•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 operated by not authorized individual or when
operated carelessly.
1.2 Health and safety regulation
•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
or on front jack. 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 the machine 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
