5.4 Relief the pressure in unconnected hoses and tools
5.4.1 General
Temperature differences can cause overpressure in unconnected hoses and tools. This overpressure

overpressure. This accessory is available for both the CORE™ system and the dual-hose system and is
supplied with every pump as a standard.
NOTICE
We recommend to keep more than one of these tools on hand.
