Safety instructions
We exclude any liability for claims for damages in any form whatsoever for injury to persons or damage
to the machine caused through non-observance of the following safety instructions.
Use according to the intended purpose
Do not make any alterations to the machine and use only spare parts and accessories approved by
Retsch. Otherwise the Declaration of Conformity with European directives made by Retsch will lose its
validity. Furthermore this will also lead to the loss of any guarantee claims.
Please keep the packing material for the duration of the guarantee period, since, in case of a complaint
and return of the machine in unsuitable packing material your guarantee claim will be at risk.
The MM 400 must not be jolted, shaken or thrown during transport. Otherwise the electronic and
mechanical components may be damaged.
If subjected to high temperature variations (e.g. during transport by aircraft) the MM 400 must be
protected against condensed water. Otherwise the electronic components may be damaged.
If the delivery is incomplete and/or transport damage is found, you must inform the transporter and
Retsch GmbH immediately (within 24 hrs). Later complaints may possibly be no longer considered.
Conditions for the place of installation
If the temperature drops below or exceeds the ambient temperature the electronic and mechanical
components may be damaged; the performance data are then altered to an unknown extent.
At high atmospheric humidity the electronic and mechanical components may be damaged and the
performance data are altered to an unknown extent.
If the values on the rating plate are not observed the electrical and mechanical components may be
damaged.
Inserting / replacing the milling cups
Ensure that the milling cups are inserted correctly in the milling cup holder – otherwise they can become
damaged when starting the machine.
Both milling positions must always be used since otherwise this will cause considerable unbalance.
When removing and opening hot milling cups always wear protective gloves.
Danger of burning the hands.
Observe the relevant regulations and directives of your country for handling chemicals and hazardous
materials.
Apply these when working with the MM 400.
Milling of materials with the MM 400 which give a risk of fire or explosion is prohibited.
Please take the necessary measures, depending on the hazardous nature of your sample, to prevent
danger to persons.
Note also that the properties, and therefore the hazardous nature of your sample, can change during the
milling process.
