After so roughly estimated 25 years old blind machine had given up and a new part was needed. After measuring the tensile forces on the roller shutter, I have decided for the Rademacher shutters drive UP Comfort, which also corresponds to the current product on the website Rademacher. Except for one small thing the exchange of Rolladenantirebs went without a hitch. The instructions describe the installation in great detail considering all precautions. In contrast to the previous blind machine of quiet running and soft start / soft braking convinced. The additional programming possibilities are up to date and actually default.
A star deduction there for some completely unnecessary vulnerabilities:
1.The grottenschlechte original packaging, fortunately I have the Inner Carton pulled over a table, because the part when pulling out just fell out.
2. The guide was rolled up and had to be smoothed before.
3. Instructions and design of the grid connection start from a mobile power supply, with a permanent connection in Gurtwicklerkasten it's been quite a fumbling to bend the pipes accordingly, and attach the cover on the power connector.
