5.3. Hydraulic System Maintenance and Use
Caution: The risk of infection caused by hydraulic oil ejecting under high pressure that penetrates the skin.
•
Work with the hydraulic system should be carried out in a specialist workshop.
•
Completely depressurize the hydraulic system before starting any work.
•
Use appropriate tools to detect leaks.
•
Never stop oil leakage with your hands or fingers.
•
Liquid ejecting under high pressure (hydraulic oil) may penetrate the skin and cause serious injury.
•
In the case of injuries caused by hydraulic oil, consult a physician immediately. The risk of infection!
•
When connecting the hydraulic hoses of the machine with the tractor hydraulic system, make sure that
the hydraulic systems of the tractor and machine are not under pressure.
•
Check the correctness of connecting the hydraulic hoses.
•
Regularly check that the hydraulic hoses, connectors and sockets are in good condition and clean.
•
Have the hydraulic hoses inspected by a specialist at least once a year, in order to ensure they are in
good condition.
•
Damaged or worn hydraulic hoses must be replaced with new ones.
•
Use only original hydraulic hoses.
•
The service life of hydraulic hoses must not exceed 6 years, including the storage time of the machine,
for a maximum of two years. Even in the case of proper storage and observance of the instructions for
use, hoses, hydraulic hoses and connections are getting old, which is completely normal, hence the
limitation of their storage and working time. However, the time of use may depend on empirical factors,
in particular taking into account the potential risks. With regard to hoses and thermoplastic hydraulic
hoses, other reference parameters may also be taken into account.
•
Disposal of used oils must comply with applicable regulations. In the event of a problem, please contact
your oil dealer.
•
Store hydraulic oils out of the reach of children.
•
Be careful not to contaminate the ground or water with hydraulic oil!
After the first 10 hours of operation, and then, after every 50 hours of operation
1. Check all components of the hydraulic system for tightness.
2. If necessary, tighten the connectors.
Before each start-up
1. Visually inspect the condition of the hydraulic hoses for any defects.
2. Eliminate points of friction of pipes and hoses.
3. Damaged or worn hydraulic hoses must be replaced immediately.
Inspection criteria for hydraulic hoses.
For your own safety, observe the following review criteria:
Replace the hydraulic hoses if, during the review, you find one of the following:
•
Damage to the outer layer up to the reinforcement (e.g. abrasion areas, cracks, crevices, scratches, etc.).
