[. . . ] We recommend that you shave before washing, as the skin tends to be slightly swollen after washing. To maintain 100% shaving performance, replace your foil and cutter block at least every 18 months or when worn. Press the release buttons, take off the shaver foil (d) and gently tap it out on a flat surface (e). About every four weeks, clean the cutter block with Braun cleaning agents (g). If you have a very dry skin and you notice a reduced operation time of the shaver, you should put a drop of light machine oil onto the InterFace trimmer and shaver foil (g). To maintain 100% shaving performance, replace your foil and cutter block at least every 18 months or when worn. Change both parts at the same time for a closer shave with less skin irritation. Replace the new shaver foil in the right direction until it locks in place. In order to optimise the capacity and life of the batteries, the shaver should be fully discharged through regular use every 6 months approximately. Do not expose the shaver to temperatures of more than 50 °C for long periods of time. In the interest of protecting the environment, please do not dispose of the product in the household waste at the end of its useful life. Disposal can take place at a Braun Service Centre or at appropriate collection points provided in your country.
