However, the layer of adhesive in the picture reached a thickness of up to one centimetre, which ultimately took the entire unit out of operation. And yet it would be enough to thoroughly clean the machine once a year. It is necessary to observe the maintenance intervals, especially with such specific solutions where the necessity of maintenance can already be expected in advance. You are saving your own costs.
