PREFACE:
When buying the machine, check completeness of its accessories that include the following
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 unfolded.
•Store the machine in the locations inaccessible for unauthorized people or animals when not
in use.
•Besides the above guidelines, follow the general safety rules.
1.3 Servicing
•Service the machine when it is lowered onto the ground! If the machine is
coupled with the tractor, engine of the tractor must be off and brakes on!
• Use only tools in good technical condition and genuine materials and spare
parts for servicing
•Always protect the machine with appropriate supports when performing any maintenance or
repair work on the machine lifted up.

1.4 Transport on highways
•Never exceed the speed limits allowed on highways and follow traffic
regulations of the respective country!
•Pay special attention when passing and overtaking other vehicles and on
curves (the unit is pivotally connected to the tractor)!
•The machine, as the part of the vehicle that protrudes outside the rear side outline of the
tractor covering the rear lamps of the tractor, poses a threat for other vehicles in the traffic.
•When transporting the machine on highways, always use warning lights, distinguishing plate
and side reflectors.
•Maximum width of the machine, which can be moved on highways is specified in the detailed
regulations of the country of use. They should be observed

3. Operating Manual
3.1 First Start
Before the first start of the machine:
•read the Operating Manual thoroughly
•check technical condition of the unit, and in particular, condition of its working parts,
mechanisms protecting tines from overload and the hydraulic system. When finding any
damaged or worn parts, replace them with new ones
•check tightening of all screws, bolts and nuts. Tighten any loose nuts especially at the
beginning of operation of the machine
•check fitting of the quick-connectors of the hydraulic hoses of the machine to the sockets
on the tractor
•check, whether the disc coulters, rollers and spindles (turnbuckles) can rotate without any
jams
•check the pressure in tyres acc. to the manufacturer’s recommendations
•check, whether the components requiring lubrication are lubricated
•check, whether the machine attachment system fits the tractor attachment system
3.2 Preparation of the Unit (Tractor + Machine)
•pressure in the tractor wheels must be equal on the same axle in
order to provide uniform working depth of the machine
•the tractor lower links (c) must be stiffened (lock the oblong holes)
and at the same height above the ground level
•set the lifting rods of the tractor links (w) so that you can pull down
the lower links to the height below the hitch axle in order to achieve
the required working depth, while obtaining sufficient lifting height
of the links for transport
•mount the front axle weights in order to keep balance of the tractor
and the machine
•quick-connectors of the machine hydraulic hoses must fit the
sockets on the tractor
•the hitch axle should be in the middle of the machine
•category of the lower articulated joint of the hitch axle must be the
same on both the tractor and the machine sides!

3.5 Adjustment of the Cultivator
3.5.1. Working Depth Adjustment - KOS PREMIUM
KOS PREMIUM units are designed for operation up to 15 cm with undercutters and up to 30 cm
without undercutters. Do not exceed these values.
•perform hydraulic adjustment by pressurizing the cylinder [A] from the tractor cab, which
extends the cylinder. Then, put on the required number of stops [B] and pressurize the
cylinder [A] again to slide it back to the stops [B]. Through this, you can raise or lower the
rear roller of the machine. Secure the cylinder [A] against dropping down with the lever
[C].
•when adjusting the working depth with the cylinder, keep in mind the parallel position of
the machine frame during operation. Lower the machine correctly on the tractor three-
point linkage/hitch.
•if required, repeat the steps above several times to obtain the desired working depth.
•after setting the working depth, you can begin adjustment of the disc harrow.
If the adjustment range does not match the actual field conditions, you can change it by varying
the cylinder length:
•remove the nut and pull out the bolt [D]. Caution: the cylinder tip can be
released freely, endangering your health, so support or suspend it
•extend the cylinder to its extreme position [A] by applying pressure to it
•screw the cylinder head in or out, aligning the hole in it with the hole in the
carriage
•secure the cylinder with the bolt and the nut
