Pfeuffer GmbH expressly points out that fitting spare parts and renewing wearing
parts are procedures which require a certain level of experience!
This work should
only be carried out by a
specialist
if it is not possible to send the FRIABILIMETER to
Pfeuffer GmbH' customer service.
DANGER
Touching live parts can be fatal!
The owner-operator must then ensure that a safety check is carried out according to
DIN VDE 0701-0702 before the FRIABILIMETER is taken back into operation.
CAUTION
Cutting injuries to hands and fingers!
The sheet metal parts of the housing may have sharp corners and edges.

Allow the FRIABILIMETER (motor) to cool down adequately after operation, or
wear protective gloves.
NOTE
Keep all screws and removed small parts carefully.
Metallic housing parts must be connected to the protective earth conductor.
In this connection, make sure that
all original parts are reinstalled in the location intended for them. no excessively
long screws are used, since these can cause short circuits or damage components
inside the housing.
all grounding cables are reconnected and all screws are firmly tightened.
CAUTION
Dust warning
Cereal dust can build up inside the housing.
Check whether inhaling large quantities might lead to irritation or illnesses of the
respiratory passages, and if so then take appropriate measures.
Do not
use compressed air for cleaning, since this will distribute the dust widely
throughout the surrounding area.
Carefully remove the dust with an industrial grade vacuum cleaner.
