1Introduction
1.1 Intended use
The Vario sample divider is used for dividing up samples of grain-like crops (agricultural seed) into sub-
samples. The division procedure is used for achieving representative sub-samples.
The Vario sample divider is designed as a portable machine with a power plug.
Private use of the machine is prohibited.
NOTE The Vario sample divider was designed solely for the aforementioned purpose.
Using it for any other purpose or modifying it without the written consent of the
Pfeuffer GmbH is not considered to be in compliance with the intended use.
The Pfeuffer GmbH shall not be liable for the resulting damage. Damage caused by
such an unintended use is at the sole risk of the operator.
The sample divider is not suitable for the division of
•flour, dust and grit
•liquid, sticky and oily products
•objects made of metal, stone, concrete, plastic or other foreign components.
The Vario sample divider 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.
The samples to be used for the correct operation of the Vario sample divider are
provided by the operator.
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.
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.

The Vario sample dividers 1G, 2H, 4-8 are used for evenly dividing all grain-like crops.
Set the division ratio on the adjustment lever and fill the sample into the filling funnel.
The machine starts up when you set the operating switch to ON. The rotating distributor arm turns and
passes the eight variably adjustable sample chambers. The partial samples reach the collecting pans
alternately via a system of pipes (In the Vario 1G through a funnel).
The surplus sample material flows through the middle and can be collected in a large collecting pan.

Installation and commissioning
Revision 4 | Operating instructions sample divider Vario 19 | 34
6Installation and commissioning
The chapter Installation and commissioning is intended for skilled personnel only.
6.1 Positioning of sample divider
Unpack the sample divider carefully (refer to chapter 4.4) and place it horizontally.
Ensure a working height of approximately 60-65 cm, depending on the size of the operating personnel.
A correct horizontal positioning of the machine guarantees an even division of the grains.
Check if all the components are firmly secured.
Re-tighten all the screws and clamps.
CAUTION
Unexpected automatic start of the sample divider!
If the operating switch is activated (ON position) and there is a periodic power supply,
the sample divider starts up automatically.
Keep the operating switch in the OFF position, before connecting the sample
divider to the electrical power supply.
Insert the mains plug into a correctly-earthed socket with an earth conductor.
Activate the sample divider keeping in mind all the specifications given in chapter 7.

7.1.2 Adjustment lever division ratio
With this lever, the division ratio is adjusted based on the yellow scale.
7.2 Settings
The Vario sample dividers have 8 outlets and one surplus outlet. 8, 4 or 2 outlets are grouped together
for the sample depending on the model:
Model 1G8 8 outlets for a sample
Model 2H 4 outlets per sample
Model 4-8 2 or 1 outlet(s) per sample
7.2.1 Dividing time
The distributor arm of the sample divider turns at a speed of 40 rpm (revolutions per minute) in the
dividing process. This means one rotation takes about 1.5 seconds (s). In each rotation, the eight outlets
are passed over/loaded once.
In order to obtain a representative partial sample, it should consist of at least 40 individual samples. This
means the following minimum dividing time must be observed for the various models:
Model 1G8 40 individual samples = 8 x 5 rotations 5 x 1.5 s = 7.5 s
Model 2H 40 individual samples = 4 x 10 rotations 10 x 1.5 s = 15 s
Model 4-8 40 individual samples = 2 x 20 rotations (4 samples) 30 s
1 x 40 rotations (8 samples) 60 s
