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.
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.

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 machine and the tractor or on
the machine without having first applied the tractor
parking brake and placed the gearbox in the neutral
position.
Hydraulic circuit
Caution! The hydraulic circuit is under high pressure.
Maximum pressure at work: 200 bar.
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 damagedor worn. In caseof 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.

PTO shaft
Use only PTO shafts supplied with the machine or
recommended by the machine manufacturer.
The protective shield of the tractor PTO stub, the PTO
shaft guards and the protective shield 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. Check that the PTO shaft
guard can turn freely a full rotation independent of the
shaft.
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 to come to a complete stop.
If the primary PTO shaft is equipped with a torque limiter
or a free wheel, these must be fitted on the machine
side.
Ensure that the PTO shaft is always correctly fitted and
locked into place.
Before connecting the PTO shaft, ensure that the PTO
speed (rotational frequency) and direction of rotation are
in line with the machine manufacturer's
recommendations.
Before engaging the PTO drive, make sure that there are
no people or animals near the machine. Never engage
the PTO drive when the tractor engine is stopped.

Projection of stones and foreign objects
For driver safety, always use a tractor equipped with a
cab. Keep the ground to mow free of foreign bodies.
Avoid mowing on stony or rocky grounds. If this is not
possible, take extra safety precautions, such as
- Fit polycarbonate screens inside the tractor cab's side
and rear windows, or install narrow mesh guards on
their exterior.
- Increase the cutting height to avoid contact with
stones or rocks.
Never start a mower conditioner when other people are
close.
Even when the machine is used in accordance with its
purpose, objects may be projected. Stones and other
foreign objects projected by the moving parts can travel
a considerable distance. Keep all persons and animals
away from the danger zone.
The protection covers help reducing risks of projections.
Therefore, make sure that all mower protection devices
are in place and good condition prior to using the
machine.
Regularly check the condition of the protection covers.
Immediatly replace any worn, damaged or missing
cover.
