5.2 Seals and radial shaft sealing rings
Sealing elements and shaft sealing rings must, for safety rea-
sons, always be replaced after maintenance work involving
opening, removing or otherwise modifying sealing elements.
5.3 Micro-fi lters
The degree of clogging of the fi lter mats should be checked
at regular intervals, depending on the ambient conditions /
conditions of use. i.e. the user is responsible for ensuring
that the fi lters are permeable.
5.4 Cleaning
There is a high risk of injury on the inside of the device due to
rotating parts during operation. Decommission the device in
all cases and wait until all moving parts have stopped before
opening, reaching in or inserting tools into the device. Secure
the device reliably against it being accidentally restarted dur-
ing the entire period.
Also make sure that no other dangerous situation can arise
when restarting after a standstill, e.g. as a result of a power
failure or blockages.
