2 Safety
2.1 General information on safety
The chapter Safety contains basic safety instructions and
provides an overview of all important safety aspects. Further
task-related safety instructions are included in the paragraphs
about the individual phases during the life cycle. Adherence
protects your own safety.
2.2 Correct use
The self-propelled fodder mixing wagons of the Sherpa series
are designed for removal, charging, chopping, homogeneous
mixing, transport and discharge of all types of silage and
normal fodders used in keeping livestock.
Prerequisites:
•In conventional TMR mixtures*, the dry substance
content of the total mixture must be more than 30 % at
any time of the mixing process.
•Use a protective cover if the dry substance content is
less than 30 % at any time, e.g. in compact TMRs.
The fodder mixing wagons are only allowed to be filled by
means of the following vehicles and equipment:
•Pick-up arm
•Hydraulic feed hopper at the mixing container (optional
extra)
•Tractor with front loader
•Yard or wheeled loader
The machine is only allowed to be operated by one person.
The following is also part of the correct use:
•The observance of all instructions contained herein,
•the observance of the specified service and maintenance
work on the machine,
•the exclusive use of original spare parts.
Any use beyond the above is prohibited and will be regarded
as incorrect.
The user will be solely responsible for any damage resulting
from incorrect use; the manufacturer will not assume any
liability.
* TMR = Total Mixed Ration

Safety
Sherpa 120, 140 | 06.19 17
2.3 Reasonably foreseeable misuse
The following points describe a reasonably foreseeable
misuse of the machine:
•Participation in road traffic with overloaded machine
•Dropping of large fodder quantities into the mixing
container from an excessive height
•Removal of stuck fodder from the charging tools at the
container (container top edge or overflow ring)
•Long interruption of the mixing process with the mixing
container heavily filled
Long interruptions cause large "breakaway torques" and
thus a strong load exerted on the power train.
•Dosage of the fodder quantity to be discharged by means
of the conveyor speed with the discharge gate completely
open
•Entry into the mixing container via the ladder and over
the top edge of the container
•Use of machine covers as platform
•Use of pick-up arm as lifting device

Safety
18 Sherpa 120, 140 | 06.19
2.4 Safety-conscious working
Observe as the basic prerequisite for safe working:
•All specified safety and warning information as well as
the instructions in these operating instructions
•Instructions regarding correct use
•Warning signs on the machine
•General national occupational safety, accident prevention
and environmental protection rules
•National road traffic regulations for transport journeys
•Operation of the machine only in a sound safety-related
condition
•Wearing of personal protective equipment
•Make sure that third parties and animals leave the
hazardous area before operating the machine.
Particularly be aware of children.
•Never carry passengers, animals or objects on the
machine.
2.5 Technical alterations
You are only allowed to carry out technical alterations,
extensions or modifications on the machine with the prior
written consent of the manufacturer.
The manufacturer will not assume any liability for damage
resulting from:
•Unauthorised alterations of the machine
•Use of non-approved parts
•Welding and drilling work on load-bearing parts of the
machine
In case of non-observance, the declaration of conformity and
the CE symbol of the machine will become invalid.
Furthermore, the operating license according to national and
international regulations will become invalid.

Safety
Sherpa 120, 140 | 06.19 19
2.6 User’s obligation
The user himself is responsible for observance of the binding
laws, rules, applicable local provisions and national
regulations.
The user is obliged
•to exclusively have staff working with and on the machine
who have been instructed how to operate the machine
and possess the minimum qualification.
•to provide the necessary personal protective equipment.
•to keep all warning signs attached to the machine in
legible condition. Immediately replace missing or
damaged warning signs.
2.7 Operator’s obligation
Any people charged to work with and on the machine are
obliged
•to acquaint themselves with the machine before starting
work.
•to observe the general national occupational safety,
accident prevention and environmental protection rules.
•to adhere to the instructions in these operating
instructions.

Safety
20 Sherpa 120, 140 | 06.19
2.7.1 Staff requirements
The different tasks described in these operating instructions
place different requirements on the qualification of the people
entrusted with such tasks.
Inexperienced and insufficiently qualified members of staff are
not able to evaluate the risks associated with the handling of
the machine, thus endangering themselves and other people.
•Only trained and instructed members of staff, who have
been informed about the risks, are allowed to carry out
the work.
•Members of staff to be trained must be supervised by
experienced qualified staff members when working on
the machine.
•Only people expected to reliably carry out the work, are
allowed to carry out such work.
•Only authorised workshops are allowed to carry out work
requiring special expert knowledge.
Unless otherwise provided by law, the admissible members of
staff, their minimum qualification and their deployment after
the machine's life cycle are specified. See the following table:
