3.5 Starting and stopping the centrifuge

3.5.1 Starting the centrifuge

Press the "Start" button and the instrument begins to operate. The green indicator light on the button will
illuminate, the rotating speed will gradually rise to the set value and the countdown timer will begin to work.
If it is necessary to adjust the rotation speed during the centrifuging process, press the "Set" button until the
rotation speed shown in the RPM/RCF window is flashing. Then use the " " or " " buttons to adjust the
value. After that, the instrument will operate according to the newly set rotation speed.
Warning: While the machine is in operation, the operator shall not lean on the instrument. Non-
staff personnel shall not linger in the safe space.

3.5.2 Stopping the centrifuge

(1) As the instrument keeps running, the countdown timer gradually turns to zero and the red indicator light on
the stop button will illuminate. The instrument will begin decelerating from the operational rotation until it fully
stops. Upon that, a buzzer will sound, indicating that the instrument has stopped operating and the lid can be
opened.
(2) If the instrument has to be stopped during operation, press the
button will illuminate. The instrument will fully stop as stated above.
Note: It is prohibited to manually unlock the instrument if the rotor speed has not decelerated to a
safe range. Manually forcing the rotor to fully stop is strictly prohibited.

3.6 Imbalance detection

In case of the rotor not being equally loaded, the drive will turn off during acceleration. The rotor decelerates to
stand still.
When in the display "Time" the word "E9" (M9), the weight difference of the samples is too large. Distribute the
weight evenly.

4.MAINTENANCE

4.1 Maintenance and cleaning

4.1.1 General Care:

Maintenance of the centrifuge is confined to keeping the rotor, the rotor chamber and the rotor accessories
clean as well as to regularly lubricating the rotor insert bolts of a swing out rotor (if available).
The most suitable lubricant is the High TEF oil.
Lubricants containing molycote and graphite are not allowed.
Please pay special attention to anodized aluminum parts. Breakage of rotors can be caused even by slight
damage.
