1 Intended use
The SA single disc spreader may only be used in accordance with the information
given in this operator's manual.
The SA single disc spreader is constructed in accordance with its intended use
and may be exclusively used for the points listed below:
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
from being used for any other purpose than that specified in the operator's man-
ual.
