Bosch Blue possibly defective drilling chuck?

Hello guys, I have a question for the tool experts here. Got my Bosch GSB 18V-55 today. Is a used tool that is ahead. I noticed the following: If I want to drive the drill lining completely open and close again there are unpleasant scratching noises until the baking lining is completely attached, is that normal? If I don’t drive the drill lining back completely I don’t have the noise. If I want to close it completely and open it, then there is a jerk that in my opinion is normal, and then it can be driven back fluidly. Problem, in my opinion, only exists if it has been completely driven back. If I then want to drive again by hand, for example, then there is no such jerk and it scratches inside until it is closed again. Then I can again silently open and do. I just can not completely make up, this certain point does not exceed. I recently had an absolutely new Gsr 18v-55. My uncle got it because he made me an offer that I couldn’t refuse. I bought the current gsb 18v-55 from classified ads via Paypal and services. I wanted to ask you first about your opinion and tomorrow someone might ask at the construction market to show the device. If it is only the drilling feed I would possibly buy it. If more in the bad, then it goes back. I thank you in advance and I did not make such noises at all. Have a nice evening.
