2.2.1 Operating principle
2.2.2
2.3
Drive motor
Obligations of the operator
The material to be cut is moved in front of a plunger and fed into the
cutting chamber by means of a funnel. There, four rotating knives in
combination with three fixed knives cut the sample material. The cutting
chamber is closed at the bottom by a sieve insert. Comminuted material
is collected in a pot after it passes the sieve insert.
Driven by:
n 1~ 100 / 120 V motor,
n 1~ 230 V motor or
n 3~ 230 / 400 V motor.
A three-phase motor or single-phase motor without mechanical brake
serves as the drive.
Before using the PULVERISETTE 15, this manual is to be carefully read
and understood. The use of the PULVERISETTE 15 requires technical
knowledge; only commercial use is permitted.

If a noise level of 85 dB(A) is reached or exceeded, ear protection should be worn to prevent hearing damage.
WARNING!
The maximum accepted concentration (MAC) levels of the
relevant safety guidelines must be observed; if necessary,
ventilation must be provided or the machine must be operated under an extractor hood.
DANGER!
Explosion hazard!
– When Cutting 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 Cutting these kinds of substances, special safety measures must be taken and the
work must be supervised from a specialist.
The PULVERISETTE 15 is not explosion protected and is
–
not designed to cutt explosive materials.
n Do not remove the information signs.

Safety information and use
NOTICE!
Immediately replace damaged or illegible information signs.
n Unauthorised alteration of the PULVERISETTE 15 will void Fritsch's
declaration of conformity to European directives and void the guarantee.
n Only use the PULVERISETTE 15 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.
2.6 Protective equipment
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.
The cutting mill has a comprehensive safety system:
1. A safety switch monitors the closing of the closing lid during oper-
ation and prevents the cutting mill from starting up when the lid is
open.
2. There is a safety switch for monitoring the collecting vessel.
During operation, it monitors the position of the collecting vessel
for the material to be cut (3.5 l pot or 30 l container) and prevents
the mill from starting up when the container has been removed.
n Both switches fulfil the directives concerning personal protection.
n The cutting mill cannot be started when the closing lid is open or the
collecting vessel has been removed.
n The cutting mill stops when the closing lid is opened and the col-
lecting vessel is unlocked.
