Hydraulic System - Hardi AEON CENTURA TWIN FORCE Instruction Book

Hydraulic System

The sprayer is supplied with hydraulic functions operating under a high pressure.
In case of malfunction, there is a risk that the hydraulic system may act inadvertently. This can lead to:
• Fatalities or serious injuries to persons or animals in the working area of the sprayer.
• Material damage to the sprayer when colliding with trees, vehicles or other objects in the working area of the sprayer.
Ensure that the hydraulic hose lines are connected correctly.
When connecting the hydraulic hose lines, ensure that the hydraulic system is depressurized on both the sprayer and tractor
sides.
The operator-controls in the tractor, used for hydraulic and electrical movements of components must stay unlocked, e.g. for
folding, swivelling and pushing movements. The movement must stop automatically when you release the appropriate
control. This does not apply to equipment movements that:
• Are continuous.
• Are automatically controlled.
• Require a floating position or pressed position to function.
Before working on the hydraulic system:
• Lower the spray boom to its lowest position or into the transport position.
• Turn off / depressurize the hydraulic system.
• Turn off the tractor engine.
• Engage the parking brake.
• Remove the ignition key.
Have the hydraulic hose lines checked at least once during a calender year by an expert to ensure that they are in safe working
order.
Replace the hydraulic hose lines if they are damaged or worn, which is when:
• It is leaking.
• Reinforcement material inside the hose is visible due to cracks in the outer layers.
Only use genuine HARDI hydraulic hose lines.
The hydraulic hoses should not be in use for longer than 5 calender years, including any storage time of maximum 2 years.
Even with proper storage and approved use, hoses and hose connections are subject to natural ageing, thus limiting storage
time and the time of use. However, it may be possible to specify the length of use from experience values, in particular when
taking the risk potential into account. In the case of hoses and hose connections made from thermoplastics, other guide
values may be decisive.
Never attempt to plug leaks in hydraulic hose lines using your hand or fingers. Escaping high pressure fluid (hydraulic oil) may
pass through the skin and ingress into the body. Risk of infection and serious injuries.
If you are injured by hydraulic oil, contact a doctor immediately.
When searching for leaks, use suitable aids to avoid the serious risk of infection and injury.
