5.1.2 Quick-lock couplers
The tool is equipped with a male and a female Quick-lock coupler. Quick-lock couplers are pushed into
each other and then lock.
In case of duo hoses, the supply hose and the return hose are bundled together with ties. Each end of
the hose has a female and male coupler.
If you want to connect or disconnect a tool and/or a hose, you must first set the pressure relief valve
handle on the pump to the pressure relief position. After connecting the hose(s) and the tool you must
set the pressure relief valve handle to the operation position so you can use the tool.
