it is heavily contaminated, soak and carefully push through. Rinse in
cold water. Avoid high mechanical stress (do not use a water jet).
NOTICE

ness of the air that is drawn in. Clean filter ring after every 500 hours of
service or more frequently if necessary.

cleaning cloths. Otherwise there is a risk of damage or deformation.

damaged connecting strips with original parts from ABB Turbochar-
ging.
