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. Failure to follow the instructions contained
in this manual could result in product or property
damage, severe personal injury, or death. All applicable
safety procedures, codes and requirements of any
federal, provincial, state and local agencies, as well as
safe working practices and good judgment, must be
used by personnel when assembling, servicing,
adjusting or operating this equipment.
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.
Safety shutdown procedure
Before leaving the tractor or before adjusting,
maintaining or repairing the machine, depressurize
hydraulics, turn off the engine, remove ignition key,
apply parking brake and wait until all moving parts have
come to a complete stop.
Introduction
The machine must only be operated, maintained and repaired by qualified persons who are familiar with the
machines' operation and understand safety regulations and procedures for preventing accidents.
The operator must follow the 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.
The intended use of the machine includes following all operation, maintenance and repair recommendations
given by the manufacturer, and using only genuine spare parts, equipment and accessories, as recommended

Safety
Precautions to take before using the
machine
Do not wear loose clothing which could become caught
up in moving parts.
Wear appropriate protective clothing (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 components that the machine
uses to process material (tines, forks, blades, knives,
etc). Retighten if necessary.
Precautions when driving
Tractor handling, stability, performance and braking
efficiency are all affected by weight distribution, trailedor
mounted implements, additional ballast and driving
conditions. It is therefore of great importance that the
operator exercises caution in every given situation.
Drive speed 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.
Avoid driving on loose fill, rocks, inclines, ditches, and
holes.
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.
Lights and indicators
Before transporting the machine on public roads, ensure
that all legally required lights and indicators are in place.
Ensure that lights and indicators 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) and that 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
Caution! The hydraulic circuit is under high pressure.
MAXIMUM operating pressure = 3000 psi (200 bar)
Before connecting hoses to the tractor hydraulics,
ensure that tractor and machine circuits are not under
pressure. Before disconnectinga 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. 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 leaving the tractor or before adjusting,
maintaining or repairing the machine, always perform
the safety shutdown procedure.

Precautions when moving rake arms
When moving the machine from the transport position to
the working position and vice versa, make sure that
nobody is within the machine pivoting area.
Remote controlled components
Danger of crushing and shearing can exist when
components are operated by hydraulic or pneumatic
controls. Keep away from these danger zones.
Tires
Regularly check the tire pressure. Follow manufacturers'
recommendations on tire pressure. Assembly,
disassembly and repair of wheels and tires must only be
carried out by competent persons who are equipped with
standardized tools. Before any work is performed on the
wheels, ensure that the machine is perfectly stable so
that it cannot move accidentally. Place chocks on both
sides of each transport wheel.
Safety decals
Safety warnings are placed in safety decal form on
various parts of the machine. They are there to warn you
of potential dangers and to tell you how to avoid
accidents.
Always keep the safety decals clean and readable, and
replace them when they are worn, damaged, missing or
illegible.
Waste disposal
Respect the environment! Never spill pollutants (oil,
grease, filters, etc.) on the ground, never pour them
down the drain and never discard them in any other
place where they could pollute the environment. Never
throw away or burn a tire. Always take waste to
specialized recycling or waste disposal centers.

Precautions for maintenance and repair
work
Before leaving the tractor or before adjusting,
maintaining or repairing the machine, always perform
the safety shutdown procedure.
Rest the machine on the ground, release the pressure
from the hydraulic circuit and leave the machine to cool
down.
Make sure that the parts of the machine that need to be
lifted for maintenance or repair work are firmly propped
up.
Repairs on elements under pressure or tension (springs,
pressure accumulators, etc.) must only be carried out by
competent persons with regulation equipment.
Wear appropriate protective clothing (gloves, shoes,
goggles, helmet, ear defenders, etc.).
Do not solder, weld or use a blow torch near fluids under
pressure or flammable components. If welding is
required on this unit, donot allow the electrical current to
flow through the bearings. Ground the welder directly to
the part being welded.
For your own safety and for correct machine operation,
only use original manufacturer parts.
Projection of stones and foreign objects
For driver safety, always use a tractor equipped with a
cab.
Even when the machine is usedproperly, objects may be
thrown. Stones and other foreign objects thrown by the
moving parts can travel a considerable distance. Keep
all persons and animals away from the danger zone.
