Hello, the pages of Atera are hardly about scrap level, if you don’t want to buy a new product, but need information about an already bought product… Unfortunately I found nothing else. I bought from Atera the and the , both were used without instructions, and with both I can’t cope… If someone could tell me where the two manuals are? Or else can give these 4 infos? For different Certo and Cargo models I have a manual for different Certo and Cargo models. and, but the models in it are probably newer, they have a different fixing system. Although mine has a “420” in the type designation, it corresponds to those in my PDF manual of Certo 410 (and not the Certo 420). thank you!
