7.6 Replacing filter cartridges
CAUTION
Damage due to dust release
Maintenance, cleaning, repair and emptying work may be done only by
expert personnel.

Set up locally filtered forced-air ventilation where the product is being
maintained, inspected or cleaned.
After an extended period of operation, the filters clog up slowly due to the ingress
of extremely fine dust in the pores. Jet pulse cleaning can no longer remove this
penetrated dust. Filters must be replaced with new ones.
The filter cartridges must be checked at least every 6 months with a visual
inspection for wear and damage.
After 1000 operating hours at the latest, the filter cartridges must be replaced with
new ones.
This work should be done only by an expert wearing personal protective
equipment!
If possible, filter replacement must be done when there is no work going on. This
process requires 2 people wearing personal protective equipment.
Also pay attention here to the supplementary maintenance instructions!
