Dear customer!
We would like to thank you for your 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 will have already instructed you
with regard to operation, adjustment and maintenance. But this short introduction
requires an additional detailed study of the instruction book.
Therefore read this instruction book carefully before the first use. Please pay
attention 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
manufacturer.
Ordering spare-parts
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
following 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
operation and damage caused by using spurious parts!

1 EFFECTS OF CERTAIN PESTICIDES ON THE FIELD SPRAYER
At the time of manufacture of the machine, the manufacturer is aware of some of
the authorised pesticides and mixtures which can have damaging effects on the
field sprayer materials. These are usually solvent-based pesticides and mixtures
such as BETANAL with TRAMAT, (BETANAL-TANDEM), ELANCOLAN, ILOXAN,
LASSO, MUDECAN, RACER, RIPCORD 40, TERIDOX, STOMP, liquid manure
(AHL) but also
Mixtures with AHL: ALANDAN, or liquid NEXID 100.
Damaging effects can also occur with the subsequent products of the above
materials and mixtures.
IMPORTANT! For mixtures not “covered” by any equipment application, it
is recommended to test the materials mentioned above with
several hours of submersion tests before starting work.
Pesticides or other substances which tend to harden or stick
must not be used with the machine.
ATTENTION! The usage instructions of the respective pesticide
manufacturer must be strictly followed before starting work.
The equipment parts which can be affected by the pesticides mentioned above
are usually hoses, spray lines, seals, tanks and pump diaphragms.
If hoses become particularly soft or seals or diaphragms swell, these are signs of
damaging effects. The affected parts must then be replaced immediately. These
damaging effects can often be avoided if the machine is intensively flushed
immediately after dispensing the materials and mixtures shown above (e.g. rinsing
and disposal of the technical residues on the field).

2 SAFETY INSTRUCTIONS
General Safety Instructions
•Before using the machine, always check both it and the tractor for
roadworthiness 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
operation; adhering to these increases your own safety!
•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!
•To avoid danger of fire keep the implement clean!
•Before beginning to drive check surroundings area (children)!
•Sitting or standing on the implement during operation or during transport is not
permissible.
•Attach implements as advised and only to the stipulated positions!
•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 those purposes!
•Adhere to the maximum permissible axle loads, total weights and transport
width!
•Fit and check transport gear, road lights and warning guards!
•The release ropes for quick coupler latches should hang freely and in the

8
lowered 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
implements, trailers and ballast weights. Check for sufficient steerability and
braking!
•When driving round bends note the width of the machine and/or changing
centre 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
danger 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!
Trailed implements
•Secure machine and tractor against unintended rolling away!
•Never exceed the maximum permissible load of the drawbar or hitch!
•When fitting the implement to a drawbar or hitch, ensure sufficient movement
at the hitch-point!

9
Brakes
•Check the function of the brakes before starting work!
•The brake systems must be checked thoroughly at regular intervals!
•Adjustment and repairs to the brake system must only be carried out by
approved workshops or approved brake service shops. Only use the specified
brake fluid and renew as specified.
Hydraulic equipment
•The hydraulic equipment is under high pressure!
•When connecting hydraulic rams and motors, the hydraulic hoses must be
connected as directed!
•Always release hydraulic pressure from both tractor and machine before
connecting the hydraulic hoses.
•Coupling sleeves and connectors for hydraulic functional connections between
the tractor and machine should be marked in order to rule out operator errors. If
the connections are reversed, the opposite function is carried out (e.g.
raising/lowering) and there is a risk of accidents!
•Check the hydraulic hoses regularly and replace them in the event of damage
or signs of ageing! The replacement hoses must comply with the technical
specification as laid down by Lemken!
•When searching for leaks, appropriate equipment should be used because of
the danger of injury!
•Hydraulic oil escaping at high pressure can penetrate the skin and cause
serious injury! Consult a doctor immediately in the case of injury. Danger of
infection!
•Before working on any hydraulic equipment, lower all implements/attachments,
release hydraulic pressure where possible and switch off the tractor engine!

10
Tyres
•When working on the tyres, make sure that the machine has been placed on
the ground safely and that it is secured by chocks against unintentional rolling
away!
•Fitting tyres requires knowledge and special tools!
•Repair work on the tyres and wheels must only be carried out by trained
personnel and with suitable tools!
•Check the air pressure regularly. Adhere to the advised air pressure!
Maintenance
•Repair-, maintenance- and cleaning operations as well as adjustments and
remedy of function faults should principally be conducted with engine stopped and
brakes applied. Remove ignition key!
•Check and tighten nuts and bolts regularly!
•When conducting maintenance work on a lifted implement always place
suitable supports underneath!
•For replacing any tools with cutting edges always use suitable tools and
gloves!
•Dispose of old oils, grease and filters as prescribed by law.
•Before working on the electric gear disconnect battery cables!
•When conducting electrical welding operations on the tractor or on the
mounted implement remove cable from the generator and the battery!
•Any spare parts fitted must meet with the implement manufacturer's fixed
technical standards! This is for example ensured by using genuine spare parts!
•To avoid danger of explosion only use nitrogen for filling up gas tanks!
