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 theconditions of use (products to handle, soil, weather
conditions, etc...).
Designated use of the machine
The FC813R mower conditioner must only be used for the work for which it has been designed: mowing on
the ground of hay fields, grass silage fields and improved pastures for the purpose of harvesting fodder for
feeding livestock.
From a safety point of view, the machine is not designed to mow road sides.

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.

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 check the hydraulic hoses. Anyway, 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,

4.2.10 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.
