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 system
See Fig. 13.
• Turn the knob of the pressure relief tool counterclockwise to make room for the coupler.
• Press the pressure relief tool on to the coupler of the hose or tool and screw the tool and the coupler
together.
• Wrap a cloth around the pressure relief tool, leave the knob free to operate.
WARNING
Make sure the cloth covers the oil openings, because a cloud of oil may appear without a
cloth.
• Turn the knob clockwise to release the pressure. Some oil will be released.
• Turn the knob counterclockwise and remove the pressure relief tool from the coupler.
