Sorry to hear that kstano83. You really are having problems with that machine aren't you? Must be a "Friday afternoon" or a "Monday morning" jobbie!
I understand that you're in Slovakia, so I don't think that Axi are being unreasonable - AFAIK, they don't have any branches or anything anywhere overseas, and probably their nearest dealer to you is in Germany (Dictum Tools in Munich). But in the little experience I've had with Axi, I've found them to be always as helpful as possible, and IME they seem to be a reputable company too, so I suggest you try the following:
1. Call a local sparky (one who has experience of machinery, not just domestics) and get him to find out exactly what the problem is. Get him to list the spares you need, (you HAVE still got the manual with all the spare parts itemised in it, haven't you?), together with a description of exactly what is wrong. ALSO get the sparky to give you an itemised bill, including detail of his working time with you, his travel time/call out fee, etc, together with the total you have to pay him. And all the above in English if he possibly can.
2. Contact Axi again with all the above details, and offer to E-mail them a copy of the above. Then see if you can "do a deal" with them. For example "You - Axi - supply the necessary spares FOC, and I'll pay the postage and import duty, etc, for them; plus you - Axi - split the cost of the sparky with me, 50/50". Or something similar.
They may or may not go for something like that, but the machine HAS got a fault, it IS still in Warranty, and when they accepted your order they knew you live in Slovakia, so there should be some room for "negotiation" on their side. After all under the terms of the Warranty you could - I THINK - just ask for your money back!
HTH, good luck, let us know what happens please.
