4.9 HYDRAULIC
CONNECTION.
The hydraulic hoses between machine and tractor are equipped with 1/2" ISO male quick-
couplers. Discharge the oil pressure before you connect the oil hoses. The tractors' hydraulic
lever must be lock open when running. To make sure that the bale wrapper works properly, the
tractors' oil pressure has to be at least 180bar. The oil flow should be 15 - 25 liters per minute.
The return pressure on the return must be as low as possible, and not exceed 10 bar. This
should be measured with a gauge. It is recommended to use one single-acting hydraulic outlet
and arrange a free return circuit to the oil tank. If you are unsure of what oil pressure the tractor
gives, or what oil pressure the bale wrapper receives, please contact your machinery dealer.
Generally all tractors have got some counter-pressure in their hydraulic return systems. Some
tractors have more than others.
Hose with red cap shall be connected to pressure, (P), and hose with blue cap to the
return. (T).
(See fig. 4-11).

OPEN and CLOSED CENTER and LS HYDRAULIC SYSTEM.
The 1510/14 EH hydraulic system can be set up for tractors with open or closed
center hydraulics
Open Centre Hydraulics
Most tractors have a hydraulic system that gives a continuous output which
flows through the valve on the machine and back to tank when no function is
operating. (Open center).
TANCO AUTOWRAP 1510/14 EH is set-up for open centre on leaving the
factory.
Close Centre Hydraulics
Some tractors, (like John Deere), have a hydraulic system that require the
valve on the machine to allow no flow when no function is operating (Closed
center). The hydraulic valve can easily be configured to operate in this way.
Simply push and twist the manual override on the master valve and close fully
valve V2. (see fig 4.12)
