When machining short-chipping materials such as brass, cast iron, or

more frequently due to the special nature of the contamination.
Depending on the duration of use, usage profile of the machine and
different ambient conditions, it is necessary in particular to remove
and clean the labyrinth rings.
Do not clean the machine with compressed air.
Raised dirt particles may cause breathing difficulties or injuries
(especially of the sensory organs).
Furthermore, raised dirt particles or chips may reach spots where
they cause technical problems.
Do not use cotton waste for cleaning.
When cleaning with cotton waste, fibers or thread can get loose
