Checking Hydraulic Hoses
Hydraulic hoses are subjected to high stress. They must be checked regularly
and be immediately replaced if damaged.
Hydraulic hoses are subject to an ageing process. They may be used for a max-
imum of 6 years, including storage time of maximum 2 years.
Regularly check the hydraulic hoses, at the latest before the start of the
spreading season, with a visual inspection for wear.
Replace the hydraulic hoses when detecting the following damage:
-
Damage to the outer layer through to the inlay,
-
Embrittlement of the outer layer (formation of cracks),
-
Deformation of the hose
-
Sliding of the hose out of the hose fitting,
-
Damage to the hose fitting,
-
Reduced strength and function of the hose fitting as a result of corrosion.
Before the start of the spreading season, check the age of all the hydraulic
hoses. Replace the hydraulic hoses once the storage and use duration has
elapsed.
9.12.2
Replacing Hydraulic Hoses
Preparation:
Ensure that the hydraulic system is
depressurized
and
has cooled down
.
Provide a collection container for escaping hydraulic oil under the separation
points.
Provide suitable caps, to prevent the hydraulic oil from escaping from hoses
which do not have to be replaced.
Prepare suitable tools.
Wear protective gloves and goggles.
Ensure that the new hydraulic hose corresponds to the model of the hose to
be replaced. Pay particular attention to the correct pressure range and the
hose length.
NOTICE
The manufacturing date of the hose is given on one of the hose fittings as the
month and year (e.g. 09/4).
NOTICE
In particular, note the different maximum pressure ratings of replacement hoses.
