Today, exactly what happened to a friend of mine, the pen of the rotating hammerwork in the impact screwdriver is broken, with a somewhat tough spray when changing wheels. With a very well-known quality brand device. But I was able to help out with my somewhat pimped, outdated ALDI device. He beat the fixed screw out like nothing, was about 3 sec at the hit, felt that is for a long time. Now, of course, a new impact mechanism is needed, but the spare parts are more expensive, since looked One was found, without a battery and charger for almost 90,-€, that spare part would have cost even a little more, so first of all ordered, if the impact unit does not fit, the battery and the charger is also reordered, so that you have a complete and usable tool again.
