3. Replace damaged or worn hydraulic hoses immediately.
Inspection criteria for hydraulic hoses.
For your own safety, comply with the following inspection criteria.
Replace the hydraulic hoses if you notice any of the following when examining them:
•
Deterioration of the outer layer down to the lining (e.g. friction points, cuts, splits).
•
Embrittlement of the outer layer (formation of cracks on the outer layer).
•
Distortions which do not correspond to the natural shape of the hose or pipe, whether or not
they are under pressure or bent (e.g. separation of the layers, bulges, crushed areas,
bending).
•
Areas that are leaking.
•
Damaging or distortion of the end fitting (affecting its leaktightness). Slight superficial damage
does not warrant replacement.
•
Hose becoming detached from the end fitting.
•
Corroded end fitting leading to reduced solidity and function.
•
Non-compliance with mounting specifications.
•
Exceeding of the 6-year usage period. The following information is vital: the date of
manufacture of the hydraulic hose marked on the end fitting, to which you must add 6 years. If
the date of manufacture indicated on the connector is "2004" the usage period will end in
February 2010. See the "Marking of hydraulic hoses" section for further information.
Fitting and removing hydraulic hoses
When fitting and removing hydraulic hoses, the following instructions must be strictly adhered to:
•
Only use genuine AGRISEM hydraulic hoses.
•
Pay particular attention to cleanliness.
•
You should always fit hydraulic hoses so that in all operating conditions,
They are not subject to traction, apart from that caused by their own weight.
No short lengths are flattened.
There are no external mechanical stresses on the hydraulic hoses.
Avoid hoses rubbing against parts of the machine or against each other by arranging
and attaching them correctly. Protect hydraulic hoses with protective sheaths if
necessary. Cover parts with sharp edges.
The authorised bending radii must not be exceeded.
•
If hydraulic hoses are connected to moving parts, measure the length of the hose to ensure
that the total range of movement is no less than the smallest authorised bending radius and/or
that the hose is not subject to traction.
•
Attach hydraulic hoses at the places intended for this purpose. Avoid mountings that may
hinder the natural movement of the hose and modifications to its length.
•
Hydraulic hoses must not be painted.
Wear ring maintenance:
Some joints on AGRISEM tools have wear rings. These must be changed at the first sign of lateral
play.
Tyre maintenance:
The tyres must always be inflated to a pressure appropriate to their use. The pressure may need to be
changed when moving between the road and the field. The average pressure of all Flexi-Pack tyres is
2.5 bars.
