Safety informaon and use
2 Safety informaon and use
2.1 Requirements for the user
This operang manual is intended for persons assigned with operang and mon-
itoring the Fritsch PULVERISETTE 11. The operang manual and especially its
safety instrucons are to be observed by all persons working on or with this
device. In addion, the applicable rules and regulaons for accident prevenon
at the installaon site are to be observed. Always keep the operang manual at
the installaon site of the PULVERISETTE 11.
People with health problems or under the inuence of medicaon, drugs, alcohol
or exhauson must not operate this device.
The PULVERISETTE 11 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 qualied personnel. Qualied per-
sonnel are persons who, because of their educaon, experience and training as
well as their knowledge of relevant standards, regulaons, accident prevenon
guidelines and operang condions, 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 dened for skilled workers in IEC 364.
In order to prevent hazards to users, follow the instrucons in this manual.
Malfuncons that impair the safety of persons, the PULVERISETTE 11 or other
material property must be reced immediately. The following informaon
serves both the personal safety of operang 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 qualied personnel.
This operang manual is not a complete technical descripon. Only the details
required for operaon and maintaining usability are described.
Fritsch has prepared and reviewed this operang manual with the greatest care.
However, no guarantee is made for its completeness or accuracy.
Subject to technical modicaons.
2.2 Scope of applicaon
NOTICE
This laboratory instrument is designed for an 8-hour shi oper-
aon at 30 % duty cycle and not for connuous operaon.
The duty cycle is dened as the rao of load duraon to run
me. The run me is dened as load duraon plus pause me.
According to DIN EN 60034-1 (VDE 0530, IEC34-1) a connuous
operaon already takes place aer a standardised run me of
10 minutes. At 30 % duty cycle (DC = rao of load duraon to
run me) a load duraon of 3 minutes and a pause me of 7
minutes would be within standard.
If the standardised run me of 10 minutes is exceeded, then,
by denion, there would be a connuous operaon and
disproporonate temperature increases may occur, possibly
involving increased wear.

Safety informaon and use
The Knife Mill PULVERISETTE 11 is universally used for fast and gentle commi-
nuon and homogenisaon of wet, oily, greasy so, medium-hard and brous
samples.
2.2.1 Operang principle
For comminuon with the Knife Mill, the knife is screwed to the grinding vessel
from below and placed in the PULVERISETTE 11. The sample material is lled
into the grinding vessel, which is then closed with a lid. The knife speed can
be adjusted between 2,000 and 10,000 rpm using a dial. A 2-piece knife with
4 stainless steel blades is used for comminuon, or a 2-blade serrated stainless
steel knife for demanding samples.
2.2.2 Drive motor and speed regulaon
A universal AC motor is used as the drive. The speed can be adjusted in incre-
ments of 500 using the dial.

2.8 Electrical safety
2.8.1 General informaon
■The main switch (9) separates the device from the mains on two poles.
■Switch o the main switch (9) if the Knife Mill will be idle for an extended
period of me (e.g. overnight).
2.8.2 Protecon against restart
If a power failure occurs during operaon or if the device is switched o with
the main switch (9), the hood is locked. The hood lock is opened when power
returns. For safety reasons, however, the mill does not restart.
2.8.3 Overload protecon
■In the event of overload, the device reduces the power in a controlled
manner. The actual speed may vary depending on the cung material.
■The device switches o if the drive motor becomes too hot.
■The device switches o if the drive is blocked.
2.8.4 Operaon on GFCI (Ground-Fault Circuit Interrupters)
It is possible that the leakage currents will become marginal during operaon.
This may trigger the earth leakage circuit breaker. These values can quickly be
reached when all devices are added to the circuit.
Soluon: Circuit without an earth leakage circuit breaker or, if possible, increase
the earth leakage circuit breaker threshold.

NOTICE
Damage to the grinding vessel made of plasc
When grinding materials, make sure that they do not get hoer
than 110° C when using the standard PC plasc grinding vessel.
This can damage the grinding vessel.
The standard grinding vessel made of plasc PC is unsuitable
for samples containing fat or fruit. The acids contained therein
can irreversibly aack the grinding vessel (formaon of micro-
cracks).
NOTICE
The grinding vessel made of Tritan™ is food safe, tasteless, heat
resistant up to 85°C, colour stable, chemical resistant, dish-
washer safe up to max. 80°C (80 cycles, with manual cleaning
up to 300 cycles), free from bisphenol A (BPA) and free from
plascizers.
NOTICE
Due to the high energies and the blade geometry, high temper-
atures (around 60°C) can occur on the material to be ground,
depending on the speed and grinding me. This temperature
can have a strong/irreversible eect on sensive samples! (e.g.
denaturaon of organic samples)
