NOTE
When connecting the hoses to the tractor hy-
draulics you must make sure that both the hy-
draulics on tractor and trailer are pressureless!
NOTE
The hydraulic cylinders must be filled again
with hydraulic oil after carrying out installation
work on the hydraulic system. This is done by
selecting all hydraulic functions several times.
Hydraulic cylinders must extend and retract
without jerking.
¾
Danger zones must be blocked off during
commissioning.
¾
When performing installation work, raised
machine parts must be lowered completely,
moved to a safe position or secured at the
particular level by suitable means.
Even if properly stored and under permissible
stress, hoses and hose connections are subject
to natural ageing. This limits their shelf life and
their utilization period.
Deviating from this, the utilization period can
also be determined on the basis of empirical
values, particularly under due consideration of
the endangering potential. For hoses and hose
lines made of thermoplastics other guide values
may be decisive.
The utilization period of hydraulic hoses
should not exceed six years, including a
possible storage time of maximum two years.
Depending on the conditions of use (e.g. weath-
er influences) or in case of higher strains on the
machine the hoses may need to be replaced
earlier.
¾
Dispose of old oil environmentally. Strictly
adhere to the corresponding country-specific
regulations.
¾
Keep hydraulic oil out of the reach of children!
¾
Make sure that no hydraulic oil enters into the
ground or into water!
¾
In addition follow the country specific regula -
tions and directives.
NOTE
Additional specifications of the hydraulic system
(circuit diagrams, etc.) can be obtained from the
HORSCH service department.
Inspection criteria for hydraulic
hoses
NOTE
The following inspection criteria must be ob-
served in the interest of your own safety and to
reduce environmental damages!
Replace hoses, if these fulfil at least one
criterion from the following list:
¾
Damage to the outer layer to the ply (e.g.
chafing, cuts, cracks).
¾
Embrittlement of the outer layer (formation of
cracks in the hose material).
¾
Deformations, which do not correspond with
the natural shape of the hose. Both in pres-
sureless and pressurized condition or in case
of bending (e.g. layer separation, formation of
blisters, squeezing, buckling).
¾
Leakages.
¾
Failure to comply with installation require-
ments.
¾
The max. utilization period of 6 years has
expired.
The date of manufacture on the hydraulic hose
fitting plus 6 years is decisive. If the fitting is
marked with the manufacturing date “2014”,
the utilization period ends in January 2020.
NOTE
Leaking hoses / pipes and connecting pieces
are frequently the result of:
¾
missing O-rings or seals
¾
damaged or poorly fitted O-rings
¾
brittle or deformed O-rings or seals
¾
foreign objects
¾
loose hose clamps
