8. Cleaning and maintenance
8.1 General notes for cleaning and maintenance
 Switch off the device by pressing the main switch and disconnect it from the
power supply.
 If necessary, clean the surface and the inside of the centrifuge with a damp, lint-free
cloth.
 Open the centrifuge when not in use so that any moisture can escape.
 Protect the centrifuge and rotor from intense UV radiation.
8.2 Notes for cleaning with glass breakage
 If glass breakage occurs during centrifugation, press the START/STOP button.
 Open the cover.
 Switch off the device at the main switch and disconnect it from the power
supply.
 Let the centrifuge cool down.
 Remove the 4 cross-head screws from the intermediate plate and remove the
intermediate plate.
 Carefully remove the butyrometers and sleeves.
 Remove the rotor with the supplied fork key.
 In case of glass breakage, remove all splinters immediately and completely.
 If sulphuric acid has leaked out, clean the interior of the centrifuge and the
sleeves immediately in accordance with the guidelines for handling acids.
9. Checking the unbalance switch-off
The function of the unbalance switch-off should be checked at regular intervals. This work
may only be carried out by authorized personal. The centrifuge must be supervised during
this check.
 Check that all sleeves are clean and free of foreign objects.
 Place a 10 g weight in one of the centrifuge sleeve.
 Close the cover and press the START/STOP button.
 The rotor accelerates and after a few seconds the centrifuge has to switch off. The
error message Ibal inbalanced appears on the display and a beep sounds. Pressing
the START/STOP button or opening the lid will silence the beep.
 If the centrifuge does not switch off, press the START/STOP button immediately. In
this case, the centrifuge may no longer be used. If you are unable to determine and
remedy the causes of the shutdown yourself, contact Gerber Instruments AG
Technical Service (see point 13).
 If the centrifuge with this weight switches off, remove the weight out of the sleeve.
The centrifuge is still ready for operation.
