1-2. Safety Precautions
Before using the instrument, please read this operation manual to ensure correct usage. Incorrect handling of the
instrument could possibly result in personal injury or physical damage on the instrument or its accessories.
1. ALWAYS locate the instrument on a flat, rigid and stable table capable of withstanding the weight of the
instrument and its spinning operation.
2. ALWAYS make a safety zone of 30 cm around the centrifuge to indicate that neither hazardous
materials nor persons should be permitted within the area during operation.
ALWAYS position the instrument with enough space on each side of instrument to ensure
proper air circulation.
3. ALWAYS install the instrument within a temperature and humidity controlled environment. (Permissible
ambient temperature: +5°C ~ +35 °C, Relative humidity: ≤ 85%)
4. Before connecting the power, check the rated voltage.
5. Should not use unapproved rotors and accessories.

4
Low-Speed Centrifuge 406
Only use rotors from Gyrozen Co., Ltd. with appropriate centrifugal tubes and suitable
adaptors to embrace sample containers tightly enough inside rotors.
6. Before operating the instrument, check if the rotor and the rotor lid are securely fastened.
Should operate the instrument with a rotor properly installed and secured to the motor shaft.
7. Mount the rotor on the motor shaft properly, check it with spinning manually.
8. Do not stop the rotor by touching with hand during the instrument is running.
9. Emergency Door-Lock Release should be performed only when spinning is completely stopped.
10. Should not exceed the rated speed or specific gravity. Samples whose density is greater than 1.2g/ml
must have reduced maximum rotational speed to avoid rotor failure.
11. The sample content should not exceed 80% of total capacity of a tube. Otherwise, it would cause
spillage of sample fluid and even the tube breakage.
12. ALWAYS load the tubes symmetrically with evenly weighted samples to avoid rotor imbalance. If
necessary, use the water blank to counterbalance the unpaired sample.
13. The operation speed should not exceed the highest value of the individual guaranteed g-forces of each
centrifuge, rotor, bucket or adaptors and sample container, especially the guaranteed g-force of sample
container should not be neglected.
14. The rotors should be cleaned and kept dry after every use for longer life and safety.
15. ALWAYS disconnect the power supply prior to maintenance care and service to avoid electrical shock.
16. ALWAYS use proven disinfection procedures after centrifuging biohazardous materials.
17. Should not centrifuge flammable, toxic, radioactive, explosive, or corrosive materials.
18. When it is necessary to use toxic or radioactive materials or pathogenic micro-organisms which belong
to the Risk Group II of WHO: “Laboratory Bio-safety Manual,” should follow national regulations.
Do not place dangerous materials within 30 cm distance around the instrument, and that is
also recommended by IEC 61010-2-020.
Use the Emergency Door-Lock Release function only when the door button on the control
panel is dumb under the condition of complete stop of rotor running.
Never try to open or move the instrument if it is not completely stopped.
If the power input is more than +/- 10% of the recommended voltage or fluctuates
frequently, it may cause malfunction of the instrument and often result serious damage.
Install the instrument at the place without any kinds of corrosive gases.

button. Door can be opened only when the operation is completely stopped and the power is on again.
If you want to open the door at the power failure, please refer to ‘4-6. Emergency Door-Lock Release’.
3-2. Rotor Coupling and Disassembling
Action
1. Before coupling a rotor, clean the motor shaft and chamber with
soft dry towel.
2. Mount a proper rotor into the motor shaft. Put the Washer ( ) at the
center hole of the rotor and assemble it with Rotor Locking Nut ( ).
To assemble the rotor: Rotate the Rotor Locking Nut clockwise until
tightly assembled.
To disassemble the rotor: Rotate the Rotor Locking Nut
counterclockwise.
3. Load the 15ml sleeves at every hole.
3-3. Positioning of Sample Tubes
1. Before loading sample tubes, check the water drop or dirt in the rotor hole or inner adaptor.
If there is a water drop or dirt in the rotor hole or inner adaptor, remove it with soft dry cloth.
2. Tubes should be placed in the rotor with same amount of samples at symmetrical positions.
Only use appropriate centrifugal tubes and do not exceed the speed beyond the tube’s max.
g-force.
For safety, fill the sample for 70~80% in the tubes.

Correct Way of Sample Balancing & Tube Usage
If the number of samples is not in pair, please load the control tubes at each symmetrical position. Otherwise,
it results noise and vibration, which eventually damage the instrument.
☞
For safety, the ‘Imbalance Cut Off’ function will be occurred, if there is imbalance of loading tubes (Error
8, Imbalance error). Please refer to 6. Trouble Shooting.

5-2. Chamber
1. Keep dry inside the chamber after every use.
2. If the chamber is contaminated, dip the cloth in neutral detergent and clean contaminated area.
5-3. Shaft
1. Always make special attention to clean the motor shaft to avoid any imbalance problem due to the
contaminants.
2. After using the instrument, take out the rotor from the shaft, and clean the shaft with dry soft cloth to
keep dry.
5-4. Rotor
1. If any parts are contaminated with samples, clean the rotor with soft wet cloth and keep the rotor dry.
2. Be careful not to make scratches inside or on the surface of rotors. Any small scratches can cause
Manual opening should be performed only when spinning is completely stopped. Otherwise, harmful
damage will be accompanied to not only operators but samples.

corrosion of the rotor and big damage to the instrument.
3. If you do not use the instrument, keep the rotor separately from the motor shaft and stand it upside
down.
5-5. Transportation of the Instrument
1. If you need to move or ship the instrument, be cautious to protect the motor shaft from any physical
impact or turbulence.
2. Do not mount a rotor in any cases of movement. Fill inside the chamber with proper materials to keep
the motor shaft on place and not to be influenced by physical pressure.

6-1. Check List
Symptom
Check List
Power failure
Connect the AC Power cord and make sure that the line is completely
connected between the instrument and power outlet. Check the power
switch is turned on. (Please refer to 3-1. Power on/off and Door Release)
Can’t be started
If the door is not closed completely, the instrument can’t run.
Check the Door LED on the display window and close the door
completely.

power. If it is not solved in shortly, open the door with the Emergency
Door-Lock Release Tool manually for safety of sample. (Please refer to 4-
6. Emergency Door-Lock Release)
Can’t close the door
Remove the dirt at the door latch and then close the door completely
again. If the door seems not being closed by mechanical reason, please
contact our service team.
Noise and vibration during running
Please check the balanced status of both the table and the instrument.
Please re-check the coupling status of the following three matches to
minimize the noise
1. the balanced way of coupling of the rotor into the motor shaft
2. the completeness of fixing of the Rotor Locking Nut on the
rotor
3. the matching status of rotor lid with the rotor
(Please refer to 3-2. Rotor Coupling and Disassembling)
Check balances of samples in the rotor. (Please refer to 3-3. Positioning
of Sample Tubes) and load the same weight of samples symmetrically.
6-2. Error Code
