Level the Centrifuge

CA UT I O N If you do not level the centrifuge, the centrifuge can crash because of imbalance.
If you move the centrifuge, you must level it again.
Do not move the centrifuge with a rotor attached to the drive shaft because damage can occur to the drive.
Do not put anything below the centrifuge feet to level the centrifuge.
Level the centrifuge as follows:
1. Put the bubble level on the top of the drive shaft in the centrifugation chamber.
2. Adjust the centrifuge feet until the bubble in the level is fully in the circle mark.
3. Turn the drive shaft with the bubble level around a full turn.
If 50 % of the bubble stays in the circle mark, the centrifuge is leveled. If more than 50 % of the bubble is out of the
circle mark, the centrifuge must be leveled again.
