3.6 FOLDING FRAME (ORIETTA-I / ORIETTA-I TC)
The seeder is suitable only for the uses indicated. Any other
use different from that described in these instructions could
cause damage to the machine and represent a serious hazard
for the user.
Regular operation depends on the correct use and adequate
maintenance of the equipment. It is advisable therefore to observe
scrupulously what is described in order to prevent any
inconveniences that could prejudicate proper operation and
duration. It is just as important to keep to what is described in
this booklet since the Manufacturer declines all responsibility
due to negligence and non-observance of these rules.
At any rate the Manufacturer is available to assure immediate
and accurate technical assistance and all that may be necessary
for the improved operation and better performance of the
equipment.
Check that the quick hook-ups are coupled correctly; parts of
the system could get damaged if they are not.
ATTENTION
Oil escaping at high pressure can cause skin injury with the risk
of serious wounds and infection. Call a doctor immediately if
such an incident occurs. Therefore, the installation of hydraulic
components in the tractor driver's cab is strictly forbidden.
All the components of the system should be positioned carefully
to avoid parts being damage during use of the equipment.
3.5.1 DESCRIPTION OF FUNCTIONING
The machine frame is designed so that the side ends that hold
the planting elements can be folded using a hydraulic system
(Fig.15), thus reducing the road.
The hydraulic folding parts of the planter are floating and allow
you to work on ground that is not perfectly flat. The side parts of
the frame, in fact, can move down with respect to the central one
by approx. 7 centimetres (Fig. 16).
They are moved by double-acting hydraulic cylinders,
independently of each other. To adjust the speed of rise and fall
of the side frames it is necessary to adjust the valve located on
each hydraulic delivery pipe, as explained in chapter 3.1. (Fig. 7).
When opening and closing of the folding frame, do not under
any circumstances stand close to the machine.
In order to use correctly the toolbar of the planter, operate as
follows:
1) Hook the planting unit to the tractor three-point coupling using
suitably sized pins equipped with the necessary safety
devices (retainer clips, spring pins, etc.).
2) Connect the planting unit hydraulic pipes to the tractor
distributors (see chapter 3.1).
3) Before switching the machine on, make sure that there are
no people, children, animals or any object that could get in
the way of the machine, and ensure that there is excellent
visibility in the area of operation.
OPENING
4) Unhook the safety pins on the frame (A Fig. 17) and place
them in their relative seats (B Fig. 17).
5) Check that the hydraulic pipes are correctly connected (see
chapter 3.1).
6) Actuate the hydraulic system to open the frame (Fig. 15),
keeping the planter raised from the ground.

CLOSING
7) Activate the hydraulic system to close the frame, keeping the
planting unit raised off the ground and with the seeders
hooked into the raised position.
8) Hook the frame safety pins into their relative seats (A Fig. 17).
9) Discharge the pressure in the hydraulic system and
disconnect the hydraulic pipes.
OPTIONAL
For the movement of the side frames of the planter, on request it
is possible to use two-stage cylinders (Fig. 18). During the lifting
stage of the planter, they allow the three frames making up the
planter to be aligned, so making the end of field manoeuvre
easier.
Each two-stage cylinder has 3 hydraulic pipes (Fig. 18):
a) two pipes for opening and closing the frame;
b) one pipe for opening the second stage of the cylinder.
It would be best if the last mentioned pipe were connected to the
tractor's lifting system, but if this is not possible use a distributor
of the tractor.
