repress the “ STOP & OPEN” button with the other to open the faceplate), and take out the
centrifugal tubes carefully. The whole separation process is done.
Step11 Turn off the power switch, and cut off the power of the centrifugal machine.
7. Safety Notice
1.This machine should not be used in the humid places with high temperature and large fugitive
dust.
2.To ensure the safety and its centrifugal effect, this machine should be placed in the solid,
quakeproof and horizontal platform, and all four undercarriages should be given the balanced
load.
3.The solutions in the centrifugal tubes should be seen as even as possible. If the solutions in
the tubes vary too much, there would be a large scale of vibration. In this kind of situation, the
operating machine should be stopped its operation and checked to meet the requirement of the
solutions in the tubes. The centrifugal tubes should be placed symmetrically in the even
numbers, and the nut caps connecting the rotors with the motor shaft should be tightened.
4.During the operation process, the centrifugal machine cannot be moved, and the faceplate
cannot be uncovered.
5.The faceplate should not be uncovered in the situation that the motor and the rotors do not
stop the operation completely.
6.The power supply has its own earth wire, so the null line and the earth wire cannot be used
together, so as to prevent the damage of electric shock.
7.After the whole separation, the centrifuge machine should be cleaned up in time, the power
switch should be turn off, and the power supply should be cut off.
8.It should be very careful to take out the rotors. The proper way is to knock upward slightly the
rotors on the bottom by using nonmetal tools (like the handle of the screwdriver) until the
connection between the rotors and the motor shaft becomes loose. The rotors should not be
pulled out directly with hands after loosening the nut caps, so as not to damage the flexible
support system of the machine.
9.The rotors ad the centrifugal tubes should be checked regularly. If there are any cracks or
aging phenomena, those components should be replaced immediately.
Instruction: There is an emergency device on the bottom of the machine. If the sample
should be taken out during the power outage, the faceplate can be uncovered by pulling
the stainless wire on the bottom after the rotors stop the operation. But this device is
forbidden to be used during the operation process.
