SAFETY NOTICES
○Mechanical Safety
●Do not open the door while the rotor is spinning.
●Do not attempt to slow or stop the spinning rotor by hand.
●Do not incline or move the instrument while the rotor is spinning. Do not
place any object on the instrument or lean on the instrument.
●Do not attempt to unlock the door forcefully while the rotor is spinning.
●The centrifuge itself may move if the rotor fails during high-speed rotation.
Make sure there is a 30 cm area around the centrifuge that will allow for such
movement and do not allow individuals to enter into that area during
operation. Also do not place dangerous objects such as flammable or
explosive materials on top of the centrifuge or in the surrounding area.
●The overspeed decal must match the maximum speed of the rotor, because
the overspeed decal is a critical component that detects the over-speed of
the rotor: If an overspeed decal that is not compatible with the rotor is
attached, the rotor could break, resulting in damage to the ultracentrifuge.
●
Repairs, disassembly, and other modifications to the centrifuge are strictly prohibited
unless performed by a Thermo Fisher Scientific authorized sales/service representative.
●Do not use the other’s manufacturer’s rotor without Thermo Fisher Scientific's
permission.
●Check the chemical resistance chart attached to the rotor, and do not use
any sample inapplicable to the rotor (including the buckets). Using such a
sample could corrode the rotor (including the buckets).
●
Do not exceed the allowable maximum rated speed of the rotor or buckets in use.
●Do not use corroded, scratched or cracked rotor, buckets and assemblies.
Check that the rotor, buckets and assemblies are free of such abnormalities
before operation.
●When using a swing rotor, check that the buckets are properly engaged with
the rotor pins before operation. Wrong setting can cause severe damage to
the instrument. Make sure that all the rotor buckets are of the same type.
●If abnormal sound or vibration occurs, stop the operation immediately and
contact a Thermo Fisher Scientific authorized sales/service representative.
●Before using a rotor, be sure to read through the rotor instruction manual.
●Check the chemical resistance chart attached to the rotor, and do not use any
sample inapplicable to the tubes, tube caps, bottles, or bottle caps, etc.
Using such a sample could corrode or deteriorate such parts and the sample
leakage might occur.
●Use the rotor tubes and bottles within their actual capacities (see the
instruction manual).
●Do not use tubes/bottles that have exceeded their life expectancy. Failure to
do so could result in damage of tubes/bottles and the rotor and the centrifuge.
The life expectancy of tubes/bottles depends on factors such as the
characteristics of samples, speed of the rotor used, and temperature.
Always check for deterioration and damage (cracks, deformation, and so on) on
tubes/bottles before using them. Do not use the tubes/ bottles if you find such a problem.
●Mount the rotor onto the drive shaft gently and properly.
●Do not drop the rotor or apply excessive force to the drive shaft to avoid
damage to the drive shaft.

SAFETY NOTICES
●Install the rotor carefully and securely on the drive shaft (crown) in the rotor
chamber. Always place the rotor pin in the drive hole (crown hole) apart from
the crown pin.
●Take care not to get your hands or fingers caught in the door of the
centrifuge.
●Maximum rotor speed depends on the tubes or adapters to be used. Follow
the instructions on the rotor instruction manual.
●Approximately even quantities of sample in the tubes are sufficient for
balancing, and extremely different sample quantities must be avoided.
●Clean the inside of the drive hole (crown hole) of the rotor and the surface of
the drive shaft (crown) of the centrifuge once a month.
●Storing the rotor on the shelf is permitted if the shelf is taken necessary
countermeasures against earthquakes not to drop the rotor.
●Do not pour any solution such as water, detergent, or disinfectant directly into the
rotor chamber. Be careful not to leak the sample. Failure to do so might cause
the bearings of the drive unit and/or the sensors to corrode or deteriorate.
●Use the rotor log book to manage the life of the rotor.
●It is important to manage the life of the rotor. The life of each rotor is specific
and dependent upon the frequency and the total running time. Do not use
rotors whose lives have expired. If used, the machine can be seriously
damaged. (Follow the rotor instruction manual.)
●For details of the Zonal centrifugation, see the Zonal Rotor instruction manual.
●Do not press the touchscreen with a sharp-pointed object such as a ballpoint
pen.
●Be sure to remove the rotor from the rotor chamber when centrifuge is not
used for a long time or when the machine is moved. Otherwise the drive shaft
(crown) may be damaged.
○Safety during installation and maintenance
●To avoid electrical shock hazards, follow below when servicing the
centrifuge.
1) Be sure to turn off the POWER switch and turn off the distribution board of
your centrifuge room if your centrifuge is equipped with a three wire
power cord. Then wait at least three minutes and then remove the covers
from the centrifuge.
2) Be sure to turn off the POWER switch and unplug the power cord from the
receptacle if your centrifuge is equipped with a power cord with a plug.
Then wait at least three minutes and then remove the covers from the
centrifuge.
●When a power failure occurs during operation, it takes 3 hours or more for
the running rotor to stop completely because the rotor chamber is
depressurized and has less air to stop the rotor. Be sure to leave sufficient
time before opening the door of the rotor chamber.
●For maintenance and repairing of the rotors, tubes, etc., see the rotor
instruction manual and the rotor, tube, bottle, and cap instruction manual.
●After installation and before any test-run, this ultracentrifuge always needs
the internal check by a Thermo Fisher Scientific authorized sales/service
representative.
●Repairs, disassembly, and other modifications to the centrifuge are strictly
prohibited unless performed by a Thermo Fisher Scientific authorized
sales/service representative.
