Hi, I have a summa D60R and the clamp that holds the blade in place has cracked. I have tried glueing it but refuses to hold the two pieces together. I have been in touch with the dealer here in the UK and they say its not worth repairing as it will cost over £700 to fix it, £400 for the part and £300 for summa to install it, seems a shame as its a cracking piece of equipment.
