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 () 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!
with tractors with a
closed hydraulic system
• JOhn-DEErE, FOrD Serie 0 SLE
CASE-mAGnUm, CASE-mAXXUm
Before coupling, the slotted screw (7)
on the hydraulic block is to be screwed
completely in.
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 "1"
(-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
damage of electrical equipment).
Establishing electric connection
- After completing above mentionnned work connect 7-pole plug
from trailer with socket.
- Check lights.
