off and the tractor blocked in place. Before carrying out the
dosing test, make sure there are no foreign bodies inside the
hopper and the doser.

the type of product selected.
2) Position the required container (A) under the metering unit and
open the spout for product discharge (B, Fig. 29) ...«TEST»
3) Add a small seed quantity (approx. 40 kg) inside the hopper.
4) Calculate the gate opening value, with the help of the Table 2,
on the basis of the type of seed to be used and the quantity to
be distributed.
WARNING: Make sure the correct seeding roller is being used.
5) The seed table is also affi xed to the machine and from this table
it is always possible to calculate approximate seed distribution
quantities. It is, however, always necessary to carry out a sowing
test!
6) Loosen the fastening screw on the gear adjuster ...
7) ... and bring the graded indicator to the required position (de-
pending on the quantity of product to be distributed), by rotating
the adjuster knob (Fig. 30).
8) Once the sowing test has been successfully performed, secure
the fastening screw of the gear adjuster once more.
For the actual metering test, fi t the handle on the gearbox and turn
it as shown in Fig. 31.
The revolutions of the handle correspond to a 1/40 of a hec-
tare.
Prior to the dosing test, it is necessary to perform a few revolutions
in order to load the dosing rollers with product. Unload the product
from the containers and place them back under the dosers. At this
point, the equipment is ready to perform the dosing test.
Next check, using precision scales, the quantity of product collected
and multiply this by 40 in order to obtain the quantity distributed (in
kg./ha). Make any necessary adjustments. Start up the machine,
performing the above mentioned steps in reverse order.
WARNING: after the test, close the spouts (Fig. 32) ...«WORK»
