6.6 Checks by Operator
The operator has to ensure that no important part of the centrifuge is damaged.
This especially refers to:
1. Motor suspension
2. Concentricity of the motor shaft
3. Fastening of the trunnions in the rotor
4. Rotors and accessories have a limited life. For safety reasons a regular
check is recommended after 50.000 cycles. Any changes like e.g. corrosion,
cracks, material abrasion etc. require special attention.
5. Screw connections have to be tight.
Furthermore, the earth wire must be checked regularly.
