2.11 Description of function
The Vento® II is a pneumatic granulate doser for applying seeds and granulated fertiliser in agriculture.
Precise dosing is achieved using a cellular rotor valve that is driven according to the speed of the vehicle. Automatic
dosing by means of a wheel sensor or GPS receiver is possible. The spreader has an agitator for spreading materi-
als with reduced free-flowing properties. The spreading material is applied by means of an airflow through 8 hoses.

3 Mounting and start-up
Warning!
Risk of injury due to inadequate attachment
If the spreader or hopper tip over, this can cause crushing or other injuries.
•Only mount the spreader on carrier vehicles that have a sufficient load carrying capability.
•Before start-up, make sure that the implement, spreading material hopper and hopper cover have
been correctly attached.
3.1 Implement holder
The Vento® II is supplied mounted on the universal
holder as standard. The mounting is specifically depen-
dent upon the carrier vehicle provided, and must be
adapted to its conditions.
Before operation, check the attachment of the spread-
er on the universal holder. The attachment must be se-
cured with the safety bolts (1). If replacing them, use
M10 bolts with a strength class of at least 8.8, with self-
locking nuts.
Optionally, installation is possible using U-brackets
(2) on a square tube with dimensions 80×80 mm to
120×120 mm.
3.2 Install the control panel
Install the universal holder supplied in the package in the working range of the driver.
The installation is specifically dependent upon the carrier vehicle provided, and must be adapted to its conditions.
Advice
Select the installation position so that the accessibility of other controls is not adversely affected.
1. Secure the universal holder to the vehicle using
point (1) and (2).

ed
2. Thread the battery connection cable (6) through the
opening (3).
3. Secure the battery cable plug (4) to the holder (5).
3.3 Install the electronic linkage control (EHR)
1. Secure the sensor in the joint area of the lower
link.
2. Secure the magnetic encoder to the lower link.
3. Set the position of the sensor and the magnetic
encoder.
Maximum distance 8 mm.
Advice
Please note that the contact
surfaces (1) of the sensor
are only located on the left
and right sides.
Sensor inactive
The sensor must not be within range of the magnetic encoder.
Sensor active
The sensor must be within range of the magnetic encoder.
Signal from linkage control
The "active" signal can be output during raising or lowering. Check the correct setting see "Electronic linkage control
(EHR) function".

Mounting and start-up

3.4 Installing hoses
Advice
Route hoses with as few bends as possible, and with the largest possible bending radius.
Incorrect hose routing can result in blockages in the hose.
Only insert clean hose grommets into the holder.
Installing hose
1. Install the sealing ring (1) on the hose grommet.
Ensure that it is correctly seated to avoid capacity
losses.
1. Secure the hose grommet (2) to the hose.
2. Slide the hose grommet (2) into the mounting (3) un-
til it engages.
3. Route the hose and cut to length.
4. Cut the hose off with a straight end.
5. Secure the baffle plate to the hose using a hose clip
(see detail illustration).

3.5 Electrical connection
Caution!
Risk of short-circuit and injury when working on the battery and electrical system!
Electrical current flowing through the body can cause cramps, ventricular fibrillation,
heart stoppage and internal burns. Risk of burns due to arcing caused by short circuits.
•Protect the battery against damage and moisture.
•Disconnect the electrical power supply before starting work on the battery and electrical system.
•Use suitable tools so as to avoid short circuits.
•Sure that the cables are routed without tension, kinking and chafing, and also avoid bending them
around sharp edges.
•During all work on the battery, please comply with the regulations of the vehicle manufacturer in
question.
•Only use original cables, or ones approved by the manufacturer.
•Always push on the cap and lock it to protect electrical connections against damage.
Advice
Faulty cables or cables with incorrect dimensions can lead to malfunctions and damage to the spread-
er. Any changes to cable or plug connections without factory approval automatically invalidates the entire
warranty.
Changes to cables undertaken by the customer are taken into account in the case of repair. Only use original ca-
bles, or ones approved by the manufacturer. You must consult with the manufacture before carrying out any cable
modifications. Power loss must be taken into account when extending cables. A poor power supply may prevent you
from achieving the desired blower speed. Also, this could lead to intermittent complete failure.

Mounting and start-up
14 / 74 1.0 Vento® II
3.6 Connect the control panel
1. Connect the signal cable (2) on the electronic link-
age control to the 7-pole socket (1).
2. Connect the control cable (4) on the spreader to the
multi-pole socket (3).
1. Place the control panel plug into the socket (1) on
the supplied battery cable.
2. Connect the connector (2) on the black cable to the
negative pole on the battery (not to the bodywork).
3. Connect the connector (3) on the red cable with the
fuse (4) to the positive pole on the battery.
Advice
•Use the supplied 6 mm² battery cable to ensure a perfect power supply.
•A poor power supply may prevent you from achieving the desired blower speed. Also, this could lead
to intermittent complete failure.
Any changes to cable or plug connections without factory approval automatically invalidates the entire warranty.
Changes to cables undertaken by the customer are taken into account in the case of repair.
The spreader is ready for use.
3.7 Adjust the empty indicator
The empty indicator is given a default setting at the factory.
If you use particularly lightweight spreading material, it may be that the sensitivity of the empty indicator has to be
adjusted.
Adjust the empty indicator:
1. Turn the red setting screw clockwise.
This increases the sensitivity of the empty indicator.
2. Turn the red setting screw anti-clockwise.
This reduces the sensitivity of the empty indicator.

3.8 Filling the Vento® II
Warning!
Risk of injury during operation if the spreading material hopper is open, due to spread-
ing material being thrown out and rotating parts.
This can cause injuries to the eyes and crushing injuries.
•Only operate when the hopper cover is closed.
•Always switch off the spreader and blower before opening the spreading material hopper.
Warning!
Risk of injury!
•Wear appropriate working and protective clothing during all work.
•Comply with the regulations of the fertiliser manufacturer.
Advice
Attach the data sheet of the fertiliser used in a clearly visible position on the spreader.
Advice
Make sure that no foreign bodies (e.g. packaging material) get into the hopper, in order to avoid malfunc-
tions.
Before starting, ensure that the hopper on the Vento® II is completely secure.

Filling
1. Make sure that the spreader and blower are
switched off.
2. To fill the spreader release the rubber straps (2) on
the hopper and remove the cover (3).
3. Make sure that suitable rotary valves are fitted ac-
cording to the spreading material table, and that the
load relief roof of the agitator has been mounted cor-
rectly.
4. Fill the spreading material, making sure that no for-
eign bodies or impurities get into the hopper.
5. Before closing the hopper, make sure that the
seal is in place all round between the hopper
and the hopper cover.
6. Seal the hopper using the four rubber straps (2).
