is to improve durability as compared to a unit without the

ingestionshields.

Each ingestion shield can be easily removed for cleaning by

slipping a finger or coin underneath the removal recess and

pulling to release thecover.

The wool ingestion shields can be cleaned with soap and

water and a soft bristle brush in the event they get clogged

with polish and debris. Clean the shields as soon as you start

to see buildup on theoutside.
