The operating instructions in German and English and can be printed larger. The wall mount is working hard and very solid. While a built-in level on the part which is to be screwed on the wall is, I have used my own spirit level for the assembly. First I attached the two tabs on my Samsung LED 46Zoll, unfortunately, the screws were a bit too long but with a washer no problem. I recommend here especially to watch because the screw is too long and it is attempted with violence they can be screwed into the threaded bushes easily damage the TV. So here either the screws with a saw or cut Flex (deburring remember), the hardware store get shorter screws or mounted with washers. There are lots of screws in so that the assembly is to be made easily. Depending on the wall man should get the matching Dübbel. Have attached to the wall bracket with my Fischerdübbel SX 8x50 and 6mm carriage bolts. The television is now (two man) simply to the wall mount hooked up. They are secured with 2 screws which are screwed from below into the wall mount, this best on the TV something so tilt up enough space for the hand and the screwdriver as is. If the Dübbel hold, then the rest holds bombproof also specifically. Already have mounted two of these holders and am very happy with it.
