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).
Power supply
• Power (8) 12V is supplied via relay (9) connected to the
ignition (10).
• Lead diameter 2,5 mm
2
, 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 (danger of fire and/or
damage of electrical equipment).
Establishing electric connection
- After completing above mentionnned work connect 7-pole
plug from trailer with socket.
- Check lights.
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,
- Close the shut-off valve (position B).
- Dismount lever (7) and fit onto the shut-off valve (11).
