Open the drain valves for the air tanks.Note: Small amounts of moisture may be in the system due to internal condensation. Moisture may also be in the system if an air dryer is installed on a machine that has been operating without an air dryer. Several weeks may be required to completely remove the moisture from the system.
Check for moisture in the air tanks. Close the drain valves for the air tanks.
If there is moisture in the air tanks, replace the air dryer desiccant cartridge or rebuild the air dryer desiccant cartridge. Consult your Caterpillar dealer for information about replacing the desiccant cartridge and for instructions for rebuilding the desiccant cartridge.
