1Introduction
1.1 Intended use
Sample cleaner MLN helps in determining the total dockage (German = Besatz) associated with grain crops
and grading the said crops. The cleaning process largely corresponds to that of a normal cleaning machine.
The proportion of impurities (coarse particles, fine particles, aspiration discharge), that of small grains and
that of quality grains can be determined with the help of a sample at the time of acceptance. This
facilitates the acceptance of quality grains and the targeted exclusion of batches that do not fulfil the
contractual conditions.
Sample cleaner MLN is designed as a portable machine with a power plug.
Private use of the machine is prohibited.
NOTICE This machine was designed solely for the aforementioned purpose.
Using it for any other purpose or modifying it without the written consent of the
manufacturer is not considered to be in compliance with the intended use. The
manufacturer shall not be liable for the resulting damage. Damage caused by such an
unintended use is at the sole risk of the operator.
The machine is allowed to be operated only if it is ensured that all the safety devices
are functional and the system in which this machine is installed complies with the EU
directives.
Cleaning flour, dust and grit is forbidden.
The samples to be used for the correct operation of the machine are provided by the
operator of sample cleaner MLN.
The operator bears sole responsibility for the proper handling of these materials and
the associated dangers.
Hazard notes and instructions for disposal must be provided by the operator.
The sample must be disposed of after the examination.
Intended use includes also the compliance with the Instruction Manual and User´s Guide as well as the
maintenance and servicing conditions, as specified in these Operating Instructions.
These Operating Instructions do not relieve the operating company of the obligation to develop and to
apply independent health and/or safety regulations or safe working processes which are aimed at the
requirements of the overall machine, as well as the obligation to monitor their compliance.

2.3 Operating and hazard areas associated with the machine
Operating area
Ensure a sufficient working height (depending on the body size of the operating personnel) of approx.
60-65 cm. For this, a suitable base frame is necessary so that the operating personnel can access the
collecting pans ergonomically.
Hazard area
The entire area of one metre around the machine is dangerous during adjustment, maintenance and
repair work. The swivelling range of the self-opening door as well as of the filler cap must also be taken
into consideration.
Do not keep any objects around the machine.
