5.6.9 SETTING THE SCRAPERS
CAUTION
Danger of being crushed. Do not put your finger betwe
-
en the scraper and the roller.
Scrapers allow to free the roller from clods.
The first setting is carried out on the roller scraper bar:
•
Loosen nut (2, “Fig. 34”).
•
Loosen nuts (1) until the scraper is at the desired distan
-
ce from the roller.
•
Tighten all the nuts.
The second setting is carried out on the scraper:
•
Loosen nut(4).
•
Bring the scraper(3) close to the roller.
•
Tighten nut (4).

5.6.10 STARTING WORK
DANGER
Before starting the machine, make sure that the safety
devices are in perfect condition.
Never start the machine if there is a suspected mecha
-
nical failure. Contact the technical assistance centre.
Before starting work, get familiar with the control devi
-
ces and their functions.
Check the working area so as to be confident with the
soil and check for any possible excessive slopes. Make
sure that there are no objects in the area that could
be picked up and thrown at a distance. Clear the area
of these objects. Check constantly that there are no
people, children or pets in the working range of the
machine.
Check the rpm rate before engaging the power take-off.
Do not switch the 540 rpm rate with the 1000 rpm one.
It is absolutely forbidden to linger within the range of
action of the machine when this is operating.
It is absolutely forbidden to get between the tractor and
machine while the engine is running and the driveline
engaged.
Never engage PTO when the tractor engine is off. Dan
-
ger of sudden movements when restarting the tractor.
The operator must never leave the driver’s seat when
the tractor engine is on and/or the machine is running.
Disengage PTO when the machine is not used.
Lower the machine to bring the blades close to the ground,
without touching it. Engage PTO. Lower the machine
gradually and bring it into working position. The tractor
power-lift must be completely lowered.
Begin work with the PTO at full rate. Gradually dig the im
-
plement into the ground. Do not depress the accelerator
pedal too much with the PTO engaged. To break up the soil
to the required degree, you must consider several factors,
i.e.:
•
the nature of the soil (medium consistency, sandy,
clayey, etc.)
•
the work depth
•
the ground speed of the tractor
•
optimum machine adjustment
Soil crumbling is obtained at a low tractor ground speed,
with the rear bar lowered and the blades spinning at 300
rpm. Besides holding back the clods already broken up by
the blades, the rear bar also obtains a well levelled and
uniform surface after the soil has been worked. Adjust the
roller (8 Fig. 1) to suit the degree to which the soil must be
crumbled, engage the PTO and begin to move forward with
the tractor, progressively lowering the implement. Cover
a short distance, then check to make sure that the work
depth, soil crumbling and ground levelling operations have
been carried out in the required way.
CAUTION
The speed of the tractor when the machine is opera
-
tion must not exceed 3-4 mph or components could be
broken or damaged.
Always disengage PTO when lifting the machine to pre
-
vent the PTO shaft working at a too big angle (see PTO
shaft instruction manual).
