Set-up and start-up 8.
7.3 Direct connection
The hydraulic hoses are screw-connected to the connecting block of the hydraulic unit.
Screw-in sleeves or adapters are mounted in the valve block. The hoses are secured directly
onto these screw-in sleeves or adapters by means of union nuts. To do so, you must first
remove the dust protection caps or locking screws and the steel balls underneath, then fit
the corresponding hydraulic hose and use the union nut of the hose to screw it firmly to the
screw-in sleeve or adapter. Please observe the torque of 35 Nm.
CAUTION!
Before commissioning the 620, the locking screw of the hydraulic fluid reservoir
must be replaced by the supplied filling screw with venting function. The locking
screw only serves the purpose of securing the hydraulic reservoir during
transportation and is to be stored in line with accepted principles.
REMARK:
In order to be able to mount the hoses directly onto the connecting block, adapters
or connection nipples have to be screwed into the valve block beforehand.
CAUTION!
Always connect the return hose first and then the supply hose!
