CAUTION
If the cleaning sector is not easily removed (e.g. there is some material stuck) it is
still possible to hook onto the blade to pull out the second group of bearings. The
operator must however pay extreme attention because the sector could free
itself and fall during the operation.
CAUTION
The operator must use protective gloves while taking off the blade unit.
CAUTION
Should the blades be blocked, the operator must not use hammers or other iron
tools to help himself with the extraction, because the blades could be damaged
and also such tools could cause dangerous metals splinters flying off. If necessary,
use a nylon hammer, or place a piece of aluminium between the hammer and the
blade to be released.

It is prohibited to heat the blades or the spacers to extract them from the shaft
because they could be damaged.
