   NOTICE! Housing damage caused by incorrect aids and cleaning

   1. Clean the surface with a dry microfiber cloth.

      Be careful not to detach the symbol stickers. The adhesive foil is especially sensitive to friction and harsh cleaning agents.

   2. If some dirt cannot be removed this way, moisten the cloth. Use a pH neutral cleaning agent if necessary.

      • Avoid exposing the surface to alkaline or acidic substances. Metallic powder coating materials are especially sensitive.

      • If a special cleaning agent is used to remove certain impurities, check the suitability of the agent in advance at a hidden location on the painted part.
