in winter road maintenance for spreading material that can be delivered by
chute, such as grit (3/5), sand and salt,
in agriculture for spreading granulated fertiliser.
Any use outside these definitions is considered misuse. The manufacturer is not
liable for any damage which results from misuse. The operator bears the entire
risk.
The intended use also includes compliance with the operating, maintenance, re-
pair and servicing conditions prescribed by the manufacturer. Only genuine spare
parts made by the manufacturer may be used as replacements.
The SA single disc spreader may only be used, maintained and repaired by in-
structed and trained staff who are familiar with the characteristics of the machine
and who are aware of the risks.
Important information on the operation and safe handling of the machine is pro-
vided in this operator's manual. The manufacturer also attaches warning notes
and warning symbols to the machine. All such information must be followed when
using the machine.
Moreover, the relevant accident prevention regulations and the other generally
recognised safety, occupational health, and road traffic regulations must be strict-
ly observed when using the machine.
Unauthorized modifications to the single-disc spreader are not permitted. They
will exempt the manufacturer from liability for any damage resulting therefrom.
In the following chapters, the single-disc spreader is referred to as “machine”.
Foreseeable misuse
The manufacturer provides warning notes and signs on the SA single-disc
spreader relating to foreseeable misuse. These warning notes and signs must be
observed under all circumstances in order to prevent the SA single disc spreader

3.5.6 Operation
If the machine malfunctions, stop the machine immediately and secure it.
Have the fault repaired immediately by appropriately instructed and author-
ised personnel.
Never climb onto the machine while the spreader unit is running.
Only operate the machine with the protective grid in the hopper. The protec-
tive grid must not be removed during operation.
Rotating machine components may cause serious injury. For this reason, en-
sure that you avoid any contact between body parts or clothes and rotating
components.
Before setting the application rate, completely close the metering slide if the
machine is equipped with a hydraulic metering slide actuator.
Do not deposit any parts (such as screws, nuts) in the hopper.
Ejected spreading material may lead to severe injury (e. g. to eyes). For this
reason, ensure that nobody is present in the spreading range of the machine.
If the wind speed is too high, stop spreading since the specified spreading
range can no longer be guaranteed under such conditions.
Never climb onto the machine or the tractor when it is situated beneath high-
voltage electrical power lines.

3.6 Use of spreading material
Incorrect selection or use of spreading material may cause serious injury or envi-
ronmental damage.
When selecting the spreading material, inform yourself about its effects on
persons, the environment, and the machine.
Follow the directions of the spreading material manufacturer exactly.
3.7 Hydraulic system
The hydraulic system is under high pressure.
Fluid escaping under high pressure can cause serious injuries and environmental
damage. The following instructions must be observed to prevent danger:
Always operate the machine below the permissible maximum operating pres-
sure.
Depressurise the hydraulic system before any maintenance work. Turn the
tractor motor off. Secure it against reactivation.
When looking for leaks, wear protective glasses and protective gloves at
all times.
In the case of injury in connection with hydraulic oil, consult a physician im-
mediately as severe infections may occur otherwise.
When connecting the hydraulic hoses to the tractor, ensure that the hydraulic
system is depressurised, both on the tractor and the machine side.
Attach the hydraulic hoses of the tractor and the spreader hydraulic systems
only with the prescribed connections.
Prevent any contamination of the hydraulic circuit. Always suspend the cou-
plings in the brackets provided. Use the dust caps. Clean the connections be-
fore joining them.
Regularly check the hydraulic components and hydraulic hose lines for me-
chanical defects, e.g. cuts and abrasions, contusions, bends, tears, porosity
etc.
Even when stored correctly and used within approved load limits, hoses and
hose couplings are subject to a natural ageing process. This limits their stor-
age and service life.
The service life of the hose lines may not exceed 6 years, including a possible
storage time of maximally 2 years.
The date of manufacture of the hoses is indicated on the hose coupling in month
and year
Replace hydraulic hoses if damaged or aged.
Replacement of hydraulic hoses must meet the technical requirements of the
equipment manufacturer. In particular, note the different maximum pressure
ratings of replacement hoses.

ing operation of the machine.
Any maintenance and service work is to be conducted with increased alert-
ness at all times. Work particularly thoroughly and cautiously.
3.8.1 Qualifications of maintenance staff
Welding and work on the electrical and hydraulic systems is to be carried out
by qualified technicians only.
3.8.2 Wear parts
The maintenance and service intervals described in the present operator's
manual are to be strictly adhered to at all times.
Furthermore, the maintenance and service intervals of the supplier compo-
nents must also be complied with. See the supplier documentation for the rel-
evant intervals.
We recommend that you have the condition of the machine checked after
each season by your specialist dealer, paying particular attention to its fixing
components, safety-relevant plastic components, hydraulics, metering parts
(such as metering slide and agitator), spreading vanes and spreading discs.
Spare parts must at least comply with the technical standards specified by the
manufacturer. The technical standards can be guaranteed by using original
spare parts, for example.
Self-locking nuts are designed to be used only once. Always use new self-
locking nuts to fasten components (e. g. when replacing spreading vanes).
3.8.3 Maintenance and service work
Always switch off the tractor motor before any cleaning, maintenance and
service work and when troubleshooting. Wait until all rotating parts of the ma-
chine have come to a standstill.
Make sure that no unauthorised person can start the machine. Remove the
ignition key of the tractor.
Check that the tractor with the machine is correctly parked. Park the spreader
with an empty hopper on level, solid ground and secure it to against rolling
away.
Additionally, secure the lifted machine against falling (e. g. using an axle
stand) if you need to perform maintenance and service work or inspections
underneath the lifted machine.
Before carrying out any maintenance and service work, de-pressurise the hy-
draulics.
Disconnect the power supply before working on the electrical system.
Only open the protective grid in the hopper if the machine has been decom-
missioned.
If you have to work while the PTO shaft is rotating, make sure that nobody is
near the PTO or the drive shaft.

Remove any clogging in the hopper only when the machine stands still and
never use your hand or foot to do it; always use suitable tools for this purpose.
In order to avoid clogging, the hopper may only be filled when the protective
grid is mounted.
Before cleaning the machine with water, steam jet or other cleaning agents,
cover all components that must not get wet (e.g. bearings, electrical connec-
tions).
Regularly check nuts and screws for tightness. Retighten loose connections.
3.9 Safety in traffic
When driving on public streets and roads, the tractor with the attached machine
must comply with the road traffic regulations of the respective country. The owner
and driver are responsible for compliance with these regulations.
3.9.1 Checks before driving
The pre-departure check is an important contribution to road safety. Before every
trip, check compliance with the operating conditions, traffic safety, and the regu-
lations of the country of use.
Is the permissible total weight complied with? Note the permitted axle load,
the permitted braking load, and the permitted tyre load capacity; 13: Axle load
calculation,page 79.
Check the tyre pressures and the function of the tractor brake system.
Is the machine attached appropriately?
Could spreading material be lost while travelling?
- Check the filling level of the spreading material in the hopper.
- The metering slide must be closed.
Does the lighting and marking of the machine comply with the regulations of
your country with respect to driving on public roads? Make sure that warning
signs, reflectors, and auxiliary lights are correctly placed.
