Handling
Crop kit selection
Selenium has three distinct crop kits with their
respective singulator and ejector: for corn soybean
and edible bean, soybean and cotton and milo.
Choose the specific set for the desired crop according
to the colors of the discs. Table 1 lists the color of
the disk for each crop.
Crop kit mounting
To mount the selected crop kit in the seed meter, it is not
necessary to remove the meter from the mini hopper.
1. Open the meter lid by turning the handle in the
counter-clockwise direction.
2. Turn the disc latch counterclockwise.

3. Mount the crop kit with the Singulator facing inside
the seed meter. After positioning the crop kit, turn
the disc latch clockwise to lock it.

chassis until the Handle locks. Make sure the latch
has closed correctly.
2. Repeat the operations of the Crop kit mounting
topic of this manual.

3. Re-open the mini hopper hatch, in the direction
indicated below, until the end. In this position,
the Mini Hopper will be open, displaying
“OPEN ABERTO”.
Crop exchange
1. Push the mini hopper hatch in the direction
indicated in the following image until the end. In this

Seed meter window
Selenium has a window that
offers the possibility to monitor
the singulation of the seeds in real
time. To open the window, simply
slide it as shown in the side image.
After the singulation check, keep
the window closed.
Maintenance
Preventive maintenance before planting
1. Crop kit::
Check the disc, singulator and ejector. Replace the
crop kit when there is excess wear in any of the
following parts: 3. Powder graphite in the seed meter:
Make sure the meter is well lubricated with
powdered graphite before each planting, if not,
apply powdered graphite in the meter before filling
it with seed.

Check for excessive wear, cracks or holes in the
vacuum seal. If any of the above items are present,
replace the seal.

replace the seal.
4. Graphite in the disc:
Check if the graphite on the back
of the disc (side with the ejector
is worn and, if so, apply J. Assy
Lubricant Graphite Spray to the
entire surface of the disc).

STEP BY STEP
TO REPLACE THE SEAL:
A. Remove the vacuum seal from
the meter lid by pulling it up.
B. First assemble the ends of the
new seal in the meter lid.
C. Fit the entire vacuum seal into the
meter lid by pressing it down.
IMPORTANT:
Always keep the back of the disc well graphited
to achieve a good lifespan of the vacuum seal.

INSTRUCTIONS FOR OPERATIONS | SELENIUM Pneumatic Seed Meter |

Position the disc assembly
horizontally and then
apply J. Assy Graphite
Lubricant Spray over the
entire back surface of
the disc. Wait for it to dry
(disassembling the disc
set is not necessary).
5. Storage:
When not in use, store the crop kit in
its original box for its protection.
6. Cleaning:
When not in use, store the crop kit in its
original box for its protection.
c) The seeds must be correctly lubricated. The use
of dry graphite powder applied on the seeds and
mixed uniformly is essential to make the seeds
move easier inside the meter, reducing skips. 0
d) Make sure that the vacuum pressure is set correctly.
If skips persist increase working pressure until
skips are reduced as much as possible. Then check
that there are no multiples.
e) Make sure the vacuum seal is in good condition.
Troubleshooting
Excess of SKIPS
Skips are characterized by the lack of seeds in the disc
holes. They can be reduced with the following actions:
a) Verify that the crop kit has been selected correctly
(information in the topic Crop kit Selection of
this manual.
b) Check the singulator lobes, see if they are not worn
due to excessive use.
Excess of MULTIPLES
Multiples are characterized by the presence of two or
more seeds in the same disc hole. Its incidence can be
reduced with the following actions:
a) Verify that the crop kit has been selected
correctly (see topic: Crop kit selection).
b) Check the singulator lobes, see if they are
not worn due to excessive use.
c) The seeds must be correctly lubricated. The use of
dry graphite powder applied oi the seeds and, mixed
uniformly is essential to make the seeds move easier
inside the meter. In this way, they will be separated
from each other more easily by the singulator.
d) Make sure that the vacuum pressure is set correctly.
If doubles persist, decrease working pressure until
doublesarereducedasmuchaspossible.Thencheck
that there are no skips.

FOR GRAPHITE APPLICATION IN THE DISC:

Problems with seed spacing
If seeds are not correctly spaced, we recommend the
following actions:
a) Check the seed output of the meter and the seed
tube Debris lodged in its walls can divert the course
of the seeds.
b) Check the traction system. Make sure the system
is in good condition and well lubricated.
c) Try rotating the meter manually. Listen for some
unusual sound or signal as it rotates. If it rotates with
difculty, remove the crop kit looking for debris that
could be making the rotation of the kit difcult.
d) Look for marks or evidence of where the seed is
coming into contact with the seed tube. Make sure the
meter is positioned so that the seed falls in the middle
of the seed tube.
e) Check that the air inlets of the meter are opened
(see pages 4 and 5) to allow free air ow in the meter.
f) Make sure the seeds are correctly lubricated.
The use of the dry graphite powder, applied to the
seeds and mixed uniformly, is essential to make
the seeds move easier inside the meter. Thus, they will
detach from the disk at the correct time.
In case of humid weather, increase the dosage of the
grapithe powder.
g) Decrease the planting speed to check if the problem
is being caused by excessive vibration of the row unit.
h) If you have a seed sensor in the tube, check that
the installation is correct. The sensor must not extend
beyond the inner wall of the tube.
Seed density
If the seed density is not in accordance with the congured,
the following actions can be taken:
a) If the meter is driven by a hydraulic motor or electric
motor, check that the number of holes in the disc is
correctly set in the terminal that controls the motors.
Also check that the displayed density is correct.
b) If the meter is mechanically driven by the planter’s
drag wheel, check in the dosage table if the correct
gears are being used.
Product Disposal
At the end of the lifespan of the equipment, please send
it to any J. Assy Agricultural resale partner nearby or
to the implement assembler. From then on, the disposal
will be carried out by those responsible in an appropriate
manner.
