HYDRAULIC OUTER CIRCUIT

Hydraulic outer circuit delivers the pres-
sure oil into hydraulic
connected to hydraulic outer outlets
equipped with quick-couplers. Quick-
coupler sockets have inner diameter
12,5 mm and correspond to the ISO
international recommendation.

Hydraulic outer
equipped with three quick-couplers lo-
cated on quick-coupler panel. Quick-
couplers No "1" and No "2" are alternati-
vely pressurized. The third quick-coupler
No "0" is connected directly with diffe-
rential case space and is intended for
turning of the oil from hydraulic imple-
ments (for example from rotary hydro-
motors etc.).
Attached implements using the oil from
hydraulic outer circuit must be filled with
the same kind of oil as recommended for
tractor transmission.
MAX.
FROM OUTER CIRCUIT
Max. 20 litters of oil can be temporarily
supplied from outer outlets for work of
attached implements. At bigger supply of
oil the hydraulic pump might draw in the
air and the pump could be damaged.
In case the oil level dropped after dis-
connecting implement caused by perma-
nent supply of oil from tractor into hydra-
ulic circuit of implement it ´s necessary to
add the missing quantity of oil.
