3. Check the "air in" side of the dust filter for dust and/or grease.
In case the filter is contaminated with grease wash and dry the dust filter. See cleaning procedure
"Washing and drying the dust filters", page 319.
In case the filter contains dust but doesn't feel greasy then vacuum clean the dust filter. See procedure
"Vacuum cleaning of the dust filters", page 318.
Note: Grease on the filter can build up after several months in an environment contaminated
with greasy air. Note that areas where popcorn is consumed are subject to greasy air.
Tip: Take into account that the time needed to dry the dust filters may be 24 hours or more. For
that, it's recommended to have a second set of dust filters which can be used while cleaning the
first set.
