KTR-N 445102 EN ® KTR-STOP M-xxx B-xx-xx Sheet: 6 of 22 Operating/Assembly instructions Edition: Storage, transport and packaging 3.1 Storage The brake is delivered in preserved condition and can be stored in a closed, dry place during 12 months. With favourable storage conditions its properties remain unchanged for up to 12 months. If the brake is stored over a longer period exceeding 12 months as well as after each transport the corrosion pro- tection needs to be renewed and the brake has to be applied over the full braking distance in order to prevent the gaskets from sticking together. -
