Standard position:
with an open hydraulic system
• e.g. A standard tractor with a gear pump.
- The standard basic setting for the shut-off valve (position A)
applies to this type. In this position the shut-off valve is open.
Tip!
If the tractor has a closed hydraulic system and the unit is operating
in this position, then the hydraulic oil will heat up (particularly due
to the constant pumping of the maximum amount of oil).
Remedy:
Modify the system on the trailer or decrease the amount
of oil being pumped at the tractor as written below.
Take care
!
with tractors with a closed hydraulic
system
• JOHN-DEERE, FORD Serie 40 SLE
CASE-MAGNUM, CASE-MAXXUM,

hydraulic connection
Single-action control unit
Should the tractor only have a single-action servo-valve, then it
is absolutely necessary to have an oil-return pipe (T) fitted by a
specialist.
- Connect pressure hose (1) to the single-action control unit. Couple
the oil-return hose (2) (with the greater diameter) to the tractor’s
oil-return system.
Double-action control unit
- Connect pressure line (1) and oil-return pipe (2) (pipe with the
greater diameter is the oil-return pipe).
Note:
If oil should become warm during operation then a
single-action control unit should be connected (see
above).
