Safety instructions
se parts are to be handled with extreme care.
Wear protective personal equipment.
• Please observe the relevant safety instructions
and guidelines regarding dust explosions.
• Always wear suitable protective equipment
when embrittling the mill feed with coolants
(liquid nitrogen or dry ice), (see laboratory gui-
delines and accident prevention regulations ap-
plicable to the laboratory).
• Ensure that pressure does not build up in the
grinding chamber (particularly when using
coolants).
• Caution: When using liquid nitrogen, the mil-
ling process must only be started when the li-
quid nitrogen has fully evaporated.
• Caution: Appliance parts may still be extremely
cold for some time after cooling with liquid ni-
trogen and should only be handled whilst wea-
ring protective equipment.
• Process pathogenic materials only in closed
vessels under a suitable extractor hood. Please
contact IKA
®
if you have any questions.
• Do not operate the appliance in explosive at-
mospheres, with hazardous substances or un-
der water.
• Only process media that will not react danger-
ously to the extra energy produced through-
processing. This also applies to any extra ener-
gy produced in other ways, e.g. through light
irradiation.
• Safe operation is only guaranteed with the ac-
cessories described in the ”Accessories” chapter.
• Always disconnect the plug before fi tting ac-
cessories.
• The appliance can only be disconnected from
the mains supply by pulling out the mains plug
or the connector plug.
• The socket for the mains cord must be easily
accessible.
• After an interruption to the power supply or
a mechanical interruption, the device does not
start up again automatically.
For protection of the equipment
• The appliance may only be opened by experts.
• The voltage stated on the type plate must cor-
respond to the mains voltage.
• Protect the appliance and accessories from
bumps and impacts.
For your protection
• Read the operating instructions in full
before starting up and follow the safety
instructions.
• Keep the operating instructions in a place whe-
re they can be accessed by everyone.
• Ensure that only trained staff work with the ap-
pliance.
• Follow the safety instructions, guidelines, occu-
pational health and safety and accident preven-
tion regulations.
• Wear your personal protective equipment in
accordance with the hazard category of the
medium to be processed. Otherwise there is a
risk of:
- projectile parts.
• Set up the appliance in a spacious area on an
even, stable, clean, non-slip, dry and fireproof
surface.
• The mill is to be operated only under the sup-
version of an authorized operator..
• Check the appliance and accessories before-
hand for damage each time you use them. Do
not use damaged components.
• The mill is to be switched off completely using
the rocker switch (Pos. A 13) before opening
the door.
• Excess pressure develops with closed collecting
vessels, in particular when using dry ice or li-
quid nitrogen. This can lead to ground material
escaping upwards out of the funnel.
• Feeding stock residue that remain in the funnel
may not be manually removed during operati-
on or with unsuitable tools e.g. screwdrivers.
They should only be removed with suitable
cleaning tools when the device is switched off.
• Fingers and/or other articles should not be
placed into the discharge cone (Pos. P 1/ S 1)
in order to clean it during operation. Cleaning
is only permitted when the device is switched
off and the power supply plug has been dis-
connected.
• No highly combustible materials may be cut up.
• Note: After longer grinding cycles the grinding
chamber and the crushing tools may be hot.
Let the mill cool off before cleaning or perfor-
ming any repair work.
• Note: Exercise extreme caution when assem-
bling, disassembling or cleaning the cutting-
grinding head, particulary with regard to the
sharp blade edges on the rotor (Pos. S 20). The-
