Low temperatures can cause the empty indicator to respond slowly.
Checking the setting:
1. Allow the spreader to run for about 1 minute with the slide closed.
2. If the slide is now opened, the empty indicator must respond after about
5 seconds.
3. If this is not the case, adjust the empty indicator by 5% in the negative
range, see chapter "4.6 Setting the empty indicator" on page 23.
Autostart
If the motor is diffi cult to start due to heavy loads, start the motor up to
10 times in alternating motor directions. If the agitator does not break free
as a result, the motor is automatically switched off. The following message
is shown in the display: Disc blockage.
14
Danger!
Never open the hopper and never touch the spreading
disc when the drive motor is running.
Switch off the drive motor and make sure that the motor
has stopped before you open the hopper or touch the
spreading disc.
Clearing the blockage:
1. Switch off the motor.
2. Manually turn the spreading disc or empty the hopper.

1. Set the speed according to the spreading chart.
2. Set the casting shovels according to the spreading chart.
17
Operating manual Operating the SuperVario®
3.9 Setting the agitator
Because grasses, in contrast to seeds with a grain structure, have very poor
fl ow properties, the agitator must be adjusted accordingly.
Setting for grasses:
Upper stirring shaft on one side
Lower stirring shaft at a ratio of 2/3 t 1/3
Setting for remaining products:
Upper stirring shaft removed
Lower stirring shaft at a ratio of 1 to 1
Danger!
Do not adjust the stirring shafts if the agitator is installed,
which otherwise could lead to bearing failure on the motor.
1. Remove the hopper.
2. Firmly hold the spreading disc and loosen the agitator by turning to the
right.
Important: Left-hand thread!
3. Install the stirring shaft appropriately.
3.10 Empty indicator
The empty indicator shows when the spreading material in the hopper drops
below a particular fi ll level.
The "Hopper empty" message fl ashes for about 5 seconds on the display.
At the same time, 8 warning signals sound and the red LED on the empty
indicator fl ashes.
To switch off the empty indicator again, briefl y close the slide or switch off the
spreader.

4.12 Spreading width and turning procedure
Reference values for the spreading widths of individual spreading materials
can be found in the attached spreading charts.
If you turn the spreader, please note that spreading material continues to
roll on fi rm surfaces, while on the fi eld it falls directly into the surface soil.
In addition, the fl ow quantities differ from the testing values due to different
vibrations during fi eld use.
26
Operating manual Settings and displays
Turning
1. Put the spreader in the box or put the box over the spreader to catch
the spreading material.
2. Set the speed of the spreading disc, the speed must be the speed used
in practice, due to the suction effect.
3. Weigh out the ejected spreading material at various slide positions until
the suitable slide position is determined.
Determining the spreading width
1. Spread on a fi rm surface.
2. Sweep up and weigh the spreading material.

seeds for grasses and intermediate crops such as mustard, phacelia,
fodder radish and turnip rape. It is produced in three sizes. These differ
in the hopper capacity; 70, 110 and 170 litres. There is a stirring shaft on
the spreading disc that projects into the hopper. This keeps the spreading
material mobile in the area of the application opening. The application
rate and the rotation speed of the spreading disc are infi nitely variably
controlled from the operator's cabin via the control panel. Optionally, a
separate motor drives a slowly rotating agitator which can

Cable not plugged in, motor defective
Adjust the empty indicator, see chapter "4.6 Adjusting the empty indicator" on page 23.
If this does not resolve the problem, please carry out the procedure described in point
"3.11 Adapting the empty indicator to the motor output" on page 19.
Control panel plug not connected to spreader Check plug connections, cables, socket and pins
or cable damage/voltage dip
Check plug connections, cables, socket and pins.
Distance from sensor to magnetic encoder too greatCheck the left/right distance from the sensor, max. 10 mm

Important: After each use, thoroughly clean the spreader with water, and regularly grease the drive motor at the shaft output.
In the universal spreader, the slide setting up to 50 is the same, and only needs to be shifted by one decimal place E.g. 85 is changed to 8.5.
From 50 onwards, the flow rate in the SuperVario® is greater.
