Accident Prevention
Prerequisite for the safe operation of the Fisherbrand
GT 4 / 4R Centrifuge is a work environment in compliance
with standards, directives and trade association safety
regulations and proper instruction of the user.
The safety regulations contain the following basic
recommendations:
• Maintain a radius of at least 30 cm around the centrifuge.
• Implementation of special measures which ensure that no
one can approach the centrifuge for longer than
absolutely necessary while it is running.
• The mains plug must be freely accessible at all times.
Pull out the power supply plug or disconnect the power
supply in an emergency.
Precautions
In order to ensure safe operation of the Fisherbrand GT 4 / 4R
Centrifuge, the following general safety regulations must be
followed:
• Do not manipulate the safety devices.
• The centrifuge should be operated by trained specialists
only.
• The centrifuge is to be used for its intended use only.
• Plug the centrifuge only into sockets which have been
properly grounded.
• Do not move the centrifuge while it is running.
• Do not lean on the centrifuge.
• Use only rotors and accessories approved for this
centrifuge. Exceptions to this rule are commercially
available glass or plastic centrifuge tubes, provided they
have been approved for the speed or the RCF value of
the rotor.
• Do not use rotors that show any signs of corrosion and/
or cracks.
• Do not touch the mechanical components of the rotor
and do not make any changes to the mechanical
components.
• Use only with rotors which have been properly installed.
Follow the instructions on the Auto-Lock™ in section
Rotor Installation.
• Use only with rotors which have been loaded properly.
Follow the instructions given in the rotor manual.
• Never overload the rotor. Follow the instructions given in
the rotor manual.
• Never start the centrifuge when the lid is open.
• Never open the lid until the rotor has come to a complete
stop and this has been confirmed in the display.
• The lid emergency release may be used in emergencies
only to recover the samples from the centrifuge, e.g.
during a power failure (refer to the section Mechanical
Emergency Door Release).
