If in doubt about the safety-relevant status of the machine, e.g. in case of leaking
operating fluids, visible damage or unexpected changes in travel behaviour:
Ø Immediately shut down and secure the machine.
Ø If possible, locate and rectify the faults by following these operating instruc-
tions.
Ø Rectify possible causes for damage (e.g. remove coarse dirt and tighten loose
screws).
Ø Have damage that could affect safety and that cannot be rectified by you recti-
fied by a qualified expert workshop.
Faulty coupling of the machine to the pulling tool of the tractor causes dangers,
which could result in severe accidents.
Ø Strictly comply with all operating instructions:
• These operating instructions
• Operating instructions of the tractor
Ø Exercise special caution when reversing the tractor. Never stand between
tractor and machine.
Ø Only park the machine on a firm and level surface. Before unhitching the
towed machine, lower it to the ground.
Ø Secure the machine against rolling away.
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.
Ø Connect the hydraulic hoses to the tractor only when the hydraulics on tractor
and machine are depressurised.
Ø 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.
Ø The hydraulic system is under high pressure. Check all lines, hoses and screwed
connections regularly for leaks and any visible external damage!
Ø Use only appropriate means when searching for leaks. Repair any damage im-
mediately! Oil sprays can cause burns and fire!
Ø Power sockets and connectors on the hydraulic connections should be marked
in order to exclude operating errors.
Ø In the event of injury, consult a doctor immediately.
Ø Secure and lock the control unit on the tractor if not in use!
Ø Replace hydraulic hoses at the latest after six years, see Maintenance overview.
Ø To prevent unintentional machine movements due to air trapped in the hy-
draulic cylinders these cylinders must already be filled with hydraulic oil before
installing them in the machine. The cylinder and hose assembly are then bled
by retracting and extending the cylinder several times.
