5 Operation
Connecting hydraulic lines between machine and attachment
1. Pick up the attachment and safely lock it
– see "Attachments" on page 5-48.
2. Release the pressure in the hydraulic lines
– see "Pressure relief – plug couplings" on page 5-33.
3. Clean the hydraulic plug-and-socket connections.
4. Take the protective caps off the connections.
5. Couple the flexible lines.
To do this, with the Kramer quickhitch, the flexible lines A+B from the
3rd control circuit are connected to the plug couplings C+D of the
attachment.
With other quickhitches, flexible lines from the attachments are
connected to the plug couplings on the machine (e.g., with SKID
STEER attachments to the plug couplings A + B of the FASTER block)
– see "Hydraulic control circuits/plug couplings (overview)" on
page 5-34.
6. Check whether the hydraulic connections are engaged correctly. To do
this, pull on the hydraulic hoses.
➥ The hydraulic connections must not be released as you do so.
7. Close exposed connections with protective caps.
8. Check that the hydraulic system of the attachment and the hydraulic
connections are free of leaks. To do this, carefully move the
attachment.
9. Check the attachment for correct function and response direction:
