GENERAL SAFETY RECOMMENDATIONS
Before operating the machine, always ensure that tractor and machine conform with work safety and
road traffic regulations.

6
GENERAL POINTS
1. Inaddition tothe instructionscontained inthis manual,comply with safetyand accident prevention
legislation.
2. Warnings affixedto the machine provideindications on safetymeasures to be appliedand help to
avoid accidents.
3. When driving on public roads, follow the Highway Code in your country.
4. Before starting work, the user must familiarise himself with the machine’s operating controls and
their respective functions. Once work has begun, it will be too late.
5. The user must avoid wearing loose clothing which may get caught up in a moving part.
6. The use of a tractor with a safety cab is recommended.
7. Before switching on the machine and starting work, check around the machine (beware of
children!).Make sure that you have sufficient visibility! Keep people and animals away from the
danger area of the machine (risk of projection!).The machine must be used by one person only.
8. It is strictly prohibited to use the machine to carry persons or animals whilst in operation or transit.
9. The machine must only be hitched to the tractor at the points provided in accordance with the
safety standards in force.
10. When hitching and unhitching the machine, put the stand or stands in the correct position and the
loading device in the inoperative position (arm lowered, grab retracted).
11. Take great care when hitching the machine to the tractor and when uncoupling it.
12. Before hitching the machine, make sure that there is sufficient ballast on the front axle of the
tractor. Ballast should be added to the special supports according to the tractor manufacturer’s
instructions. The front axle load must be not be less than 20% of the unladen tractor weight.
13. Do not exceed the maximum axle weight and the gross vehicle weight rating.
14. Do not exceed the maximum vehicle gauge allowed on public roads.
15. Before entering public roads, make sure that all guards and signalling devices (lights, reflectors,
etc.) required by law are fitted and working properly.
16. All remote controls (cords, cables, linkages, etc.) must be positioned such that they cannot
accidentally set off an operation which may lead to a risk of accident or damage.
17. Before entering public roads, put the machine into the transport position in accordance with the
manufacturer’s instructions (armand grab retracted,bodyin the transportposition, delivery chute
and cover folded back).
18. Never leave the driver’s position while the tractor is running.

24. BEWARE! WHEN CLEARINGA BLOCKAGE, PROTECTIVE GLOVES MUST BE WORN AND
APPROPRIATE TOOLS USED.
25. If cut or injured on contact with the products contained in the machine, disinfect immediately in
order to avoid risks of infection.
26. Steering accuracy, tractor adhesion, roadholding and effective braking are affected by factors
such as the weight and nature of the towed machine, ballasting of the front axle and state of the
land or road. It is therefore essential to apply the degree of care appropriate to each particular
situation.
27. Be extra careful in bends and remember to take account of the overhang, length, height and
weight of the machine.
28. Before using the machine, make sure that the guards are fitted and in good conditions. Damaged
guards must be replaced immediately.
29. Before using the machine, check all screws and nuts particularly those holding the tools (teeth,
forks, blades, knives, conveyor slats, etc.). Tighten up if necessary. Also check drive chain and
conveyor chain tension. Tighten up if necessary. Check the condition of the cover.
30. Do not stand in the working area of the machine.
31. Beware! Crushing and shear zones may exist on remote controlled components, particularly
hydraulically or pneumatically-assisted ones.
32. Before getting down from the tractor or before any operations on the machine, switch off the
engine, remove the key from the ignition and wait until all moving parts are at a standstill.
33. Do not stand between the tractor and the machine until the parking brake has been applied and /
or chocks placed under the wheels.
34. Before working on the machine, make sure that it cannot be started up accidentally.
35. Do not use the loading components (arm, grab, etc.) as lifting gear. Do not stand on these
components.
36. The maximal authorized speed for the machine and the tractor is 25 km/h.

8
HITCHING

position that the lift cannot be activated accidentally.
2. Beware! There is a risk of crushing and shearing in the three-point lifting zone.
3. Only use the tractor hook, yoke or eyebolt to hitch the machine to the tractor.
4. Never hitch the machine to the hole-type drawbar or to the swinging drawbar of the tractor when
taking onto the road.
5. Set the body to the recommended transport height (see table of specifications).
DRIVING COMPONENTS
(PTO and universal drive shafts)
