FIRST CONNECTION TO THE TRACTOR
HYDRAULIC CONNECTION
VERY IMPORTANT: Before making the hydraulic
connection to the tractor, check the oil condition. If it
is contaminated, change it, otherwise the hydraulic
block and remaining hydraulic components of your
machine could be damaged.
The machine needs 1 double hydraulic circuit, to
activate the hydraulic block, in order to do this:
- Connect the pressure line (1) and the oil return tube (2) (the
tube with the bigger diameter is the oil return tube), the
command lever of the line on the tractor has to be positioned so
that the hose of the greatest diameter is making the return to
the tank.
Note:
If the oil heats up during functioning, and the tractor only has a
constant flow rate pump, then it should be linked to a
simple effect line (see image).
- Connect the pressure hose (1) to the single action control unit.
Connect the oil return hose (2) (with the bigger diameter) to a
direct connection to the oil deposit.
If the tractor allows it, reduce the oil flow rate
REGULATION OF THE HYDRAULIC BLOCK:
Pos. "H±10 mm" to closed hydraulic system
Tractor with variable flow rate pump
Before making the connection, the LS screw on the hydraulic
block should be adjusted to the quota of ±10 mm (totally fasten
LS)
Pos. "H±17 mm" to open hydraulic system
Tractor with constant flow rate pump
The position of the LS screw on the hydraulic block should be
adjusted to a quota of ± 17 mm. (totally unfasten LS)- (factory
configuration).
Warning!
If this is not done, the overload valve on the hydraulic system of
the tractor is continuously in use and an excessive heating of the
oil will take place.
If the tractor has a closed hydraulic system and the hydraulic block
is in the position "A=17" then the hydraulic oil will heat up
(especially due to the constant pumping of the maximum quantity
of oil).
Solution: Place the tuner LS on pos. “A=10 mm”
LS = Load detection
