3.5.2 INDEPENDENT SYSTEM
When the characteristics of the tractor are such that they cannot
guarantee the correct working of the blower, it is necessary to
install a self-contained oleo-dynamic system.
INSTALLATION CHARACTERISTICS
- Oil supply: follow the data in the table in Fig. 31.
OPERATION DESCRIPTION
The multiplier joined to the tractor's power take-off, works a
pump that takes oil from the outside tank to the three-way
regulator. Here, indicated on the manometer, the pressure
required for the motor to work the blower is adjusted (Table 4).
Furthermore, the system is equipped with a safety valve that
allows the blower to continue to rotate from inertia without
suffering breakage or damage, if the circulation were to stop
suddenly.
STARTING UP
ATTENTION:To verify the sense of spin of the taken one of
force of thetractor before grafting the multiplier.
Fig. 32-2) counter-clockwise spin: the group multiplier-pump
can be grafted therefore like supplied;
Fig. 32-1) hour spin: for a corrected operation it is necessary to
invert the spin of the pump (you see pamphlet cod.
G19502670).
With the engine off and the tractor immobilized, connect correctly
the quick-couplings.
Clean and grease the tractor power take-off. (1, Fig. 33).
Connect the multiplier (2) to the machinery power take-off as
shown in Figure 33.
Make sure it is correctly coupled, block the rotation of the multiplier
with the chains supplied (3). Check the multiplier
(RAPP. 1 : 3 = 540 rpm) ----- (RAPP. 1 : 2 = 1000 rpm)
Driving a vehicle with a 540 rpm propulsion, with a power takeoff
of 1000 rpm and an engine rpm correspondingly low is not
permitted. Danger of blower pump breakage. During distribution
do not let the power take-off rpm drop too low. Check the
multiplier oil level and top up if necessary (ESSO SAE W80-90).
Start the tractor and run the system at idle for a few minutes,
bringing constant pressure to the entire circuit in order to avoid
instability of the blower. Bring the blower to the number of revs
corresponding to the type of product to be distributed (Table 4).
It is necessary to check that the number of revolutions indicated
on the equipment is respected. If the minimum rpm is not attained,
inaccuracy of the machine in the distribution can occur, as well
as clogging of the grain tubes. Maintain a constant pressure in
the system during distribution, otherwise uneven distribution may
occur.
When starting up operation, with the oil cold, operate the power
take-off at minimum for several minutes, bringing the entire
system to a constant pressure level to avoid blower instability.
When it is not intended to distribute product, but rather to use
only the equipment to which it is applied, disconnect the pump
and the multiplier from the rear power take-off and replace it
in the special attachment.
