1. Dear Owner
In buying a Kuhn machine you have chosen wisely. Into it have gone years of thought, research and
improvement. You will find, as have thousands of owners all over the world, that you have the best that
engineering skill and actual field testing can produce. You have purchased a dependable machine, but only
through proper care and operation can you expect to receive the performance and long service built into it.
This manual contains all the necessary information for you to receive full efficiency from your machine. The
performance you get from this machine is largely dependent on how well you read and understand this
manual and apply this knowledge. Please DO NOT ASSUME YOU KNOW HOW TO OPERATE AND
MAINTAIN YOUR MACHINE before reading this manual carefully. KEEP THIS MANUAL AVAILABLE FOR
REFERENCE. Pass it on to the next owner if you re-sell the machine.
Your KUHN dealer can offer a complete line of genuine KUHN service parts. These parts are manufactured
andcarefullyinspectedinthesamefactorythatbuilds the machineto assure high quality and accurate fitting
of any necessary replacements.
About improvements
We are continually striving to improve our products. We therefore reserve the right to make improvements
or changes when it becomes practical to do so, without incurring any obligations to make changes or
additions to the equipment sold previously.
Wear parts
Wearing parts fitted on our machines have been tested in very different situations to optimize their service
life. Nevertheless, the service life depends highly on the conditions of use (products to handle, soil, weather
conditions, etc...).
Document illustrations
The illustrations in this manual may be based on one type of machine only. However, all instructions apply
to all machines covered in this manual.

4.2 Safety instructions
4.2.1 Introduction
The machine must only be operated, maintained
and repaired by competent persons who are familiar
with machines' specifications and operation and
aware of safety regulations for preventing
accidents.
The operator must imperatively respect safety
instructions in this manual and in the warnings
posted on the machine. The operator is also obliged
to respect current legislation concerning accident
prevention, work safety and public traffic circulation.
Designated use of the machine also means
following operation, maintenance and repair
recommendations given by the manufacturer, and
using only genuine spare parts, equipment and
accessories, as recommended by the manufacturer.
The manufacturer is not held liable for any damage
resulting from machine applications other than
those specified by the manufacturer. Any use other
than the designated operation is at the risk and
responsibility of the operator.
The manufacturer is not held liable for any damage
or accident resulting from machine modifications
carried out by the operator himself or by a third party
without previous written agreement from the
manufacturer.
4.2.2 Read and follow the safety instructions
- Before using the machine, carefully read all the
safety instructions in this manual and the warnings
placed on the machine.
- Before starting work, the operator must be familiar
with all machine controls, handling devices and
their functions. It is too late to learn once work has
been started!
- Never let anyone operate the machine who is not
trained to do so.
- Should you have any difficulties in understanding
any parts of this manual, please contact your
KUHN dealer.

4.2.3 Precautions to be taken before carrying
out any operations on the machine
- Before leaving the tractor or before adjusting,
maintaining or repairing the machine, disengage
the PTO drive, turn off the engine, remove ignition
key and wait until all moving parts have come to a
complete stop and apply park brake.
4.2.4 Precautions to take before using the
machine
- Do not wear loose clothing which could become
caught up in moving parts.
- Wear the appropriate protective clothing for the
work in hand (gloves, shoes, goggles, helmet, ear
defenders, etc.).
- Ensure that all operating controls (ropes, cables,
rods, etc) are placed so as they cannot be
operated unintentionally and cause damage or
injury.
- Before operating the machine, check tightness of
nuts and bolts, particularly on fixing elements
(tines, forks, blades, knives, etc). Retighten if
necessary.
- Before operating the machine, ensure that all the
safety guards are firmly in place and in good
condition. Immediately replace any worn or
damaged guard.

4.2.5 Precautions when driving
- Tractor handling, stability, performance and
braking efficiency are all affected by weight
distribution, trailed or mounted implements,
additional ballast and driving conditions. It is
therefore of great importance that the operator
exercises caution in every given situation.
- Groundspeed must be adapted to ground
conditions as well as to roads and paths. Always
avoid abrupt changes of direction.
- Be particularly cautious when turning corners,
paying attention to machine overhang, length,
height and weight.
- Never use a narrow track tractor on very uneven or
steeply sloping ground.
- Never leave the tractor seat while the machine is
operating.
- Carrying people or animals on the machine when
working or in transport is strictly forbidden.
4.2.6 Precautions when driving on public
roads
Dimensions
Depending on the dimensions of the machine,
contact the relevant authorities to ensure that it can
be legally transported on public roads.
- If the machine is over the maximum legal size,
follow the local regulations for special
transportation of oversize equipment.
Gross weight and weight per axle
- Respect the tractor gross weight, its lift capacity or
the permissible maximum load on the attachment
and the maximum load per axle.
- The front axle load (1) must never, under any
circumstances, be less than 20% of the tractor's
unladen weight. If necessary, add ballast weights
to the front or to the rear to preserve the steering
and braking efficiency.
- Do not exceed the gross machine weight rating or
the maximum machine axle load allowed.

For machines with hoppers or tanks:
• If the total weight exceeds the machine's
total gross weight, empty the hopper to
travel on public roads.
• In any case, we recommend to travel on
public roads with empty hoppers and
tanks.
Transport position
- Before transporting the machine on public roads,
place the machine into its transport position,
according to the instructions in this manual.
Lights and indicators
- Before transporting the machine on public roads,
ensure that all legally required lightings and
signallings are in place.
- Ensure that lightings and signallings are clean and
in good working order. Replace any missing or
broken equipment.
- Always obey current regulations for driving
on roads.
4.2.7 Maximum speed
- Always keep to the legal speed limit for driving a
tractor-machine assembly on public roads.

4.2.8 Precautions when coupling
- Before attaching the machine, make sure that it
cannot accidentally start moving (chock the
wheels) and that the parking stand is in the right
position.
- The machine must only be attached to the hitch
points provided for this purpose.
- Do not stand between the machine lower hitching
points or between the tractor lower hitching points
during coupling maneuvers.
- Never stand between the tractor and the machine
when operating the three point linkage.
- Do not stand between the machine and the tractor
or on the machine without having first applied the
tractor parking brake and placedthe gearbox in the
neutral position.

4.2.9 Hydraulic circuit
Caution! The hydraulic circuit is under high
pressure. Maximum pressure at work: 200 bar
(2901 psi).
- Before connecting hoses to the tractor hydraulics,
ensure that tractor and machine circuits are not
under pressure. Before disconnecting a hose,
depressurize the hydraulic circuit.
- To avoid making incorrect connections, mark
hydraulic couplers and corresponding hoses with
colors. WARNING! Functions could be reversed
(for example: lift/lower) and cause accidents.
- Regularly make visual inspection to check if
hydraulic hoses are damaged or worn. In case of
normal wear, the hydraulic hoses must be
replaced every 5 years. Damaged or worn hoses
must immediately be replaced. When replacing the
hydraulic hoses, only use hoses with the
specification recommended by the manufacturer of
the machine.
- To locate a leak, use appropriate means. Protect
body and hands from liquid under pressure.
- Any liquid under pressure (particularly oil from
hydraulics) can penetrate the skin and cause
severe injury. If injured, see a doctor immediately,
there could be danger of infection.
- Before any adjustments, maintenance or repairs
are carried out, lower the machine to the ground,
depressurize the hydraulics, turn off the engine,
remove ignition key and wait until all moving parts
have come to a complete stop.
