I bought production- lathe BERNARDO Profi 300 in Wiena into the KFZ-Meisterbetrieb Effingerrrgasse 31 shop.

When I put lathe in electricity the fuse burn out.On the PCB - DC MOTOR SPEED CONTROL I found forgotten metal pad, which cause the damage known as «short circuit» . The transistor(or voltage regulator) blown, as you can see on the picture( the transistor or voltage regulator is marked).The markings of the elements are intentionally removed. I need a label burning electronic elements for repairs controler.

Please, help me if you can, because my lathe doesn’t work.
