Service Bulletin/Repair Instructions
The Polar MyLift system is an optional component that will automatically lift one or more axles when a trailer is unloaded, and deploy all axles as the trailer loads. Some MyLift systems have been observed to contain a pitted pressure switch contact, causing the system not to function as designed. Reliable failure of the component has not been confirmed, and full manual control of the axle lift functions remains intact. However, Polar?s commitment to reliable products leads us to trade out existing MyLift assemblies with an upgraded version.
