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 "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.
Standard position:
with tractors with an open hydraulic system
• e. g. standard tractors with gear pump.
- The standard basic adjustment on the shut-off valve applies for
these tractor types (position A). 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).
