The user manual will not help you with this because the Arcitec models were designed so that the cutters could NOT be removed to be cleaned. This is a major disadvantage with the Arcitec models as you can not disassemble the heads to thoroughly clean them. This causes you to have to replace them more frequently. You can try running the shaver head in a dish of rubbing alcohol to try to loosen the build-up and rinse it out but that's about all you can do. If you need to replace them, you will find at shaveroutlet.com. See link below
