To increase the pressure on a Renner Kompressoren RS-B, you would need to adjust the pressure switch settings. However, the manual warns that the pressure switch is pre-set at the factory for the specific machine configuration. Changing these settings without prior consultation with RENNER Kompressoren GmbH can negatively affect the service life of the system and void the legal warranty. Therefore, pressure adjustments should only be made after approval from the manufacturer.
