b) PREPARING THE MACHINE FOR FUNCTIONAL TESTS.
At this point remove the stand 1 from seat A (parking position) and bring it to seat B
(transport and working position). To do this you must remove clip 2 and pin 3, move
the stand 1 to position B and fasten it with pin 3 and clip 2.
NB: In this case, as the machine has just been assembled, the description given here
is intended for the functional tests before transporting it and subsequently before
working, but this procedure should be carried out every time you have to attach the
machine to the tractor.
Now connect the ends of hoses 1-2-3 to the tractor hydraulic couplings 4-5-6. By
moving lever 9, hoses 1-2 connected to hydraulic couplings 4-5 control cylinders 7
for opening/closing the machine (double acting). By moving lever 10, hose 3
connected to coupling 6 controls the rake wheel lifting cylinder 8 (single acting).
Note: The drawings of the hydraulic connections and levers are intended to give only
a general idea of their shape and position. Each tractor has its own specific shape and
location of these devices. At this point the machine is ready for its first starting,
which must be done following the procedures described herein.
Make sure that there are no persons within the operating range of the machine, then
move lever 9 to send oil to cylinders 7, which will start to shorten (or extend),
opening the wing of the machine. Once they are completely closed (or opened),
reverse the flow of the oil and have them return to the starting point. Do at least eight
to ten complete opening and closing cycles to expel the air from the cylinders and
from the hydraulic circuit. Close the cycle by making cylinders 7 open again
completely. With cylinder 7 completely open (machine closed), check that the frame
A is pressed tight against the rubber bumper B so that the machine is stable during
transport.
Now move lever 10 to send oil to cylinders 8, which will start to extend, raising the
rake wheels about 380-400mm – 15,5” from the ground. Cylinder 8 are the single-
acting type, therefore their return to the initial position takes place to the effect of the
weight of the rake wheels. As these are small cylinders, four to five complete cycles
are enough to expel the air. Close the cycle by making cylinder 8 extend fully so that
the rake wheels are lifted off the ground. Now the machine is ready to be prepared for
transport. Before beginning the transport see the following point “c”.
