5. Description of the machine
5.1 Functional description
The drive shaft powers a compressor which generates negative pressure (vacuum) in the tank container.
By connecting a suction hose to the quick coupler, the slurry can be sucked into the tank by means of the negative
pressure. A siphon and additional siphon prohibit over-suction in the slurry tank, thereby preventing contamination of the
compressor during the suction process. The filling speed can be increased with a turbo filler. The slurry is discharged by
means of the positive pressure, which is also generated by the compressor. The pressure relief valve (compressor) is
configured at the factory. The valve is factory-sealed to prevent manipulation of the setting. It stops the pressure rising
above the permissible value of 0.5 bar. A positive/negative pressure relief device is located at the top of the tank as
standard.
For large spreading widths, the output can be increased with the aid of a discharge accelerator.
To prevent excessive sloshing during travel, baffle plates are used in the vacuum tank.
5.1.1 Suction process
Suction: When the compressor is set to suction position, negative pressure is created in the tank container.
The resulting vacuum causes the substrate to be sucked into the tank.
In combination with the foam separator, the siphon prevents over-suction of slurry into the compressor.
5.1.2 Discharge process
Discharge: When the compressor is set to pressure position, air flows into the tank container.
The resulting positive pressure causes the substrate to be pressed into the spreader.
A pressure relief valve ensures that a maximum pressure of 0.5 bar is not exceeded during discharge.

All trailers are in basic condition. The weight specifications comply with German traffic laws (StVZO). It is possible that different vehicle class
provisions exist in different countries. The mass figures are version-specific and may deviate.
Details are provided on the type plate, for instance. The weights and drawbar loads were partially determined by calculation and may differ in
practical applications. The centre of gravity and thus the drawbar load may shift depending on how the load is distributed.
If additional devices are used, the payloads, empty loads and axle loads will change.

8.9 Installing forced steering on the towing vehicle (optional)
The customer mast adapt the forced steering individually to each towing vehicle. This means that the settings must be re-
adapted every time the towing vehicle is changed.
The dimensions on the Ø 80 ball head coupling and the clearances according to ISO 500 and ISO 730 must be applied.
Procedure
Mounting of the steering cylinder at the same axial and
vertical height as the ball head coupling on the towing
vehicle (tractor) with 250 mm clearance (

5).
Fig. 26:Installation layout for forced steering
- At maximum steering angle, the tyres must not touch the frame or other parts of the vehicle.
- Check the axle stops and adapt them to the tyre size if necessary.
- At maximum steering angle of the hydraulic cylinders with coupling (52°), ensure sufficient space from the panelling on
the outside and from the flange coupling on the inside.
- The cylinder protection (on the side of the traction bar) must be checked and adjusted for every towing vehicle type; if
necessary, double the cylinder protection until the wheels of the towing vehicle (tractor) make contact at maximum
steering angle.
Attention! The stopcocks on the steering axle must be opened before commencing travel, otherwise
the hydraulic cylinders may be damaged.
When coupling the towing vehicle to the trailer, approaching in exactly the same position as when uncoupling will not
work. The forced steering can therefore be re-coupled as follows.
Procedure
- Approach the trailer with your towing vehicle as straight as possible.
- Couple the towing vehicle to the trailer via the trailer coupling.
- Release the lock at the end of the forced steering cylinders by lifting up the lever.
- The cylinder can now move freely and can be easily connected to the towing vehicle.
- Fold the lock lever back down again.
- Drive the tractor/trailer combination forwards slowly until the vehicles are in a straight line. The forced steering
cylinder lock should re-engage during this process.
The tanker is delivered with the stopcocks on the steering axle closed. They must be opened before
commencing travel, otherwise the hydraulic cylinders may be damaged.
Setting up the system
1. Open stopcocks 1, 2 and 3
2. Drive the tractor/trailer combination forwards slowly until the vehicles
are in a straight line
3. Apply a pressure of 50 bar to the system
4. Close stopcock 1

Attach the drive shaft between the tractor and the vacuum
tanker.
Ensure that the swivel head audibly engages in the PTO stub.
Fig. 33:Attaching the drive shaft
Before assembly, check the minimum length of the drive shaft. The minimum length is the smallest
possible distance between the tractor PTO and the connection point on the trailer. An excessively long
drive shaft can buckle during operation or even break off. You must also read the drive shaft
operating manual carefully and follow the contained instructions.
9.1.3 Conducting a trial run
After the machine is set up and prepared and before work begins, a trial run must be conducted in unloaded condition.
Procedure
- Turn on the machine as specified
- Perform all functions of the machine individually.
Coupling:
1. Yellow –brake line
2. Red –supply line
Uncoupling:
1. Red –supply line
2. Yellow –brake line

9.2 General safety and operating instructions
The following section contains some general notes on safety and operation for working with the tank trailer, repeated and
summarized together for better clarity:
- In addition to the information in these operating instruction, you must also observe the generally applicable safety and
accident prevention regulations.
- Attachments must only be used if all safety devices are in place and in the protective position.
- Before starting work, you should familiarise yourself with all devices and controls as well as with their function. It is too late to
do so once work has started.
- When handling slurry, be aware that the gases produced are highly toxic, and explosive when combined with oxygen. Naked
flames, light testing sparks, and smoking are therefore forbidden.
- During flooding or alternate flooding operations, particular care should be taken due to gas formation in the area of the open
valve to the trough mixer, or main container or cross-channels, as well as at the stirring and removal positions when the
agitators or pumping stations are active.
- Always ensure sufficient ventilation and/or air supply when working with slurry.
- Only perform maintenance work when the containers are empty.
- The weights and loads specified on the type plate must be observed.
- Never park tanks on the supporting mechanism when loaded.
- The drive shafts must meet the requirements of the attachment manufacturer.
- Do not stand on the drive shaft.
- Do not enter the work area while parts (drive shaft) are still rotating.
- Before first-time start-up, move all protective devices to the safety position.
- There must be no persons in the danger zone (suction nozzle) during slurry application/filling.
- Leave all gate valves open during storage in winter. Risk of frost damage!
- The compressor must not be overheated.

9.6 Operation via tractor control units
If the tanker does not feature a hydraulic control block, all functions are operated directly via tractor
control units.
Summary of tank functions with pressure sequence valve:
If a pressure sequence valve is installed, the following 3 functions can
be controlled with one tractor control unit:
Suction nozzle UP/DOWN
Suction nozzle valve
Compressor changeover
Fig. 38:Hydraulic connection / pressure sequence
valve
Using the existing stopcocks, you can preselect whether one of these
functions is to be performed individually when actuated via the tractor
control unit, or whether all functions are to be carried out consecutively.
Fig. 39:Stopcocks
The functions are performed consecutively when the required pressure is reached.
If oil pressure is applied in direction 1 on the tractor control unit (all
stopcocks open on the pressure sequence valve), the functions are
carried out in the following order:
1. Hydraulic compressor changeover switches to suction.
2. The suction nozzle lowers itself.
Fig. 40:Hydraulic connection
Fig. 41:Hydr. compressor changeover
Fig. 42:Suction nozzle

3. The suction valve opens.
If the double-action control unit is operated in the other direction
(direction 2), the functions are performed in reverse order.
Fig. 43:Suction nozzle / suction valve
9.7 Operating the turbo filler
9.7.1 Operation via tractor control unit
An oil flow rate of approx. 80 l/min is required to operate the turbo
filler.
The hydraulic connections must be attached to the tractor as follows:
Connection 1: Supply (small hose diameter)
Connection 2: Return (large hose diameter)
The turbo filler can be activated or deactivated directly via a stopcock in
the system,
provided that the required oil flow rate exists.
Fig. 44:Turbo filler
Fig. 45:Hydraulic connection
Connection 2 must be attached to a pressureless port on the tractor.
