1 About these instructions
1.1 Introduction
These operating instructions are important and belong to the
machine's scope of delivery.
These operating instructions must be available to the user at the place
of use.
nAlways read chapter "Safety" before using the machine for the rst
time.
nRead chapter "Operation - Basic operation" before using the
machine for the rst time.
nBefore starting work, also read the relevant steps in the operating
instructions.
INFORMATION
In other documents and in sections of these operating
instructions, the machine is also referred to as an imple‐
ment.
About these instructions
en-GB | Item no. 17516276 | BA 01/2023-09 1

These operating instructions describe operation of the machine after
initial commissioning by the LEMKEN sales partner and handover to the
operator.
Prior to operation, initial commissioning and instruction in operation,
setting/adjustment and maintenance must have been carried out.
These instructions describe the machine in combination with a tractor.
If the requirements placed on the tractor are also met by other
machines or vehicles, the respective description can also be applied
in these cases.
Operation of the tractor, including its relevant functions, is not part of
these operating instructions. The operator and the user are responsible
for observing the operating instructions of the tractor.
For an unambiguous assignment of this document to the machine,
transfer the following data from the type plate of the machine:

2 Safety
2.1 Machine limits
The machine is used for soil cultivation on agricultural land.
It may only be used in accordance with the recognised rules of good
agricultural practice.
The permitted working depth is limited to the cultivatable soil horizons.
Use on heavily or deeply frozen soils, in soil horizons with unweathered
parent rock and soil horizons with loose rock or solid bedrock is not
regarded to be in compliance with the designated purpose.
Further information on the performance limits of the machine can be
found in Ä Chapter 12 ‘Technical data’ on page 79 of these operating
instructions.
The machine is carried or trailed by a suitable tractor. If necessary, other
functions of the machine are driven by the tractor.
How to check the suitability of a tractor is described in
Ä Chapter
4.1.2 ‘Ensuring suitability of the tractor’ on page 26 of these operating
instructions.
The machine with the dened hazardous area is operated and moni‐
tored by the user on the tractor. When using an autonomous tractor,
monitoring by the autonomous tractor or additional systems must be
ensured.
The power supply to the machine is provided by the tractor and
includes hydraulic, electric and mechanical power.
The actual service life of a machine is not limited to a specic time
period as long as the machine is in ecient working order. The ecient
working order depends to a large extent on the operating conditions,
proper maintenance and the use of suitable operating materials, spare
parts and wearing parts in accordance with the operating instructions.
The dimensions of the machine must always be considered in combina‐
tion with the tractor.
The dimensions of the machine vary in the operating position and the
transport position and can be changed by swivelling components.
Information on the dimensions of the machine can be found in
Ä Chapter 12 ‘Technical data’ on page 79 of these operating instruc‐
tions.

The machine and the area in the immediate vicinity of the machine
is deemed a hazardous area. This includes the space over the entire
width, length and height of the machine, as well as an additional safety
distance of two metres to the machine.
The hazardous area varies in the operating position and the transport
position and can be changed by swivelling components.
The hazardous area moves with the machine when it is moved.
2.2 Requirements of operators, users and service personnel
Operators within the meaning of these instructions are obliged to
inform all the users about correct application of the machine and the
respective hazards.
This can be done on the basis of these operating instructions. Opera‐
tors are responsible for ensuring that the operating instructions are
always available at the machine and that the users observe the oper‐
ating instructions.
Operators must also provide users with any necessary personal protec‐
tive gear.
Within the meaning of these instructions, users are persons who drive,
adjust, operate or maintain the machine. Users must be able to use the
machine safely.
This means:
nUsers understand how the machine works.
nUsers know and are able to avoid dangers.
nUsers are physically capable of controlling the machine.
In order to use the machine as intended and in a professional manner,
users must have the required technical (agricultural) knowledge.
Unless otherwise indicated, users may perform all of the activities
described in these operating instructions themselves.
Certain activities should only be performed by service personnel, e.g.
work on braking systems. These activities are indicated in the operating
instructions by the symbol .
Service personnel within the meaning of these instructions are all per‐
sons who maintain and repair safety-relevant components.
Service personnel are qualied for these activities based on their
training and expertise (for example agricultural machine mechanics).
