tion of the dust, you must take the ap-
propriate measures.

Warning
Safety equipment for preventing hazards
must be serviced and maintained regularly.

persons trained by the manufacturer must
check the equipment for proper functioning
at least once a year, i.e. check for leaks, fil-
ter damage, functioning of the controlling
elements, etc.

You can test the filtration capacity of the de-
vice using the test procedure specified in
EN 60 335–2–69 AA.22.201.2. This test
must be done at least once a year or more
frequently if the national regulations de-
mand it. If the test results are negative, the
test is to be repeated with a new flat-fold fil-
ter.
Note: Industrial vacuum cleaners/dedust-
ers must be maintained as needed, but at
least once per year, repaired as necessary
and checked by a skilled expert (qualified
as per TRGS 519 Nr. 5.4.3, paragraph 2).
The test result must be presented upon re-
quest.

the container should be cleaned regu-
larly using a damp cloth.
