In order to ensure proper operation of the air dryer, check the air reservoirs for condensed water.
1. Check the air reservoirs for condensed water by pulling the drain valve rings.
2. If a higher than normal amount of water comes out repeatedly, replace the air dryer cartridge. Contact an authorized TATRA service.
If water occurs in the air reservoir, check the condition of the dryering cartridge.
It is also necessary to check the air system for leaks and remove any leaks immediately as they prolong the time during that the compressor fills the system and have unfavorable effect upon the air dryer function.
If oil is detected in the driing cartridge, replace the cartridge.
