Condensate (condensed water) deposits in the brake system air reservoirs during the operation, which must be periodically discharged.
In order to ensure proper operation of the air dryer, check theair 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 repair shop.
The full working pressure must be in the braking system during draining.
