connections
Hydraulic connection at zero pressure only
Only connect hydraulic tubes to the tractor hydraulic system if the trac-
tor and implement hydraulic system is depressurised. A pressurised
hydraulic system can trigger unforeseen movements on the imple-
ment.
Avoid oil mixtures
If the implement is used on different tractors, a non-allowed oil mixture
may occur. Non-allowed oil mixtures can destroy components on the
tractor.
Check tubes and couplings
Check all hydraulic hoses for damage before connecting them. Check
all hydraulic couplings for firm seating after connecting them. Defec-
tive hydraulic tubes or poorly seated hydraulic couplings can trigger
unforeseen movements on the implement and cause accidents.
Secure the control devices
In transport position, secure the control devices on the tractor against
unintended actuation and lock if possible. Unintended actuation of the
control device can trigger unforeseen movements on the implement
and cause accidents.
Check the routing of the hydraulic hoses
The hydraulic hoses must not be jammed or strained. Ensure that
there is sufficient free space. Torn off or jammed hydraulic hoses lead
to uncontrollable movements of the implement and can cause serious
damage and injuries.
Hydraulic couplings
Check hose routing
Check routing of the hoses. The hoses must not scour nor hang down.
Cut lines or scouring can cause unpredictable movements of the im-
plement.

> Set the tractor hydraulics to “free float”.
> Connect the implement's hydraulic coupling to two connections of
the double-acting control device.
