Type of protection
This machine is not designed to be
explosion-proof.
Do not use this machine in
a location where explosive
substances are handled.
This machine must not be used to
separate hazardous materials ( i.e.
H[SORVLYHVÀDPPDEOHVUDGLRDFWLYH
substances, or highly reactive
substances ).
The user is responsible for all
risks associated with handling
any of these substances.
Damaged, cracked, corroded,
rusted or deformed
Discontinue use of the equipment
when its rotor found to have been
damaged, cracked, corroded, rust-
ed or deformed.
Otherwise failure may occur.
Usable number for cycles of rotors
Replace the rotors when the
VSHFL¿HGQXPEHURIXVDJHF\FOHV
are reached.
If the rotor is used continuously
even after the usable number of
cycles of the rotor has expired,
should the rotor get damaged an
accident may occur.
Hazardous material
Do not put any hazardous material
(explosive, chemically active,
organic, or radiation containing
material, or material contaminated
by pathogenic microorganisms) as
a sample of the centrifuge and do
not place it closer than 30 cm to
avoid a secondary accident
should the centrifuge accidentally
rotate and contact the material.
Installation
A clearance of 30 cm minimum
must be provided around the
centrifuge.
If the centrifuge is driven into
uncontrolled rotations due to a
failure, secondary damage can
result from energy absorbed by the
rotation.
Lid
Do not open the lid when the rotor
is spinning.
Physical contact with the spinning
rotor may cause serious injury.
Ground cable
Ensure that the ground cable
is connected to the grounding
terminal.
This precaution must be strictly
observed to avoid accidents due to
electric shocks or leakage.
Rotor and drive shaft during rota-
tion
Do not touch rotor and drive shaft
during the rotation.
Physical contact with the spinning
rotor or drive shaft may cause
serious injury.

Installation
Setting place
Do not install the centrifuge on
an inclined, slippery, or unstable
surface.
Violent vibration may occur.
Ambient temperature࣭ humidity
ޮDo not install the centrifuge in a
place where the temperature is
below 10 Υor over 40 Υ.
A place with the ambient tem-
perature beyond 40 Υcan
introduce undesirable build-up
of heat inside the centrifuge and
a place under 10 Υcan cause
the centrifuge malfunction and,
as the result, accidents.
ޮDo not install the centrifuge in a
place with poor ventilation.
Otherwise inside temperature of
the centrifuge may rise, resulting
in accidents.
ޮDo not install the centrifuge in a
place with high humidity ( rela-
tive humidity 85 % or above ).
Leak or accident may occur.
ޮDo not install the centrifuge in a
dusty place.
When the centrifuge becomes
dusty, possibly causing break-
down.

Cleaning
Do not use detergents exceeding
the range of pH 5 - 8 or chlorine
detergents for washing purposes.
Corrosion may damage the rotor

Do not remove the caution plates.
When a caution plate becomes

If not positively held in place,
the rotor or centrifuge can be
damaged, thereby causing
accidents.
Toxic or radioactive substances etc.
When centrifuging of substances
contaminated with pathogenic
bacteria, or toxic or radioactive
substances, always use containers
that are pathogenic bacteria, toxic
substance or radiation proof.
Otherwise, infections, intoxication
or radioactive exposure accidents
may occur.

The rotors expand and contract every time they are spun up and stopped, causing unavoidable metal
fatigue that limits their usable cycles. Therefore, usable number of cycles are provided as guide for
timely replacement of rotors.
To ensure safe operation, use of rotors beyond the usable number of cycles may lead to breakage of
the rotors.
[Usable number of cycles for rotors]
When the used number of cycles has reached to the table below, the rotors are considered to expire
the life.
Earlier replacement of the rotor may be necessary if any corrosion is present, or if lowered strength,
scratch or deformation due to misuse occurs.
In such cases, please contact your nearest dealer and have the rotor checked before using them
again.

However, such parts may deteriorate over time after repeated use.
We recommend replacement of resin parts when the rotor is replaced.
Usable Number of Cycles for Rotors
WARNING
Use of rotors beyond the usable number of cycles may lead to breakage of the rotor.
If the rotor is used continuously even after the usable number of cycles of rotors has
expired, should the rotor get damaged, the main unit of the centrifuge suddenly may
start to rotate; this could result in an accident causing injury or death.
