The dt. Manual includes 6 pages, of which four (!) Pages warnings and safety instructions. Excerpt:
1. Wear ear protection (NB. Important, because the unit is in operation very, very loud and still does not solve any screws.)
2. Wear a dust mask. When working with wood (!!!) ... can develop harmful dust. Material containing asbestos must not going to be processed! (Check Note. So previously if not probably. Nor old, asbestos-containing brake pads are installed.)
3. Wear safety goggles. Generated during working or sparks out of the machine kicking Splitter (!!!), chips and dust can cause loss of face. (NB. At least here it becomes clear that quality of manufacturer / importer attaches to this wrench.
Conclusion: device so again packed and sent back. At Amazon, there are elsewhere an identical device about 20 cheaper, which is still too expensive.
For me incomprehensible that you offer such a bad design at all.
