•
Only use genuine AGRISEM hydraulic hoses.
•
Hydraulic hoses must not be used for more than six years, including a possible storage time of
two years maximum. Even under appropriate storage and usage conditions in line with
permissible stresses, it is completely normal for hoses and connectors to age, which is why
they have a limited storage time and service life. Nevertheless, the duration of use can be
established in line with empirical values, in particular taking potential risks into account. Other
reference values can be taken into consideration for thermoplastic hoses and pipes.
•
Dispose of used oil in accordance with current regulations. If this poses a problem, contact
your oil supplier.
•
Keep hydraulic oil out of reach of children.
•
Ensure that you do not contaminate the soil or water with hydraulic oil.
After 10 hours of service, and then every 50 hours of service
1. Check that all of the hydraulic circuit's components are sealed.
2. If necessary, tighten screwed connectors.
Before each start-up
1. Visually check the hydraulic hoses for faults.
2. Remove any friction points on hydraulic hoses and tubes.
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.
