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).
Standard position:
with tractors with an open
hydraulic system
• e.g. a standard tractor with a gear pump.
- The position of the slotted screw (7) is set in the factory. The
slotted screw (7) must be screwed out to the point where the
screw head is level with the
surface (6) of the hydraulic
block.
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!

, fuse 16A (11).
• Power for the trailer is supplied via socket "54g" (+pole) and
"31" (-pole).
This modification is to be carried out only by specialized
workshops.
• Don’t connect directly to ignition.
• Don’t connect directly to battery (danger of fire and/or
