Safety instructions – summarised, part 1
Safety instructions
We exclude any claims for damages of any kind for injury to persons and damage to equipment arising from 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 to the European Directives will lose its validity.
Furthermore this will lead to loss of any kind of guarantee claims.
Packing
Please keep the packing material for the duration of the guarantee period, since if you have a complaint and the equipment
is returned in inadequate packing your guarantee claim is at risk.
Transport
Lifting above head height is not allowed.
The PM400 must not be knocked, shaken or thrown during transport. Otherwise the electronic and mechanical components
can be damaged.
Temperature variations
If the PM400 is subjected to high temperature variations (e.g. during air transport) it must be protected against condensed
water. Otherwise there may be damage to the electronic components.
Supplied items
If the supplied items are incomplete and/or there is transport damage you must inform the transporter and Retsch GmbH
immediately (within 24 hrs). Later complaints may possibly be no longer considered.
Ambient temperature
If the temperature drops below or exceeds ambient temperature the electrical and mechanical components can become
damaged and performance data can change to an unknown extent.
Atomospheric humidity
At high atmospheric humidity the elctrical and mechanical components can become damaged and performance data can
change to an unknown extent.
Important instructions
If the values on the type plate are not observed electrical and mechanical components can become damaged.
Serial interface
The serial interface cables must not be longer than 2.5 m.
If the cables are longer this can result in disturbances during transmission of data.
Connecting the power supply
If the values on the type plate are not observed electrical and mechanical components can become damaged.
Opening / closing / emergency unlocking the milling chamber
The emergency unlocking device must not be operated when the machine is running. Disconnect the machine
from the power supply before emergency unlocking. High danger of injury through long, unbraked after-running of
the drive can result. The after-running time of the drive is < 10 secs.
Insertion and clamping of the milling cups in the PM400
Always insert 2 opposite or 4 milling cups. All cups must have the same gross weight.
If loading of the PM400 is unbalanced the machine can generate undesirable vibrations and noises. In this
case switch the machine off immediately and check the arrangement and gross weight of the cups.
Before starting the machine make sure that the milling cup is clamped. Milling cups can be ejected – danger of
injuries and damage to equipment.
Always insert 2 opposite or 4 milling cups. All cups must have the same gross weight.
Use only milling cups of type „C“. This type, in combination with the milling cup holder, is a safety component. If other
types or old milling cups are used in the PM400 this may result in unforeseen danger.
Never leave the milling cup clamping device (3) loose, without clamped milling cups, in the milling cup holder. Danger of
ejection.
