1. Ensure that the centrifuge is placed on a firm and flat surface, and adjust the front two adjustment screws to the fuselage level to ensure uniform force to avoid vibration.
2. When the instrument is abnormal, do not disassemble and repair the machine. If necessary, please contact our professional staff .
3. When replacing or disassembling the centrifuge rotor, the centrifuge power supply must be turned off to avoid danger.
4. Please ensure that the instrument is well grounded and should have a separate ground wire.
5. When the whole machine is running, do not manually open the centrifuge door cover. Do not move the centrifuge when the rotor rotates.
6. Before each use, carefully check the rotor for cracks and corrosion spots. Do not use if not.
7. Check the rotor and motor shaft connection nuts for looseness before each use. If necessary, tighten with a matching wrench.
8. For operational safety, keep at least 50 cm of free space around the centrifuge .
9. If the tube breaks in the centrifuge chamber, be sure to clean the debris before using it again.
10 , the centrifuge should be placed in the area not exposed to ultraviolet light or direct sunlight, so as not to cause the surface of the centrifuge to fade and paint.
11. If there is any abnormality in the centrifuge, stop using the centrifuge immediately and contact us. If the centrifuge displays an error code, please contact us.
12. It is strictly forbidden to use the rotor at overspeed. Set the rotor number according to the rotor number on the instruction manual and use it at overspeed. The loss of the rotor accident is the responsibility of the user.
13. When the machine is stopped for a long time, the rotor should be taken out to prevent the shaft from rusting.
14. After the rotor is taken out from the centrifuge chamber, dry it with neutral detergent to prevent chemical corrosion. Store in a dry and ventilated place. Do not scrub the rotor with a non-neutral cleaner. The rotor center hole and the taper surface should be slightly lubricated. Grease protection.
15. The rotor installation and removal actions should be light, and the rotor should be taken up vertically, otherwise it is easy to bend the shaft.
16. If it is not used for a long time, clean the inner cavity of the centrifuge, dry the water, and apply a little grease protection on the motor shaft.
17. Do not put any objects on the door cover to prevent damage to the items on the door when the door cover is automatically opened.
18. Centrifugal tube dosing is as uniform as possible. If the difference is too large, large vibration will occur. At this time, stop the inspection and make the liquid meet the requirements. The centrifuge tube must be placed in even symmetry. (Allow weight error ≤ 1g ).
19. If there is a rupture of the centrifuge tube during operation, it will cause a large vibration and should be stopped immediately.
