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%)

6
Multi-Purpose High-Speed Centrifuge 1248R and 1580R
4. Before connecting the power, check the rated voltage.
5. Should not use unapproved rotors and accessories.
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 Lid-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
the 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.

7
Multi-Purpose High-Speed Centrifuge 1248R and 1580R
Use the Emergency Lid-Lock Release function only when the lid 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 kind of corrosive gases.

4-2. Rotor Coupling and Disassembling
Action
1. Before coupling a rotor, clean the motor shaft and chamber with soft dry
towel.
4-2-1. Swing-Out Rotor
2. Mount a proper rotor into the motor shaft.
3. Grasp the rotor with one hand, and place Rotor Locking Tool
at the center hole of the rotor.
To assemble the rotor: Rotate the Rotor Locking Tool
clockwise until tightly assembled.
To disassemble the rotor: Rotate the Rotor Locking Tool counterclockwise.
4. Hang the appropriate buckets into the rotor.
Load the identical bucket at each wing for safety. (Do not
leave a vacant wing without bucket. All wings should hold
identical bucket. )
Remove dirt and dust around hooks of rotor and hanging part
of bucket.
5. Spin the rotor manually to check if bucket swinging is free enough and ever. If they do not swing freely,
apply the Lubricant (grease) to the linking area.
4-2-2. Fixed Angle Rotor
2. Mount a proper rotor into the motor shaft.
Grasp the rotor with one hand, and place the Rotor Locking Tool at the
center hole of the rotor.

12
Multi-Purpose High-Speed Centrifuge 1248R and 1580R
When you run a fixed angle rotor, make sure that the rotor lid is tightly closed. If you don‟t close the rotor lid
completely, it will be crushed.
☞For operational safety, this instrument has the automatic rotor recognition function.
4-3. Positioning of Sample Tubes
Action
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.
Correct Way of Sample Balancing and 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 7. Trouble Shooting.
4-4. Drain Hole
Action
1. Before the centrifuge starts, check if drain hole on the left side of the
instrument is completely tightened. If not, refrigerating efficiency could be
getting lowered.

6. Maintenance
6-1. Outer part of Instrument
1. Clean the outside of the instrument with dry soft cloth. If necessary, dip the cloth in neutral detergent
and clean contaminated area. Keep completely dry after cleaning.
2. Do not use any volatile chemicals such as alcohol and benzene, etc.
3. Be careful not to make scratches on the surface of the instrument. The scratches can cause corrosion
on the surface of the instrument.
If any rust appears, clean it with neutral detergents and keep dry.
6-2. 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.
3. This product is equipped with a drain hole that can drain water or condensate inside the chamber. If
there is any condensate or water inside the chamber, remove the drain cap and drain the water out
through the drain hole so that there is no water in the chamber.
1) Place the discharge container on the bottom of the Drain Cap located on the left side of the main
body. (* The discharge container is not provided separately.)
2) The Drain Cap located on the left side of the instrument can be opened by turning
counterclockwise to remove moisture or condensate from the chamber.
3) Wait until all the condensate in the chamber has been drained.
4) After draining the water in the chamber, turn the drain cap clockwise to tighten it. Close the drain
cap until it is completely in contact with the drain hole.
Precaution for Drain Cap and Hole
1. Should check whether the sealing-ring is attached on the drain cap.
2. Operate the centrifuge after checking drain hole is completely tightened. If not, refrigerating
efficiency could be getting lowered.
6-3. 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.
