must also be respected.
2. Advice is indicated on the machine, specifying safety recommendations in order to prevent accidents.
3. Before travelling on public roads, the operator must ensure that the machine conforms to 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 driven 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.
8. Machine must only be attached to tractor using means provided and in accordance with current safety

10. Before attaching the machine, ensure that the front tractor axle is sufficiently ballasted.
Ballastis to beplacedonthesupportsprovidedin accordance with instructionsofthetractormanufacturer.
11. Do not surpass the maximum axle load or the overall transport weight as prescribed by the tractor
manufacturer.
12. Do not surpass the maximum transport width authorized by road traffic regulations.
13. Beforetransportingthemachineonpublicroads,ensurethatalllegallyrequiredguardsandindicators(lights,
reflectors ...) are in place and in good operation.
14. All operating controls (cords, cables, rods...) must be positioned so that they cannot be set off accidently,
risking accident or damage.
15. Before transporting on public roads, locate the machine into its transport position as instructed in this

17. Drive speed must be adapted to ground conditions as well as roads and paths.
Always avoid abrupt changes of direction.
18. Precision steering, tractor adherence, road holding and efficient braking are influenced by the type of
implement,weight,ballastof frontaxle,ground orroadconditions. Itistherefore ofutmostimportance tobe
cautious in every given situation.
19. Be particularly cautious when turning corners, paying attention to machine overhang, length, height and
weight.
20. Keep clear of the machine operating area.
21. WARNING ! Danger of crushing and shearing can exist when components are operated by hydraulic or
pneumatic controls.
22. Before leaving the tractor or before adjusting, maintaining or repairing the machine, turn off the engine,
remove ignition key and wait until all moving parts have come to a complete stop.
23. Do not stand between the tractor and the machine unless the hand brake is tight and/or stops have been
placed under the wheels.
24. Beforeanyadjustments,maintenanceorrepairsarecarriedout,ensurethatthemachinecannotbestarted

14. Fit safety cap on tractor PTO.
15. Replace any worn or damaged PTO guards immediately.
Rotation speed ... rpm (American Measure) is also expressed in metric measure : Rotational frequency ... min-1.
Both units are equivalent, for example : Rotation speed 540 rpm equals Rotational frequency 540 min-1.
ROAD TRANSPORT
Dimensions
Depending upon the machine’s dimensions, the user should check with the relevant authority that it can be
transported legally on public roads.
If maximum authorised size is exceeded, the user should act according to the legislation in force regarding
transport of oversize equipment.
Load per axle and gross weight
When transporting the machine or combined machines, check that :
- the tractor’s authorised gross weight as well as the maximum weight per axle is not exceeded.
- In all circumstances, the weight on the tractor’s front axle is never below 20% of the tractor’s unladen
weight. If the case arises, fit front ballast weights.
