The method to be applied when removing covers for
cleaning purposes from areas that are not dust-tight
should also be specified in the operating manual.
6.2
Servicing
If the dust extractor's suction performance decreases,
and even cleaning the filters 5 (fig. 2) after
replacement of the filter bag 8 (fig. 4) does not
increase the suction performance any more, the
folded filter cartridges 5 (fig. 2) must be renewed.
Usually it is sufficient to clean the folded filter
cartridges 5 from time to time, using a soft brush and
water. Allow to dry before reinserting, to prevent the
dust from clinging to the moist filter.
To avoid heavy soiling of container and filter, remove
dry material from the container before vacuuming
liquids. Dry suction cleaning only with completely
dried-out device. Do not clean container and
accessories with abrasive commercial detergents.
Regularly clean the water sensors 13 (fig. 3) and
check them for possible damages.
