Relief the pressure in unconnected hoses or tools

5.4.1 General
Temperature differences can cause overpressure in unconnected hoses and tools. This overpressure
can make it impossible to connect the parts. You can use the pressure relief tool to remove this
overpressure. This accessory is available for all Holmatro hose systems and is supplied by default with
every pump.
Note
We recommend you keep more than one of these tools on hand.
5.4.2 High-Flow couplers

• Turn the knob of the pressure relief tool counterclockwise to make room for the coupler.
