HYDRAULIC OUTER CIRCUIT
Hydraulic outer circuit delivers the pres-
sure oil into hydraulic implements con-
nected to hydraulic outer outlets equip-
ped with quick-couplers. Quick-coupler
sockets rear (A) and front (B) have
inner diameter 12,5 mm and they cor-
respond to the international standard
ISO 5675.
MAX. OIL CAPACITY SUPPLIED FROM HYDRAULIC OUTER OUTLETS
Max. 12 litters of oil can be temporarily supplied from outer outlets for filling
the hydraulic cylinders of attached implements. This is considered with
standard oil level in transmission i.e. up to upper mark of oil dipstick and if
the tractor does not work in hilly conditions. For increasing the supplied oil
capacity it is possible to add up to 15 l of oil into transmission.
When bigger supply of oil the transmission oil level can drop so low that the
pump of hydraulic and transmission might draw in the air. In this case not
only the pump and also the Hi-
Lo or PTO clutch could be damaged
It is necessary to pay attention when disconnecting and connecting the hydraulic
quick-couplers because of residual pressure being in female or eventually male of
quick-couplers. Taking ecology into consideration remove the spilt oil by a textile
cloth after any disattaching the quick-couplers.
