Dear customer!
We would like to thank you for the confidence in buying this implement.
The advantages of this implement will be shown, only, when operated and used
with due care and attention.
When handing over this implement your dealer has already instructed you with
regard to operation, adjustment and maintenance. But this short introduction re-
quires an additional detailed study of the instruction book.
Therefore read this instruction book carefully before the first use. Please pay at-
tention to the safety instructions mentioned in this instruction book.
Any changes and modifications carried out not being mentioned expressly in this
instruction book, may only be carried out with a written agreement of the manufac-
turer.
Ordering spare-parts
To each LEMKEN-implement an implement card is added, which shows all as-
semblies being relevant for that implement. The spare-parts list added to your im-
plement includes beside the relevant assemblies also those being not relevant for
your implement. Please ensure that only spare-parts will be ordered, which will
belong to assemblies being printed on the implement card respectively are shown
on the enclosed computer printout.
When ordering spare-parts please state type and serial No. of the implement. This
information will be found on the identification plate. Put down this data on the fol-
lowing table so that it is always available.
Type of implement:
Serial No.:
Only use genuine LEMKEN spare-parts. Spurious parts negatively influence the
function of the implement, show a shorter lifetime and increase in nearly all cases
the maintenance effort.
We trust that you will understand that LEMKEN is unable to guarantee poor op-
eration and damage caused by using spurious parts!

Before using the machine, always check both it and the tractor for roadworthi-
ness and operational safety!
As well as the notes in these instructions the operator is advised to comply with
the generally applicable safety at work regulations and those relating to use of
the public highway!
When driving on public roads with a raised machine the lifting control lever
should be locked against unintentional lowering!
The fitted warning and advisory plates give important information for safe op-
eration; adhering to these increases your own security!
When using public roads adhere to applicable traffic rules!
The operator should familiarise him-/herself with all controls and their functions
before starting work. During work could be too late!
The clothing of the operator should fit tight. Avoid wearing any loose clothing!

Special care should be taken when the implement is coupled to or uncoupled
from the tractor.
When coupling or uncoupling the implement bring the supporting stands into
the corresponding position (standing safety)!
Fit weights only to the fixing points provided for that purposes!
Adhere to the maximum permissible axle loads, total weights and transport
width!
Fit and check transport gear, road lights and warning guards!

Safety Instructions
8
The release ropes for quick coupler latches should hang freely and in the low-
ered position must not release the quick coupling by themselves.
Never leave the driver's seat whilst in motion!
Handling behaviour, steerability and braking are influenced by mounted imple-
ments, trailers and ballast weights. Check for sufficient steerability and braking!
When driving round bends note the width of the machine and/or changing cen-
tre of gravity of the implement.
Put implement into operation only when all guards are fixed in position!
Never stay or allow anyone to stay within the operating area!
Never stay in the turning and slew area of the implement!
Do not operate any hydraulic controls while anybody is in the operating area!
On all pivoting parts actuated by power assistance (e.g. hydraulics) exists dan-
ger of injury by bruising and crushing!
Before leaving the tractor lower the machine to the ground. Apply the parking
brake, stop the engine and remove the ignition key!
Do not allow anybody between the tractor and implement if the parking brakes
are not applied!
Swing attachment arm to transport position and secure!
Attached Implements
Before mounting or dismounting implements on/from the three-point linkage,
move the raise / lower control to the position at which accidental raising or low-
ering cannot take place!
In the case of three-point linkage mounting, ensure that the tractor balls and
the mounting pins of the implement are of the same category!
There is the risk of injury from pinch and shear points in the three-point linkage
area!
When operating the external lift controls for the three-point linkage, do not
stand between the tractor and implement!

Safety Instructions

Always ensure sufficient lateral limitation for the three-point linkage of the trac-
tor in the transport position of the implement!
When driving on roads with the implement raised, the raise/lower control must
be locked to prevent lowering!
Hydraulic Equipment
The hydraulic pipes are under pressure!
When connecting hydraulic rams, the pipes must be connected as directed!
Always release hydraulic pressure from both tractor and implement before
coupling!
When connecting hydraulic pipes to the tractor ensure that incorrect use is
avoided. If the connections are reversed, the opposite function is carried out
(e.g. raising/lowering) and there is a risk of accidents!
Regularly check the hydraulic pipes and replace them in the event of damage
or signs of ageing. The replacement pipes must comply with the technical
specification as laid down by Lemken!
When searching for leaks appropriate aids should be used because of the dan-
ger of injury!
Hydraulic oil escaping at high pressure can penetrate the skin and cause seri-
ous injury! When injured see a doctor immediately! Danger of infection!
Before working on any hydraulic equipment - lower all implements/attachments,
release hydraulic pressure where possible and switch off the tractor engine!

3 PREPARATION OF THE TRACTOR
3.1 Tyres
The pressure - especially in the rear tractor tyres - must be equal. In heavy condi-
tions it may be necessary to add wheel weights and/or water ballast. (See manu-
facturer’s instructions).
3.2 Lift Rods
Adjust lift rods to equal length. (See manufacturer’s instructions).
3.3 Top Link
Where there are alternative fitting positions at the tractor for the top link, fit the top
link tractor-sided as hight as possible.
3.4 Check Chains or Sway Blocks of the Three Point Linkage
Check chains or sway blocks MUST be adjusted so that the lower links are always
free to move sideways during ploughing.
Attention! Some tractors are equipped with automatic „check devices“ which re-
quire special adjustments. If a tractor suddenly shows side draft or if
the L/H and R/H front furrow width of the plough is different, an
unlocked „check device“ couldbe the reason for that. In such a case
the function of the automatic „check device“ must be checked. (See
manufacturer’s instructions)
3.5 Hydraulics
For work the tractor hydraulics must be set to ’Draft’ or ’Mixed’ Control. See manu-
facturer’s instructions.

Preparation of the Tractor
15
3.6 Required Hydraulic Equipment
Following spool valves and return pipe connections must be available:
Required Spool Valves
single acting double acting
Turnover ram - 1
Turnover ram */**
(with return pipe connection at the tractor) 1 -
Turnover ram with Vari-Stop ** - 1
Turnover ram with Vari-Stop plus - 2
Hydraulic swing-in assembly - -
Memory ram
(hydraulic front furrow width adjustment) - 1
Attachment arm connected to the turnover ram - -
Attachment arm connected to a spool valve 1 -
Hydraulic overload safety device - 1
Hydraulic depth and transport wheel
Hydraulic depth and transport wheel - 1
* Can not be used in connection with Vari-Stop and Vari-Stop plus.
** If an attachment arm is fitted the hydraulic ram of the attachment arm must be con-
nected to a single acting spool valve.

Preparation of the Tractor
16
3.7 Axle Loads
The attachment of implements to the front- and rear-three point
linkage must not lead to exceeding the allowed total weight, the
allowed axle load and the allowed tyre load of the tractor.
The tractor front axle must always be loaded with 20 % of the
tractor dead weight at minimum.
Calculation of the minimum front ballast and the increasing of the rear axle
load:
GV= Weigth of front ballast (front implement)
TV= Front axle load of the tractor without mounted implement
TL= Tractor dead weight
TH= Rear axle load of the tractor without mounted implement
GH= Weight of the implement
Calculation of the minimum front ballast GVmin:
Calculation of the increasing of the rear axle load:
Minimum axle load increasing
The calculation of the required minimum front ballast and the increasing of the
rear axle load requires that all above mentioned measurements and weights are
known. If they are unknown and cannot be found out, there will be only one way to
avoid overloads:
Please weigh your tractor with mounted and lifted implement to find out the
actual rear axle loading and front axle unloading and that in comparison
with the axle loads of the tractor without implement!

4 USE
4.1 General Instructions
Before the first use it is recommendable - with fully lowered implement - to carry
out the following adjustments at the farm. Afterwards only few adjustment correc-
tions have to be carried out in the field.
4.2 Top Link Connection
Connect top link to headstock (1) and en-
sure that the top link rises slightly towards
the plough. Generally in hilly conditions
use the slotted hole (2) with ploughs hav-
ing 5-furrows or more. During work the top
link must always be tension loaded, espe-
cially when the top link is connected to the
slotted hole (2). Then the top link pin (3)
must always be positioned in front of the
slotted hole (2).
4.3 Adjustment of the outer Turnbuckle of the Adjustment Centre Op-
tiquick
The outer turnbuckle (2) has been adjusted
to the extreme to allow compact transport
on lorries. Adjust this turnbuckle to a length
similar to that of the main link (3). Final ad-
justments can take place in the field.

4.4 Length of the Top Link
Lower plough and adjust length of top link, so that the first body is approx. 1 to 3
cm higher than the rear one.
When the top link is fitted “in”the slotted hole, it must be adjusted with lowered
plough until the top link pin is unloaded but is still positioned in front of the slotted
hole and the plough is also 1 to 3 cm higher in front than in the rear.
4.5 Depth Control Wheel resp. Depth and Transport Wheel
Adjust the depth control wheel / depth and transport wheel to obtain the intended
working depth.
Swing the wheel rearwards against its stop and measure the vertical distance be-
tween wheel and ground. Make adjustments as required.
4.6 Clearance for the Turnover Operation
Raise the plough fully and then turn the
plough carefully.
Check whether there is sufficient clearance
between plough/depth wheel and ground.
If not, lengthen the inner turnbuckle (1), set
drawbar deeper, fit top link to a higher hole
in the headstock or use an hydraulic frame
swing-in assy.
When a Memory ram is fitted, the plough
frame can 1st be swung-in and 2nd the front
furrow width can be adjusted from the trac-
tor seat.
