FILTER CLEANING
Manual Filter Cleaning When the filters reach saturation point, filter cleaning warning appears on the panel. Carry out the filter cleaning process within 2-3 minutes of a clean and dry compressed air hose with a pressure of 5-6 bar as shown in the picture below. Filter elements are cleaned from coarse dirt, this process extends the life of the filter element. If you have a model with two filters, do the same for the other air connection. Filter elements are cleaned of coarse dirt

Automatic Filter Cleaning
When the filters reach the saturation point, a filter cleaning warning appears on the panel and the cleaning is automatically activated. It performs cleaning for the set time of 1 minute. The cycle continues until the alarm is deactivated.
For filter cleaning, use a clean and dry compressed air of 5-6 bars.
In addition, every time the machine is turned off, it performs post cleaning. As the filter fullness warning system becomes more frequent and cleaning is not sufficient, the filter should be changed.
