VII. 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.
VIII. Warranty Service Instruction
The warranty period of this centrifuge machine lasts one year since its purchased day. During the
warranty period, if the machine is damaged by artificial factors, maintenance services would be
provided with some appropriate fee. After the warranty period, all repairs are billed atcost.
