Maintenance
The bed lift system requires very little maintenance. The chains are pre-lubricated and nickel-plated to
prevent corrosion. All bearings are sealed and all parts are either plated or finished with a durable powder-
coat finish.
The only required maintenance involves keeping the mechanisms clean and free of debris. When cleaning
the trailer after use, inspect the vertical trolley channels for dirt or debris and clean as necessary. After
cleaning, a light application of dry silicone spray on the inner sides of the trolley channels will improve
performance and reduce noise and required amperage draw.
