The inability to disconnect a flat face coupler may be due to excessive pressure within the hydraulic line. This can occur if the machine was not properly shut down, leading to a buildup of hydraulic pressure that makes it difficult to disconnect the coupler. Sources: 1. "Hydraulic Quick Couplings" - Parker Hannifin (https://www.parker.com/literature/Qui...). This information is found on page 6 under the section titled "Safety Guide for Selecting and Using Hydraulic Quick Connect Couplings" where it discusses the dangers of disconnecting under pressure. 2. "Hydraulic Quick Coupling Failures and How to Address Them" - Hydraulics & Pneumatics (https://www.hydraulicspneumatics.com/...). The article mentions under the section "Unable to Connect or Disconnect" that excessive pressure can make it difficult to disconnect the coupler.
