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.
¾
Do not connect hydraulic hoses to the tractor
before both the hydraulics on machine and
tractor are de-pressurised.
¾
Lower all hydraulically lifted parts (e.g. wings,
packer, undercarriage, etc.) to the ground
before performing any work on the hydraulic
system. Depressurise the hydraulics on the
tractor and implement side.
¾
The hydraulic system is under high pressure.
Check all lines, hoses and screwed con-
nections regularly for leaks and any visible
external damage!
¾
Use only appropriate means when searching
for leaks. Repair any damage immediately!
Oil sprays can cause injuries and fire!
¾
Power sockets and connectors on the hydrau-
lic connections should be marked in order to
exclude operating errors.
¾
In the case of injury, contact a doctor imme-
diately!
¾
Secure and lock the control unit on the tractor
if not in use!
¾
Replace hydraulic hoses at the latest after six
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.
¾
Do not open or work (welding, soldering, drill-
ing) on pressure accumulators. Even when
empty, the tanks are still preloaded by gas
pressure.
¾
Maintenance and repair work on the pres-
sure accumulator must only be carried out by
trained and qualified personnel.
Maintenance and repair work on the pressure
accumulator must only be carried out by trained
and qualified personnel.
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.
¾
Keep a safe distance to electric high voltage
power lines with the wings folded and when
unfolding or folding the wings.
¾
Do not unfold or fold the wings in the vicinity
of pylons and power lines.
¾
Never leave or access the machine under
overhead lines to avoid possible risks of
electric shock or voltage flashover.
What to do in case of voltage flashover
Voltage flashover generates high electric volt -
ages on the outside of the machine. This results
in extreme voltage differences at the ground
around the machine. Wide strides, laying on the
ground or supporting yourself with your hands
on the ground can cause life-threatening electric
currents (pace voltage).
¾
Do not leave the cabin.
¾
Do not touch any metal objects.
¾
Do not create a conductive connection to
ground.
¾
Warn persons: DO NOT come near the
machine. Electric voltages at the ground can
cause severe electric shock.
