CHAPTER 5
ADJUSTMENT, PREPARATION AND USE
INTRODUCTION
Connection to the tractor is higly dangerous. Take great care and carry out the entire
operation in strict compliance with the following instruction.
Nobody should go near the area between the tractor and the machine.
Check that all warning and danger signs are in place and legible.
Check that the tractor is in good running order. Check the engine oil, gerbox oil, brake
fluid and cooling water levels as well as the tyre pressures.
Refer to the tractor operator’s manual.
CONNECTION TO THE TRACTOR
Connect the machine to the tractor, hitching it to the drawbar bar at point (1). If the
two-point crosspiece is used, lock the equalizers (10) using the optional screws (8)
and nuts (9). Attention: do not use screws (8) if the machine is hitched to the
drawbar. After the machine is hitched, loosen the parking stand (2) and remove pin
(3), then rotate the stand upward towards the back of the machine and insert pin (3) to
hold it in the resting position.
Once this procedure is completed, insert the quick-release coupling (4) into the tractor
socket and open the tap (the lever must be parallel with the line, as shown in the
illustration). At this point, work carefully with the hydraulic distributor to make sure that
the frame is completely lowered, then adjust the height of the tines above the ground.
To change the distance between the tines and the ground, turn screws (6). By rotating
the crank (7), the tilt of the machine relative to the ground is adjusted.

CONNECTING THE CARDAN SHAFT
More detailed information may be found in the cardan shaft manual which, together with this manual, is an
essential part of the accident-prevention documentation.
It is your responsibility to read and comply with this documentation. If information given in this manual should
conflict with that given in the cardan shaft manual, you should follow the instructions given by the cardan
shaft manufacturer.
Fit the cardan shaft and check that the shaft is connected correctly both at the tractor end and at the machine
end. For more details, see the descriptions on the following pages.
If a safety system is provided, this should be fitted to the machine end, not to the tractor end.
During both transport and use, avoid conditions where the cardan transmission shaft is extended to the
maximum. In all working conditions, the telescopic tubes must overlap by at least 1/3 of their length ).
Conversely, when the cardan shaft is contracted to the maximum, there should still be a gap of approximately
50 mm (2") .
Take particular care when connecting the two cardan shaft end forks and make sure that they are fully
secured. This is achieved by inserting the safety pins and bolts (1) in the special slots (2) on the power
takeoff shafts on both the tractor and machine ends.
Aloose shaft could come apart and cause considerable mechanical damage and serious injury to persons.
