9.6 Replacing filters
Check the filter mats in the fan and in the outlet filter on the rear of the housing for
contamination. Replace the filter mats if required.
9.7 Cleaning and filling washing bottles
The washing bottle (2) filled with tap water serves to collect the off-gases from sparking
so that they are not released into the air.
From time to time, check the washing bottle is correctly filled. Clean and fill it if the fill
level is not correct or cannot be easily seen.
