6 Maintenance
Fitting and dismantling the cutter
The rotating parts run at such high operating speeds that you
must be particularly careful when replacing the cutter. Failure to
observe the following points may lead to imbalance and have
grave consequences.
• Always fit two blades.
• Have the blades resharpened only by the manufacturer; never
use blades made of different materials.
• When you install the cover etc., follow the instructions
described in this chapter. When you reinsert the beaker
holder, make sure it sits firmly.
