2 Safety information and use
Requirements for the user
2.1
This operating manual is intended for persons assigned with operating
and monitoring the Fritsch PULVERISETTE 2. The operating manual and
especially its safety instructions are to be observed by all persons
working on or with this device. In addition, the applicable rules and regulations for accident prevention at the installation site are to be observed.
Always keep the operating manual at the installation site of the PULVERISETTE 2.
People with health problems or under the influence of medication,
drugs, alcohol or exhaustion must not operate this device.
The PULVERISETTE 2 may only be operated by authorised persons and
serviced or repaired by trained specialists. All commissioning, maintenance and repair work may only be carried out by technically qualified
personnel. Qualified personnel are persons who, because of their education, experience and training as well as their knowledge of relevant
standards, regulations, accident prevention guidelines and operating
conditions, are authorised by those responsible for the safety of the
machine to carry out the required work and are able to recognize and
avoid possible hazards as defined for skilled workers in IEC 364.
In order to prevent hazards to users, follow the instructions in this
manual.
Malfunctions that impair the safety of persons, the PULVERISETTE 2 or
other material property must be rectified immediately. The following
information serves both the personal safety of operating personnel as
well as the safety of the products described and any devices connected
to them: All maintenance and repair work may only be performed by
technically qualified personnel.
Safety information and use
2.2 Scope of application
This operating manual is not a complete technical description. Only the
details required for operation and maintaining usability are described.
Fritsch has prepared and reviewed this operating manual with the
greatest care. However, no guarantee is made for its completeness or
accuracy.
Subject to technical modifications.
The PULVERISETTE 2 mortar mill is used for universal dry and wet
grinding to achieve analytical fineness.
During the synthesis, it is used for mixing or homogenising dry samples,
emulsions or pastes.
It grinds inorganic and organic samples for analysis, quality control or
material testing in applications such as:

2.2.1 Operating principle
Rocks/Soils Plaster, lime, clinker, sand,
cement
As with a hand mortar and pestle, the grinding stock is ground in the laboratory mortar mill under the influence of pressure and friction. Unlike
the hand mortar and pestle, the mortar of the laboratory mortar mill is
driven - the pestle axis is mounted on a rotating bearing and can be
shifted horizontally. The relatively large pestle ensures fast and consistent grinding and crushing of sample material.
Extremely sticky or adhesive material can be ground as a suspension by
adding liquid. The liquid can be added or topped up during grinding.
The grinding probe is picked up by the rotating mortar, scraped from its
edge by a Vulkollan scraper, flipped in a plough-like motion and returned
to the pestle.
In contrast to the usually flat hand mortars, the grinding chamber of the
deep mortar bowl is closed in the laboratory mortar mill and sealed by a
rubber lip, enabling comminution with hardly any loss.
Configurable grinding duration and contact pressure of the pestle ensure
reproducible grinding conditions - while the grinding progress can be
viewed through a plexiglas window.
The extraordinary heavy-duty design of the drive, the pestle guide and all
movable parts guarantee operational readiness throughout the long
service life of the laboratory mortar mill.

2.3 Obligations of the operator
Safety information and use
Before using the PULVERISETTE 2, this manual is to be carefully read and
understood. The use of the PULVERISETTE 2 requires technical knowledge; only commercial use is permitted.
The operating personnel must be familiar with the content of the operating manual. For this reason, it is very important that these persons
actually receive the present operating manual. Ensure that the operating
manual is always near the device.
The PULVERISETTE 2 may exclusively be used within the scope of applications set down in this manual and within the framework of guidelines
put forth in this manual. In case of non-compliance or improper use, the
customer assumes full liability for the functional capability of the PULVERISETTE 2 and for any damage or injury arising from failure to fulfil this
obligation.
By using the PULVERISETTE 2 the customer agrees with this and recognizes that defects, malfunctions or errors cannot be completely
excluded. To prevent risk of damage to persons or property or of other
direct or indirect damage, resulting from this or other causes, the customer must implement sufficient and comprehensive safety measures
for working with the PULVERISETTE 2.
Neither compliance with this manual nor the conditions and methods
used during installation, operation, use and maintenance of the PULVERISETTE 2 can be monitored by Fritsch GmbH. Improper execution of
the installation can result in property damage and thus endanger persons. Therefore, we assume absolutely no responsibility or liability for
loss, damage or costs that result from errors at installation, improper
operation or improper use or improper maintenance or are in any way
connected to these.
The applicable accident prevention guidelines must be complied with.
Generally applicable legal and other obligatory regulations regarding
environmental protection must be observed.

Safety information and use
DANGER!
Explosion hazard!
– When grinding oxidizable substances, e.g. metals or
coal, there is a risk of spontaneous combustion (dust
explosion) if the share of fine particles exceeds a certain percentage. When grinding these kinds of substances, special safety measures must be taken and the
work must be supervised from a specialist.
The PULVERISETTE 2 is not explosion protected and is
–
not designed to grind explosive materials.
n Do not remove the information signs.
NOTICE!
Immediately replace damaged or illegible information signs.
2.6 Protective equipment
n Unauthorised alteration of the PULVERISETTE 2 will void Fritsch's
declaration of conformity to European directives and void the guarantee.
n Only use the PULVERISETTE 2 when it is in proper working order, as
intended and in a safety- and hazard-conscious manner adhering to
the operating manual. In particular, immediately rectify any malfunctions that could pose a safety hazard.
n If, after reading the operating manual, there are still questions or
problems, please do not hesitate to contact our specialised personnel.
Protective equipment is to be used as intended and may not
be disabled or removed.
All protective equipment is to be regularly checked for
integrity and proper functioning.
A hood safety switch (3) is installed to ensure that grinding is interrupted
when the hood is opened during operation.
The laboratory mortar mill will not start when the hood is
open!
