Safety instructions
imbalances arise during centrifuging.
• The density of the substance or mixture of sub-
stances must not exceed 1.2 kg/dm 3 when the
centrifuge is running at maximum speed.
• If unusual noises occur when the centrifuge is
started, the rotor is not secured correctly. In
this case, immediately press "STOP" to stop the
centrifuge.
• While the centrifuge is running, the safety clea-
rance of 300 mm all around must be kept clear
of persons, objects and hazardous materials.
• In the event of a fault, never reach into the ro-
tor chamber when the rotor is rotating.
• Pressing the "Cover release" button while the
centrifuge is running opens the cover and trig-
gers a quick stop of the motor. This can lead to
poor centrifuging results.
• While the centrifuge is running, do not move
it or strike it.
• When centrifuging
hazardous substan-
ces or mixtures of substances which are toxic
or are contaminated with pathogenic micro-
organisms, the user should take appropriate
precautions. In such cases, centrifuging vessels
with special screw seals for hazardous substan-
ces must always be used. For materials in risk
groups 3 and 4, in addition to sealed centrifu-
ging vessels a bio-safety system must be used
(see the "Laboratory Biosafety Manual" issued
by the World Heath Organisation). No bio-safe-
ty systems are available for this centrifuge.
• If you are using aggressive chemicals, protect
the device from being damaged by these che-
micals.
• Broken glass centrifuging vessels and glass spl-
inters pose a risk of injury.
• In the event of unbalance or unusual noises,
switch off the appliance immediately. In additi-
on, if imbalances or unusual noises occur, send
the device to the dealer or the manufacturer
for repair, accompanied by a description of the
fault.
• Refer to the operating instructions for the ac-
cessories!.
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:
- splashing and evaporation of liquids
- body parts, hair, clothing and jewellery get-
ting caught.
• Set up the stand in a spacious area on an even,
stable, clean, non-slip, dry and fireproof sur-
face.
• The feet of the appliance must be clean and
undamaged.
• Check the appliance and accessories before-
hand for damage each time you use them. Do
not use damaged components.
• Before using the centrifuge, always check the
cover for cracks. If damage is evident, send the
device back to have the cover replaced..
• Before using the centrifuge, check the rotor for
secure attachment. Ensure the rotor is well se-
cured, see "Inserting and removing the rotor".
• The rotor is subjected to extreme forces. Seri-
ous internal material damage can occur as a
result of even slight scratches and cracks. Do
not use the device if the rotor is damaged.
• Do not operate the centrifuge if there is evi-
dence of damage to the centrifuge chamber.
• The device must be supervised when it is running.
• The appliance is not suitable for manual ope-
ration.
• Always load the rotors symmetrically.
• Load the rotor only as described in the section
"Loading the rotor" in the chapter "Setting up
and commissioning".
• Always load the rotor so that no impermissible
