3.0 INSTRUCTIONS FOR USE
To obtain the best performance from the equipment, carefully
follow what is set up below.
ATTENTION
All maintenance work, adjustments and preparation for
operation, must be carried out with the power take-off of the
tractor disconnected, the seeder on the ground on its
supporting feet, the tractor not running, the wheels blocked
and the key turned off.
3.1 HYDRAULIC SYSTEMS
Safety measures concerning the hydraulics:
1)
When the hydraulic pipes are connected to the hydraulic
system of the tractor, make sure that the hydraulic systems
of the operating machine and the tractor are not under
pressure.
2) For hydraulic-type functional connections between the
tractor and operating machine, sockets and plugs must
be marked with colours, in order to prevent errors. It could
be dangerous if they were accidently confused.
3) The hydraulic system is under high pressure; due to the
risk of accident suitable auxiliary instruments should be
used when investigating possible leakage points.
4) During road transport the hydraulic connections between
the tractor and the operating machine should be
disconnected and secured on the support provided for the
purpose.
5) Do not use vegetable oils for any reason. These could cau-
se damage to the cylinder gaskets.
6) The working pressures of the hydraulic system should fall
within 100 atm and 180 atm.
System regulation
The hydraulic systems provided come equipped with one-way
flow regulators (Fig. 7) which allow for the regulation of the quantity
of oil during opening or closing, depending on how the regulators
have been installed:
-
Flow from A to B, free;
- Flow from B to A, choked (regulated).
To regulate, loosen the lock nut (1 Fig. 7) and turn the knob (2 Fig. 7).
Once this adjustment has been made, re tighten the lock nut.
WARNING
Make sure that the result of this adjustment does not cause
the rising or descent speed to damage the structure itself.
Never exceed the maximum admissible pressure for the
hydraulic system.
3.2 ATTACHMENT THE TRACTOR
The seeder may be attached to any tractor fitted out with a
three-point universal joint.
DANGER
The attachment to the tractor is a very dangerous phase. Be
sure to follow the instructions carefully throughout the operation.
The correct tractor/seeder position, is determined by placing the
equipment at a distance from the tractor so that the Cardan joint
remains extended by 5-10 cm from its maximum closing position.
At this point, proceed as follows:
1)
Hook the lifter bars onto the pins provided (1 Fig. 8-9) Block
with the snap split pins. Hook the chains to the lifting bars
2) Connect the third upper point (2 Fig. 10); the pin will be blocked
with the appropriate split pin; use the adjusting tierod (1 Fig.
