components:
•Operating Manual
•Warranty Card
1. Precautions
1.1 Before you Begin to Use Your Machine
•Read the instruction manual.
•Pay always special attention to the text and illustrations marked with this
symbol!
•These machines are intended for agricultural use only. Any use outside of this purpose shall
be considered as not intended use. Learn how to use your machine correctly and carefully!
•The machine may be dangerous when driven by not authorized individual or when operated
carelessly.
1.2 Health and safety regulations
•Before each start, check whether the tractor and machine are safe for road traffic and
operation!
•The tractor working with the machine must be equipped with the weights on the front axis!
Balance of the tractor with the attached machine, its steerability and braking ability must
always be kept.
•When connecting and disconnecting the machine to/from the tractor, its lifting and lowering
on the hydraulic lift of the tractor, setting the machine in the transport and working positions
and on the headlands, ensure that no bystanders and in particular children are present in the
vicinity of the machine. Perform these operations slowly, without sudden jerks!
•Never stay between the tractor and cultivator when the tractor’s engine is running!
•The machine may only be operated, maintained and repaired by the personnel who know its
construction and are aware of the existing hazards!
•There are some places where crushing or cutting may occur on the parts actuated by the
forces other than the human force (e.g. the hydraulic system). When connecting the
hydraulic hoses to the hydraulic system of the tractor, always ensure that the hydraulics is
depressurized! Check positions of the control levers of the tractor hydraulic system. Only
actuate the hydraulically operated attachments when there is nobody present within their
range of operation! Check the hydraulic hoses on regular basis and replace them with new
items when damaged or worn!
•When driving on highways with the machine attached, lock the operating lever against its
lowering!
•The attached warning and indicating signs contain information on safe work: they are
intended for your safety!
•Before you start work, learn thoroughly operation of all devices and actuators and functions

of the machine. It is too late for this after you start work!
•Avoid wearing any loose clothing, which could be caught by rotating components of the
machine.
•Always keep the machine clean in order to avoid fire!
•Always check the surroundings before you start operation. Make sure that you have sufficient
visibility!!
•Never back or reverse the tractor when the machine is lowered to the working position.
When reversing, pay attention to the components that protrude far away and do not use the
independent brakes of the tractor!
•Check air pressure in the wheels of the tractor and cultivator regularly.
•Never transport people on the machine and load it with any additional weights when
operating the machine or transporting it!
•Check and attach the traffic equipment, such as lighting, warning devices and possible
protective devices.
•Observe the admissible axial loads, total weights and transport dimensions.
•Check tightness of screws and nuts on regular basis and tighten them if required.
•Always use appropriate tools and wear safety gloves when changing tools.
•The spare parts must be conforming to the revisions specified by the manufacturer. This may
only be provided by the genuine spare parts. Use typical protection devices and pins for
securing all bolts of the unit (tractor + machine). Never use any temporary means of
protection, such as screws, bars, wires etc., which can cause damage to the machine or
tractor during transport and cause a safety hazard for other road users!
•Attach and disconnect the machine to/from the tractor after having parked the machine on
a flat and hardened surface and with the tractor engine stopped. Store the machines
