2.5 How am I warned of hazards?
Hazards are indicated directly on the automatic feeder by safety labels (warning signs, instruc-
tion and prohibition notices), and in the operating manual by specially marked hazard descrip-
tions.
The warnings for hazards that can cause death or injury to people are emphasized more than
those for material damage, for example through the colors, hazard words or symbols used.
Safety labels are an important element of the overall automatic feeder safety concept. They pro-
vide warnings about hazards and explain how to avoid them.

Important safety instructions 13
Make sure that all the specified safety labels are fitted to your automatic feeder and that they
are in a legible condition. If the safety labels are difficult to read, replace them immediately. New
safety labels are available from Förster-Technik GmbH.
2.5.1 What are the components of a hazard description?
A hazard description always consists of the following elements:
• Hazard word (danger, warning, caution, attention)
• Type of hazard (what can happen?)
• Location of hazard (where can it happen?)
• Actions necessary for preventing the hazard (what should I do?).
2.5.2 Potentially fatal hazards or health hazards
Depending on their severity and the probability of them occurring, hazards that can cause death
or injury to people are indicated by a hazard symbol (warning triangle with exclamation
mark) and the following hazard words:
DANGER!
The word DANGER indicates an imminent hazard that will lead to death or serious injury.
Warning signs in the operating manual: DANGER (white text on red background).

2.6 Safety signs
Different safety notices are attached at the hazardous points on the automatic feeder. Warning
signs, prohibition and instruction notices.
What are warning signs?
Warning signs consist of:
• A pictogram in a yellow triangle illustrating the potential hazard.
What are prohibitory signs?
Prohibitory signs have a pictogram of the prohibited action in a red circle with a line
through it. See the adjacent example. They graphically depict the prohibited ac-
tion. In this example, the hose with a line through it means that you may not use
high-pressure cleaners.
What are instruction notices?
Instruction notices show a pictogram of what you are being instructed to do in a
blue circle. They illustrate what you have to do. In the example, the pictogram
means that you must always disconnect the plug first.

2.7 Safety devices
The automatic feeder may only be operated if the safety equipment is complete and intact. The
automatic feeder has the following safety equipment:
• Safety signs (warning signs, instruction and prohibition signs).
• The heater's safety temperature limiter. This shuts down the heater in the event of overheat-
ing (temperature rises above 70°C). The heater may only be reactivated by a service engi-
neer.
• Safety grid for the powder hopper attachment. The safety grid prevents people from being
injured by the rotating tools in the hopper, for example when adding milk powder. It must al-
ways be installed when the unit is operating.
• The scraper next to milk powder discharge. The powder discharge opening may only be
cleaned with the scraper. This prevents finger and hand injuries caused by the powder con-
veyor starting up automatically.
The safety devices at the machine are an important part of the safety concept and help prevent
accidents.
• Do not remove or change the safety devices unless the corresponding safety instructions
have been complied with.
• Put the machine into service only once all safety devices have been fitted and are in the
guard position!

Hygiene 19
3. Hygiene
As a farmer with experience in raising lambs, you understand how unhygienic conditions affect
the health of your lambs. Diarrhea and respiratory infections are frequently occurring infectious
diseases in lambs.
Every sick lamb involves additional costs, for example for veterinarians and medication, and re-
quires extra time for care.
The younger the lamb, the weaker its immune system, and the more prone to infection it will be.
The possibility of infection can never be completely eliminated, but it can be minimized by taking
measures to ensure good hygiene.
Maintaining cleanliness is one important and easy measure that helps prevent infectious dis-
eases.
Through proper cleaning at regular intervals, every lamb-raising business can reduce the risk
of infection for its lambs and save money as a result.
Measures to ensure hygienic conditions save time and money.
What are infections? An infection occurs when germs invade and multiply in a host.
Germs are all around us. However, they are not dangerous until they multiply in great numbers.
The risk of infection increases with the number of germs.
When germs get into your animal feed, such as milk, they can spoil the feed and make it ined-
ible.
When germs attack your lambs, for example from infected feed or other infected lambs, your
lambs can become sick and die.
Both situations result in costs that you can minimize by taking measures to ensure hygienic con-
ditions.
As a farmer, it is your job to identify sources of infection and bring them under control.
So how do you prevent infections? By keeping animals in good conditions, with good drink-
ing water and feed quality and, most importantly, through cleanliness.
Proper cleaning is an important way of ensuring hygienic conditions and also prevents
infections.
If the automatic feeder is not cleaned or is cleaned improperly, germs, which are abundant in
the environment, can enter the nutrient-rich feed and multiply. When they drink the feed, your
lambs can become infected, sick and even die.
Proper cleaning of the automatic feeder reduces the number of germs and therefore the risk of
infection.
The cleaning chapter (see 7. "Cleaning" ) explains how to clean the automatic feeder properly.
The appendix contains a table of suggestions of how to clean the different parts of the automatic
feeder (see 11.2 "Maintenance intervals and activities" ).
