Usable with some reworking

The delivery was accustomed quickly. When unpacking first noticed that the bolt described in the assembly instructions for locking the prestressed torsion spring was not included with the delivery (- 1 star). This problem I solved by I of the metal pin supplied as a clamping aid (equal diameter) sawed 5 mm around him to use as a replacement, which is also thanks to the bias of spring no problems with respect. Falling out of the pen moved to itself. Secondly, I found out that the non-lubricated rotary joint was so stiff that I had a great desire to return the whole thing again (- 1 star). Ultimately, the joint with silicone grease and lots of rotational movements was to distribute the fat still so smoothly that I have ventured an assembly. This was then easily (detailed assembly instructions are enclosed) and the door closer does its work just as I had imagined.
