3. Detach the dust filter from the cov er plate. Do this by pus hing the two latches (reference 3 image 14-2) of the dust filter inwards.
4. 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 127.
In case the filter contains dust but doesn’t feel greasy then vacuum clean the dust filter. Se e procedure "Vacuum cleaning of the
dust filters", page 126.

where popcorn is consumed are s ubject to greasy air.

have a second set of dus t filters which can be used while cleaning the first set .
