2. Starting up the SuperVario®
2.1 Mounting the frame
The SuperVario® can be screwed on directly or attached by means of
an auxiliary bracket.
Mounting holes are provided on the back of the frame.
The delivery height can be found in the spreading charts (1.00 - 1.30 m).
The SuperVario®canbeattachedtothefrontorrearofatractor,o󰀨-road
vehicle, ATV or soil cultivation equipment. Because the SuperVario® is
considerably heavier with a full hopper, check the load capacity of platform
gates and other consoles.
2.2 Electrical connection
Technical data
Operating voltage 12 to 15 V
Fuse 25 A
Motor output 300 W
Speed range 200 to 3000 rpm
Power consumption of motor At start, up to 25 A;
normal operation up to 18 A
Operating temperature -10 to +70 °C
Storage temperature -30 to +70 °C
Weight of SuperVario® 70/110/170 31.5/33/35 kg
Any changes to cable or plug connections without factory approval
automatically invalidate the entire warranty. Changes to cables are
automatically charged in the event of repairs.
You must consult the manufacturer before carrying out any cable
modications.
Power loss must be taken into account when extending cables. A poor power
supply may prevent you from achieving the desired speed. Also, this could
lead to intermittent complete failure.

2.4 Mounting the control panel
Caution!
Ensure that the cable is not routed over
any sharp edges.
Important!
Make sure that you use only the battery cable supplied.
1. Mount the support for the control console in the vehicle cab.
2. The supplied battery cable must be installed, even if there is a socket
available, as our battery cable is 4mm².
Connect terminal 2to the negative terminal of the battery (not to
the bodywork).
Connect terminal 3(with fuse 4) to the positive terminal of the bat-
tery. Run the end of the cable with the socket into the carrier vehicle.
3. Plug the spreader cable into the 16-pin socket of the control panel.
Your device is now ready to operate.

Low temperatures can cause the empty indicator to respond slowly.
Check the setting:
1. Let the spreader run for approx. 1 minute with the slide closed.
2. If the slide is now opened, the empty indicator must respond after
approx. 5 seconds.
3. If this does not happen, set the empty indicator in the negative
range by 5%; see section “4.6 Adjusting the empty indicator” on
page 21.

Check the mechanical clearance of the slide and perform the reference
run again.
3.8 Setting the spreading width
The spreading width depends on the condition of the spreading material
and the speed of the spreading disc. The more coarse the spreading material,
the larger the possible spreading width.
1. Set the speed according to the spreading chart.
2. Set the casting blades according to the spreading chart.

3.9 Setting the agitator
Because grasses, in contrast to seeds with their grain structure, have very
poor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 or 1/3
Setting for remaining products:
Upper stirring shaft dismantled
Lower stirring shaft at a ration 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 turn the agitator to the right.
Important: Left-hand thread!
3. Appropriately install the stirring shafts.
3.10 Empty indicator
The empty indicator indicates when the spreading material in the hopper drops
below a certain level.
Themessage"Hopperempty"ashesonthedisplayforapprox.5seconds.
At the same time, 8 warning signals sound and the red LED on the empty
indicatorashes.

Danger!
The drive motor starts immediately when switched on.
Make sure that no-one is in the danger area when you
switch the system on.
PressandholdtheOn/O󰀨buttonforabouteightseconds.
Machine starts the calibration automatically. The spreading disc rotates for
30 seconds at maximum rpm. It then falls very slowly to 0 rpm. The parame-
ters are stored in the controller.
Calibration takes three minutes.
During calibration of the empty indicator, the following message appears
on the display.
Error FLP = PWR
Thespreaderswitcheso󰀨automaticallyoncecalibrationiscompleted.
Calibration of the empty indicator has been successfully completed.
It is now possible to spread by restarting the machine.
