Clearly, the covering must be lubricated again the scissors away and. Previously I had the teeth individually cleaned with acetone and then lubricated with machine oil. This is time-consuming, I cut myself - but it helps.
Now I have tried it with care spray. The spray absorbs in the debris - not too little spray! Leave for a few minutes. Scissor switch on ... and ... the hedge trimmer is in fact again smoother. The deposits but are not removed completely, but only partially. I know not whether the spray should do this. There is nothing on the package or the Bosch website, why and how the spray is to be applied. I would have expected that the spray also the covering removed completely.
On another site I found a data sheet for chemical analysis of the spray. From this it follows that the components are more readily biodegradable, but you should avoid contact with the skin and inhalation. Therefore, use the spray outdoors. Although a spray comes easy in all the cracks - but unfortunately also a lot bib. Therefore, I put the hedge trimmer on a table, which I covered with newspaper. Aerosol sprays everything goes what goes wrong in the newspaper that I can then throw away what is hopefully more environmentally friendly, as the action easy to carry out in the open and let the rest Spray spray else where.
Conclusion, who wants to purify his hedge trimmer properly, has to resort too acetone or the like. Whether the spray is better than WD40, machine oil & Co I can not say. I miss product information from Bosch, which describe the field of application and the benefits of sprays clear, inter alia, regarding cleaning and lubrication. However: The Einsprayen goes fast and the gap is purring again, but I bought it. After I was completely finished with the hedge, I have the deposits still removed with acetone, so the scissors for the next season is clean and lubricated.
