machine is used according to the intended purpose with a
knowledge of this technical documentation it is completely
safe and reliable to operate.
Safety instructions
As the operating authority it is your duty to ensure that all
persons charged with working on the PP40:
have read and understood all the instructions on safety,
from the beginning of work know all the instructions and
regulations for the target group relevant to their work,
have access to the technical documentation for this machine
at all times without problems.
New personnel should be familiarized with safe, proper
handling of the machine before beginning work on the PP40,
either by verbal instruction from a competent person or
through this technical documentation.
Improper operation can cause injury to persons or damage
to the equipment. Your are responsible for your own safety
and that of your employees.
Ensure that no unauthorized persons have access to the

Safety instructions – summarised, part 1
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.
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 declared by Retsch will lose its validity.
Furthermore this will lead to loss of any kind of guarantee claims.
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.
The PP40 must not be knocked, shaken or thrown during transport. Otherwise the electronic and mechanical components
can be damaged.
Lifting above head height is not permitted.
If the PP40 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.
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.
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.
At high atmospheric humidity the electrical and mechanical components can become damaged and performance data can
change to an unknown extent.
If the values on the type plate are not observed the electrical and mechanical components can become damaged.
Only a qualified electrician should carry out electrical connection. Danger through current surge.
If your mains connection for the PP40 includes a fault-current protective system, fault throwing may result through the antiinterference wiring of the frequency converter when this is switched on (switching on takes place each time the pressing
chamber hood is closed).
If the values on the type plate are not observed this can result in damage to the electrical and mechanical components.
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.
If the values on the type plate are not observed the electrical and mechanical components can become damaged.
The emergency unlocking device must never be operated when the machine is running – only when the machine is at a
standstill and is disconnected from the mains supply.
Danger of injury through pressing.
Use only the specificated pellet press ring size.
Mechanical components can become damaged through using wrong ring sizes.
Please take necessary measures, depending on the dangerous nature of your pressing material, to avoid danger to persons.
Check the quality of the press rings regularly.
Damaged rings can cause a damage to press tool.
The filling quantity shall be 8 – 12 ml.
The rings and press tool used could otherwise become damaged.

Pellet press ring filling level
If the filling level of the pellet press ring is too high or too low the pressing result will be impaired.
Please take such measures in accordance with the hazardousness of your sample material as to avoid any possible danger
for persons coming into contact with it.
To avoid analyses falsifications, the upper and bottom punch (press tool) must be cleaned after each press process, by using
a soft cloth and a vacuum cleaner.
For press ring ø40/35x14 the pressing force is limited to 20 t. (A higher pressing force can cause a deformation of the ring
and a destruction of the pellet).
Even though starting without the lid closed is not possible, make sure that the lid is closed before you start the machine
unattended.
Do not clean the PP40 with running water.
Danger to life through current surge.
Use only a cloth moistened with water.
Solvents are not permitted.
Easy running of roller 1 on the closing pin is necessary for reliable closing via the automatic closing mechanism of the PP40.
These operating instructions do not include repair instructions. For your own safety repairs should be carried out only by
Retsch GmbH, an authorized agent or service technicians.
