General

Cleaning

Do not clean the MM 400 with running water.

Danger to life through current surge

Use only a cloth moistened with water. Cleaning agents

and solvents must not be used – not for cleaning the

milling tools either.

Maintenance

The MM 400 is maintenance-free. When used properly

no maintenance and setting work need be carried out.

Do not make any alterations to the machine and use only spare

parts and accessories approved by Retsch.

Otherwise the declared conformity with the European

directives by Retsch will lose its validity. Furthermore

this will lead to loss of any kind of guarantee claims.

Wear

The milling tools can become worn, depending on the

frequency of the milling operation and the material to

be milled. The milling cups and ball(s) should be

regularly checked for wear and replaced if necessary.

Wearing parts

These operating instructions do not include instructions for

repair. For your own safety repairs should be carried out only

by Retsch GmbH or an authorised representative (service

technicians).

Checks

Correct functioning of the hood switch must be checked

regularly:

• Switch on the machine with switch E.

• Start milling operation with start button P.

• Lift the hood.

• If there is an opening gap of a few cm the machine is

switched off and F4 appears in the display.

• Cancel F4 with stop button O.

If this switching off function does not take place the MM 400

must be checked immediately by Retsch service.

Distribution or duplication of this documentation, using

or passing on the contents, is allowed only with the

express permission of Retsch GmbH.

Anyone violating is liable to pay damages.
