Hydraulics
The hydraulic system is under high pressure.
The machine's hydraulics has several functions,
which can cause injury to persons or damage to
the machine if operated incorrectly:
Escaping fluid may penetrate the skin.
•
Hydraulically supported machine parts may
•
drop.
Hydraulic components may be flung away.
•
Pressurised hydraulic hoses may whip about
when detaching them.
Do not connect hydraulic hoses to the tractor
¾
before both the hydraulics on machine and
tractor are de-pressurised.
Lower all hydraulically lifted parts (e.g. wings,
¾
packer, undercarriage, etc.) to the ground
before performing any work on the hydraulic
system. Depressurise the hydraulics on the
tractor and implement side.
The hydraulic system is under high pressure.
¾
Check all lines, hoses and screwed con-
nections regularly for leaks and any visible
external damage!
Use only appropriate means when searching
¾
for leaks. Repair any damage immediately!
Oil sprays can cause injuries and fire!
Power sockets and connectors on the hydrau-
¾
lic connections should be marked in order to
exclude operating errors.
In the case of injury, contact a doctor imme-
¾
diately!
Secure and lock the control unit on the tractor
¾
if not in use!
Replace hydraulic hoses at the latest after six
¾
years, see Maintenance overview.
Pressure accumulator
The hydraulic system is equipped with pressure
accumulators.
Observe the regulations applying at the location
of use during operation. The owner is solely
responsible for complying with them.
10
Do not open or work (welding, soldering, drill-
¾
ing) on pressure accumulators. Even when
empty, the tanks are still preloaded by gas
pressure.
Maintenance and repair work on the pres-
¾
sure accumulator must only be carried out by
trained and qualified personnel.
Brake system
Depending on the equipment, the machines can
be equipped with a pneumatically or hydrauli-
cally operated service brake system.
For road travel the brake system must always
be connected and fully functional.
After coupling the machine and before trans-
¾
portation you should always check the func-
tion and condition of the brake system.
Check the setting on the brake pressure
¾
regulator.
Always release the parking brake before start-
¾
ing to drive.
Always secure the machine against rolling
¾
away and apply the parking brake before
unhitching.
Adjustments and repair work on the brake sys-
tem must only be carried out in a professional
workshop or by an operator, who has been
specially trained by HORSCH for this purpose.
Overhead lines
When unfolding or folding the wings, the ma-
chine may reach the height of overhead lines.
Possible voltage flashover to the machine may
cause fatal electric shock or fire.
Keep a safe distance to electric high voltage
¾
power lines with the wings folded and when
unfolding or folding the wings.
Do not unfold or fold the wings in the vicinity
¾
of pylons and power lines.
Never leave or access the machine under
¾
overhead lines to avoid possible risks of
electric shock or voltage flashover.
