2.16.2 Hydraulic system
•
The hydraulic system is under a high pressure.
•
Ensure that the hydraulic hose lines are connected correctly.
•
When connecting the hydraulic hose lines, ensure that the hy-
draulic system is unpressurised on both the machine and tractor
sides.
•
The blocking of control elements on the tractor that serve the
direct execution of hydraulic or electrical movements of compo-
nents, e.g. folding, swivelling and sliding operations, is prohibit-
ed. The movement must stop automatically when the relevant
control element is released. This does not apply if the equipment
movements
o
are continuous or
o
are automatically locked or
o
necessarily require an open centre or pressure position to
operate correctly
•
Before working on the hydraulic system
o
Lower the machine
o
Depressurise the hydraulic system
o
Switch off the tractor engine
o
Apply the parking brake
o
Take out the ignition key
•
Have the hydraulic hose line checked at least once a year by a
specialist for proper functioning.
•
Replace hydraulic hose lines that are damaged or are showing
signs of ageing! Only use genuine
hydraulic
hose lines!
•
Hydraulic hose lines should not be used for more than six years,
including a maximum storage time of two years (if applicable).
Hoses and hose connections are subject to a natural ageing
process even if they are stored properly and the permissible
loading is applied during use which means their storage time and
time of use is limited. A different period of use can be defined
depending on empirical values and taking in particular the poten-
tial danger into account. Other guide numbers may apply for
hoses and hose lines made of thermoplastics.
•
Never attempt to plug leaks in hydraulic lines using your hand or
fingers.
Escaping high pressure fluid (hydraulic fluid) may pass through
the skin and ingress into the body, causing serious injuries!
If you are injured by hydraulic fluid, contact a doctor immediately.
Danger of infection!
•
When searching for leakage points, use suitable aids, to avoid
the serious risk of infection.
