\n

        Annual Maintenance (Rail Systems)<\/h2>\n\n\n\n

        Rail-mounted lift systems require annual servicing<\/strong> to maintain proper functionality.<\/p>\n\n\n\n

        What Needs to Be Serviced<\/h3>\n\n\n\n

        Focus on the rail system running wheels and bearings<\/strong>:<\/p>\n\n\n\n

          \n
        • Each lifting unit includes 4 running wheels<\/li>\n\n\n\n
        • Bearings must be cleaned, inspected, and re-greased<\/li>\n<\/ul>\n\n\n\n

          Step-by-Step Service Process<\/h3>\n\n\n\n

          1. Remove the wheel assembly<\/strong><\/p>\n\n\n\n

            \n
          • Unscrew the locking bolt using a 4 mm Allen key<\/li>\n\n\n\n
          • Remove the running wheel and needle bearing<\/li>\n<\/ul>\n\n\n\n

            2. Clean components<\/strong><\/p>\n\n\n\n

              \n
            • Wash with warm water and mild soap<\/li>\n\n\n\n
            • Allow all parts to dry completely<\/li>\n<\/ul>\n\n\n\n

              3. Replace bearing (if needed)<\/strong><\/p>\n\n\n\n

                \n
              • Remove the old bearing using a suitable tool<\/li>\n\n\n\n
              • Install the new bearing securely<\/li>\n\n\n\n
              • Ensure the bearing does not rotate inside the wheel<\/li>\n<\/ul>\n\n\n\n

                4. Apply grease<\/strong><\/p>\n\n\n\n

                  \n
                • Use water-resistant grease (equivalent to SKF LGMT 2\/0.2)<\/li>\n\n\n\n
                • Fill bearings thoroughly<\/li>\n<\/ul>\n\n\n\n

                  5. Reassemble system<\/strong><\/p>\n\n\n\n

                    \n
                  • Reinstall all components<\/li>\n\n\n\n
                  • Apply grease during assembly<\/li>\n<\/ul>\n\n\n\n

                    6. Clean the rail system<\/strong><\/p>\n\n\n\n

                      \n
                    • Use a brush and water to remove dirt<\/li>\n\n\n\n
                    • Ensure smooth movement of wheels<\/li>\n<\/ul>\n\n\n\n

                      These steps ensure consistent performance and reduce mechanical wear.<\/p>\n\n\n\n

                      <\/p>\n\n\n\n

                      When the Lift Feels Heavy<\/h2>\n\n\n\n

                      If the lift becomes difficult to move along the rail system:<\/p>\n\n\n\n

                        \n
                      • Clean and service the rail system immediately<\/li>\n\n\n\n
                      • Inspect bearings and bushings<\/li>\n\n\n\n
                      • Replace worn components if necessary<\/li>\n<\/ul>\n\n\n\n

                        Heavy movement is often caused by dirt buildup or worn maintenance parts.<\/p>\n\n\n\n

                        Recommended Maintenance Kit<\/h2>\n\n\n\n

                        For ongoing maintenance, Presto Marine recommends using:<\/p>\n\n\n\n
