2. Safety instructions
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!

to do so.
Should you have any difficulties in understanding certain
parts in this manual, please contact your KUHN dealer.
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.
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

Safety
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-protectors,
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.
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 ofthe 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.

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
Check that the tractor's authorized gross weight as well
as its lift capacity and maximum weight per axle are not
exceeded.
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.
Transport position
Before transporting the machine on public roads, place
the machine into its transport position, according to the
instructions in this manual.
Lightings and signallings
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.
Maximum speed
Always keep to the legal speed limit for driving a tractor-
machine assembly on public roads.
Always obey current regulations for driving
on roads.

Safety
Precautions when coupling
Before attaching the machine, make sure that it cannot
accidentally start moving (chock the wheels) andthat the
parking stand is in the right position.
The machine must only be attached to the hitch points
provided for this purpose.
Never stand between the tractor and the machine when
operating the three point linkage.
Do not stand between the tractor and the machine
without ensuring that the parking brake is applied.
Hydraulic circuit
Beware : The hydraulic circuit is under pressure.
Maximum pressure at work: 200 bar (2857 psi).
Before connecting hoses to the tractor hydraulics,
ensure that tractor and machine circuits are not under
pressure.Beforedisconnectinga 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 check the hydraulic hoses. In case of normal
wear, replace the hydraulic hoses every 5 years.
Damaged or worn hoses must immediately be replaced.
When replacing the hydraulic hoses, make sure to use
hoses with the specifications and quality 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 on the ground,
depressurize the hydraulics, turn off the engine, remove
ignition key and wait until all moving parts have come to
a complete stop.

PTO shaft
Use only PTO shafts supplied with the machine or
recommended by the manufacturer.
The protective shield of the tractor PTO stub, the PTO
shaft guards and the protective covering of the machine
input shaft must always be in place and in good
condition.
Make sure that the PTO shaft guards are secured with
the safety chains provided.
Any worn or damaged guards must be replaced
immediately. A worn guard or an unprotected PTO shaft
can cause a serious or even a lethal accident.
Do not wear loose clothing that could be caught in the
rotating PTO shaft.
Before attaching or removing a PTO shaft, or before
doing any work on the machine, disengage the PTO
drive, turn off the engine, remove ignition key and wait
for all moving parts have come to a complete stop.
