must also be respected.
2. Advice is indicated on the machine, specifying safety recommendations in order to prevent accidents.
3. When travelling on public roads, the operator must respect all road traffic regulations.
4. Before starting work, the operator must be familiar with all machine controls, handling devices and their
functions. Once at work, it is too late to do so!
5. Useatractorequippedwithasafetycab.Keepwindowsandroofhatchclosedforreducedsoundlevelwhile
operating the PTO drive implement.
6. Beforestartingupthemachineandbeginningwork,checkthesurroundingarea(bewareofchildren!).Make
sure there is sufficient visibility.
Keep all people and animals away from the danger zone of the machine (risk of projection!).
7. Carrying people or animals on the machine when working or in transport is strictly forbidden.

12. Do not surpass the maximum axle load or the overall transport weight as prescribed by the manufacturer.
13. Do not exceed the maximum transport width authorized by road traffic regulations.
14. Before transporting the machine on public roads, ensure that all legally required guards and indicators
(lights, reflectors ...) are in place and in good operation.
15. All operating controls (cords, cables, rods...) must be positioned so that they cannot be set off accidently,
risking accident or damage.
16. Before traveling on public roads, put the machine into its transport position as instructed in this operator’s
manual.

17. Never leave the tractor seat while the machine is operating.
18. Drive speed must be adapted to ground conditions as well as to roads and paths.
Always avoid abrupt changes of direction.
19. Precision steering, tractor adherence, road holding and efficient braking are influenced by the type of
implement, weight, ballast of front axle, ground or road conditions. It is therefore of utmost importance to
be cautious in every given situation.
20. Be particularly cautious when turning corners, paying attention to machine overhang, length, height and
weight.
21. Keep clear of the machine operating area.
22. WARNING ! Danger of crushing and shearing can exist when components are operated by hydraulic or
pneumatic controls.
23. Before leaving the tractor or before adjusting, maintaining or repairing the machine, turn off the engine,
remove the ignition key and wait until all moving parts have come to a complete stop.
24. Do not stand between the tractor and the machine unless the hand brake is tight and/or stops have been
placed under the wheels.
25. Beforeanyadjustments, maintenance or repairsarecarried out, ensure thatthemachinecannot be started
up accidentally.
PRECAUTIONS TO BE TAKEN BEFORE OPERATING THE MACHINE
1. Do not wear loose clothing which could be caught up in moving parts.
2. Wear the individual protection equipment corresponding to the work which is planned (gloves, shoes, eye
protection, helmet, ear protectors...).
3. All operating controls (cords, cables, rods ...) must be positioned so that they cannot be set off accidentally,
causing accident or damage.
4. Beforeoperatingthemachine,check thetightnessofallnutsandbolts, particularly onrotatingparts(blades,
tines, knives, spades ...)
5. Beforeoperatingthemachine, ensurethatallsafety guards are firmly in place andingoodcondition.Ifworn
or damaged, replace immediately.
ATTACHMENT
1. When attaching or removing the machine from the tractor, position hydraulic lift control lever in such a way
that it cannot be set off accidentally.
2. When attaching the machine to the tractor 3-point linkage, ensure that diameter of the link pins corresponds
to the diameter of the ball joints.
3. WARNING ! Danger of crushing and shearing can exist in the lifting zone of the 3-point linkage !
4. Donotstandbetweenthetractorandthemachinewhenoperatingtheoutercontrolleveroftheliftmechanism.
5. In transport, the machine lift mechanism should be stabilized by tractor tie rods to avoid floatation and side
shifting.
6. When transporting the machine in the raised position, lock the lift control lever in place.

HYDRAULIC SYSTEM
1. Beware ! The hydraulic circuit is under pressure (maximum working pressure : 200 bars/2900 psi).
2. When fitting hydraulic motors or cylinders, ensure that connections have been made correctly, as per
manufacturer’s instructions.
3. Before connecting hoses to the tractor hydraulics, ensure that tractor and machine circuits are not under
pressure.
4. It is strongly recommended that the operator mark the hydraulic connections between tractor and machine
to avoid making a wrong connection. WARNING ! Functions could be reversed (for example : lift/lower).
5. Regularly check the hydraulic hoses ! 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.
