Use a soft-bristle brush for cleaning around components.
Avoid getting moisture inside the chassis during exterior cleaning, especially
Clean the exterior surfaces of the chassis with a dry lint-free cloth or a
soft-bristle brush. If any dirt remains, wipe with a cloth moistened in a mild
soap solution. Remove any soap residue by wiping with a cloth moistened

chassis. Clean the filter whenever it becomes visibly dirty. You can easily
remove the chassis air filter from the bottom of the chassis by removing the
filter cover. To remove the filter cover, loosen the retainer screw. The filter
